1?1t?~oduction.--The following Report deals with the Microzoa obtained froin the deep-sea soundings collected round Funafuti in 1896 by H.M.S, ' Penguin,' C'aptain A. M. Field, R.N., coininanding.

I have previously published four reports on the Foraminifera and 0stmcod;L of the various dredgings made by the Funafuti Expeditions between 18!M and 1898 * ; and the present report is practically final as regards the recent ~naterial. For the privilege of examining the present very interesting series of soundings I am indebted to Prof. J. W. Judd, U.B., LL.D., F.R.S., and the Coral Reef Committee of the Royal Society. The saniples wwe sent on to Melbourne, and reached me in January 1904.

Condition qf Jlaterial.-The collection of soundings lllilde hy H.M.S. 'Penguin ' consists of 23 samples of dry Globigerina ooze and shell or " coral sands," and 37 samples of soundings in grease, taken by the sounding- lead. The former, and a few of the latter, were contained in glass bottles and tubes, whilst the remainder of the samples in tallow were in paper envelopes. After spending some time in cleaning the tallow s:iinples, which, by the way, were of an especially refractory nature, and exairiining them microscopically, i t was seen that the result did not justiEy the trouble, since the cleaned material often yielded only a few specimens of the coninlonest and most ubiquitous types of' Foraminifera, chiefly of pelagic forms. The present work is therefore mainly based on the results from the dry soundings, although some of the more interesting of the tallow saniples are included.

Two of the dried soundings in this collection, viz. Nos. 3 and 19, were partially examined by me when working in the Geological Laboratory a t the Royal College of Science, London; and the results of a search for tlie Ostracoda were embodied in my paper published in 1902, entitled " Some Ostracoda from Funafuti." Those samples were then only partially worked over a i d none of the Foraminifera noted, so that they have now been examined more exhaustively, and the entire results herein included.

Beneath each perforated area there is a depression or excavation. The intercostal area is a moderately deep groove. Length of figured q)eciinen *725 mm. ; greatest witltlr *5 mm.

I have much pleasure in naming this interesting species after Professor J. W. Judd, C.B., to whom I am especially indebted for the privilege of working out portions of the material from Funafuti.

LOXOCONCHA LATISSIMA, G. S. EJrady. Lo.z.oconcha latiaairna, G, S. Brady ('78), p. 399, pl. 58. figs. 1 a 4

This is its first occurrence as a recent form. The species was originally described by Dr. Brady from the Antwerp Crag. By the shortness of the valves and their tumidy both the present examples appear to belong to female specimens.

The carapace differs from that of L. australis, to which it is in some points allied, in the subparallel sides, the distinct flanging of the extremities, and the small, impressed surface-punctures,

Occurrence.-Sta. 13, 1050 fms.; 20, 1215 fms.

Genus XESTOLEBERIS, G. 0. Sam.

XESTOLEBERIS MARGARITEA, G. 8. Brudy, Sp. (T) Qtheridea nmyaritea, G. S. B r d y ('66), p. 370, pl. 68. figs. B a-d. Xeatoleberia niargaritea, G. S . Brady ('80), p, 127, pl. 30. figs. 2a-g; Egger ('Ol),

This is a common form in the shallower waters of Funafuti, being found in the lagoon as well as on the outer slopes of the reef. Brady's localities for this species are the Mediterranean, Booby Island, and the 'Mauritius. Egger obtained it in ' Gazelle ' dredgings from the Australian Coast, Kerguelen Island, and Table Bay.

p. 466, pl. 3. figs. 27-30.


XESTOLEBERIS VARIEGATA, G. S. Brady. Xestolebwia variegata, G. S. Brady ('80), p. 129, pl. 31. figs. 8 a-g.

This species has already been recorded from dredgings off Ht. Vincent, Cape Verde,at 107-1150 fathoms; off Tongatabu, 18 fiithoms ; at Fiji, Samoa, and Noumea in shallow water. It was of frequent occurrence in the lagoon a t Funafuti, and was often found off Funamanu at 50 fathome.

Occurrence.--&a. 2, 1489 fms. ; a single valve. LINN. J0URN.-ZOOLOQY, VOL. XXX. 34


XESTOLEBERIS ACUNINALIS, Chapman. Xeatoleberis ammihalis, Chapman ('OY), p. 429, pl. 37. figs. 4 u-c.

Genus CYTHERURA, G. 0. Sars.

CYTHERURA TENUICOSTA, Sp. n0V. (Plate 57. figs. 24 a, 6.) Descriptio)l.-Ci~rapace elongate, narrow-ovate, coin pressed j seen from the

side, ventral and dorsal margins nearly parallel ; dorsal margin with a gentle median sinuosity and excavated posteriorly ; middle of dorsal margin straight and curving towards both extremities to meet the evenly rounded anterior border and the rather sharply pointed posterior prolongation. Carapace thickest towards the ventral border, the surface sloping convexly to the ventral, and with a transverse median depression ; surface-ornament consisting of about seven fine, sliarp, parallel, longitudinal costm, which become confluent at the extremities of the valve ; the interspaces crossed by faint stria.

Length -625 mm. ; height -23 mm. ; approximate thickness of carapace -21 mm.

4fiinities.-In gexieral shape, although more elongate, this species resembles Cytherura clnoata, G. S. Brady *. The ornament of the valve-surface in that species, however, consists of numerous, delicate, anastomosing ridges, whilst in the present species they are parallel and extend nearly the whole length of the valve.

Occurrence.-Sta. 11, 1417 fins. ; 20, 1215 fms.

Genus CYTHEROPTERON, G. 0. Sars.

CYTREROPTERON WELLINGTONIENSE, G. S. Brady. Cytheropteron wellingtoniense, G . S. Brady ('80), p. 36, pl. 34. figs. 4 a-d.

Previously described from Wellington Harbour, New Zealand. The anterior margin in our example is more evenly rounded than in the figure given by Brady.

Rpf. to :ypejorm : (3. S. Brady ('80), p. 138, pl. 34. figs. 3 a-d.

The type species was recorded from Kerguelen Island, 120 fathoms, and off Heard Island, 75 fathoms.

* G. S. Brady ('80), p. 133, pl. 29. figs. 7a-d.


The valves found in the present dredgings are generally typical, but the alar beak is sharply pointed and prolonged instead of obtusely rounded as in Brady's ' Challenger specimen.

Occurrence.-Sta. 10, 1485 fms. ; 13, 1050 fms.

CYTHEROPTERON ABYSSORUM, G. S. Brady. Cytheroptn-on nbyyasomnt, G. 5. Brady ('80), p. 138, pl. 34. figs. 3 a-d.

Described by Brady from one locality only, in the Southern Ocean, S.W.

Occurrence.-Sta, 11, 1417 fms. ; 13, 1050 fms. Separate valves not of Tasmania, 2600 fathoms.

uncommon.

Genus BYTHOOPTHERE, G. 0. Sars.

BYTHOCYTHERE RETIOLATA, Sp. nOV. (Plde 57. figs. 26 a, b.) Description.-Carapace elongate ; seen from the side compressed, subovate ;

of nearly equal width throughout, height less than one-half the length ; anterior extremity strongly arched, dorsal line nearly straight and excavate posteriorly, ventral border concave in the upper third, then widely convex and curving backwards to meet the posterior prolongation ; median area of valve tumid, highest towards the ventral region and posterior, sloping away to the anterior border ; a deep, curved sulcus parallel with and just within the anterior margin. Median area deeply excavated by a transverse fold or sulcus, extending, a third away from the ventral, to the dorsal margin. Surface-ornament consisting of a distinct raised polygonal network. Edge view subovate, compressed at the extremities.

Length ~ 8 3 3 mm.; height -318 mm. ; approximate thickness of carapace -3 mm.


BYTHOCPTHERE TUBERCULATA, Sp. n0V. ( P h ? 57. figs. 27 a, h.). Descri~tion.-Carapace sitbovn te, compressed at the extremities ; highest

a t the anterior, attenuated posteriorly. Seen from the side, elongate, sub- quadrangular, dorsal edge straight, and meeting the evenly rounded anterior margin a t a sharp angle ; antero-ventral angle rounded and widely curved along the ventral line ; posterior extremity produced to a broad point. Surface of valve with a rounded prominence a little in front of the median area on the dorsal margin, behind which is a curved transverse depression ; there is also a subventral ridge which carries a strong stout spine projecting outwards and downwards. Surface coarsely punctate and covered with strong prickles. Anterior margin dentioulate. A narrow flange exists along the greater part of tbe ventrd border.


Length 1.04 mm. ; height *458 mm. ; thickness of carapace, including the spines, *75 mm.

Afinities.-This species somewhat resembles B. armata, Chapman *, but there is no dorsal tubercle in the latter, whilst B. armata shows a costation of the ventral area which R. tuberculata does not.


Genus PSEUDOCYTBERE, G. 0. Sars.

PSEUDOCYTHERE CAUDATA, G. 0. Sars.

Pseudocythere catidata, (3, 0. Snrs ('66), p. 88 ; ff. 8. Brady ('687, p. 463, pl. 34.6gs. 49- 62, pl. 41. fig. 6 ; Bmdy, Crosskey, 8 Robertson ('74), p. 210, pl. 2. fig. 9 ; Q. S. Brady ('80), p. 144, pl. 1, figs. 6a-d; Brndy t Normm ('89), p. 225; Egger ('011, p. 463, pl. 8. figs. 33, 34.

This species is very variable, as pointed out by Dr. Brady, who regards all the Northern and Southern forms as belonging to on0 type. The distribution is very wide, extending round the shores of the British Islands, the N. Atlantic, the Mediterranean, the S. Atlantic, nnd the Southern Oceans. The Funafuti exnmples are comparable with the ' Challenger ' specimens, and are not uncommon in the deep dredgings named below. Egger obtained it off the Australian Coast at 357 metres.

Occurrence.-Sta. 13, 1050 fins. ; 20, 1215 fins.

PSEUDOOYTHERE FUNAFUTIENYIS, Sp. nOV. (PlatC 57. fig. 28.) Description.-Carapace compressed, elongate ; seen from the side, narrow,

subelliptical, higher in the posterior half, height less than one-third of the length ; anterior extreniity pointed and truncately rounded towards the ventral angle ; dorsil line sliglitly curved ; ventral margin nearly straight in the middle, but trunc:ited and excavated towards the posterior prolongation which lies close to the postero-dorsal angle. Surface finely lineate longi- tudinally over the whole length of the shell. Edge view narrow-elliptical, strongly compressed a t the extremities.

Length 1-02 mln. ; height -3 mm. Afiinities.-'l'he surface-ornament of this species is similar to that of

P. fiiegiensz's, Bmdy t, but in the latter it is confined to the extremities of the valve. The narrow form and peculiar outline of our example show it to be distinct from that species.

compares them with Brady’s recorded ‘‘ L. apiculata.”

I n relation to the question of the influence of light on the coloration of organisms in the ocean depths, i t is interesting to note tho occurrence of deepIy coloured tests of Po1,ytrema nainiacezivz a t a depth of 507 fathoms.

A special intorest attaches to some of the species found in these sainples, on account of the great depth a t which they were obtained. Particularly would we notice the forins occurrillg at depths from 2000 to 2728 fathoms, or from 2f to over 3 miles.
