On some Foraminifera of Tithonian Age from the Stramberg Limestone of Nesbelsdort; By FREDERICK CEAPMAN, A.L.Y., F.R.hI.8.

[Read 1st March, 1900.1

(PLATB 5.)

DURING t.he past year or so I have been favoured by Dr. 1%. Itetiie:, of Olmiitz, with some specimens of Foramitiit’era atid it

sample of foraminifera1 material from the marl formed by the weathering of the Red Limestone of Nesselsdorf.

Dr. Perner has already published a paper on Tithonian Forarninifeia from the Stramberg Limestone *, i n which he describes three species from the red marly litneatoue, namely, Bulirnina vartabilis, d’OrbignJ , Cristellaria varians, Borneniann, and C. rotulata (Lam.). Beyond this record we have no infor- mation of the Foraminifera from beds of this particular age. Consequently the follou ing small series is of exceptional interest.

the chief characters of the te f t rebenible those of the above species.

Dating from the Lower Carhonit’erous rocks, this species ranges upwards iu fosailiterous strata t u the present day. It hae also occurred in the wired faunas from the Aptian beds of Surrey (Chapman).

The species Inuolutinn Joiaesi, Terquem & Piette *, is in soi11e respects similar to this fomi, for example in the character of tire granulation<, but the outline of the test is very dissimilar.

those from France. Frequent in the Xed Limestone of Nesselsdorf.

This species is somewhat like Textulnria conica, d’Orbigng *, i n its general shape. It differa, however, in the n u m e r i d arrangement of t h e chambers ; the aperture also is characteristic of Taloulina.

Another form which v. cuneiforniis resembles is VaIvulina p ~ l m t r o c l i u s , var. conipressa, Brady t, from the Carboniferous formation, but the latter is strongly concave on the apertural face.
