31G F0RAM1NIFERA OF THE CRAG. 



Rosalina, sp., Beissel, 1891. Abhandl. k. Preuss. Geol. Landes., n. s., part 3, 



p. 75, pi. xvi, figs. 17—22. 

 Anomalina geosseeugosa, Be Amicis, 1893. Boll. Soc. Geol. Ital., vol. xii, p. 450. 

 — — Chapman, 1895, Proceed. Zool. Soc, 1895, p. 41. 



Characters. — Subnautiloid in shape, unequally concave on the two faces. 

 Less symmetrical than A. ammonoides, Reuss, and, like it, subject to variation in 

 details. 



Our figured specimen appears to be rather thicker than Giimbel's and thinner 

 than Brady's figures, and shows fewer chambers than either. Von Hantken's 

 figure shows a close alliance with ours ; and that given by B., S., and B. is thicker 

 than our specimen, and has its aperture contracted and more medial. 



There are several published figures of varieties of this form : — Rosalina rudis, 

 Giimbel (1868), is possibly the same; and with the two faces equally convex 

 there are Anomalina moniliformis, Reuss (184-5), and Truncatulina pusilla, 

 Deecke (1886). 



Occurrence. — Found living here and there in the Atlantic and Pacific at depths 

 ranging from 345 to 2160 fathoms. It occurs fossil in Eocene strata in the 

 Bavarian Alps, and in the London Basin ; and in the Miocene of Hungary.
