NATICA SUBGLOBULOSA.-A’/^en?. 
Plate 8, fig. 12. 
[Ostl. Alpen., plate 13, fig. 13. Compare Nerita Klipsteinii; Hornes, 
Denkschrift., Kais. Akacl., vol. ix., plate 2, fig. 7*] 
A minute but well-formed shell, with a very small spire, 
and a rather full suture, i. e. not appressed—the lines of 
growth a little antiquated near it; a broad ovate mouth point¬ 
ed above, but blunt below, and no callosity on the inner lip. 
In all these characters it agrees better with Klipstein’s 
figure above quoted than with any of the other numerous 
species figured by him, or the few given by Munster. 
It was referred by Professor Suess to Nerita Klipsteinii> 
but I do not know anything of that species, except from 
Hauer’s figure. N. Klipsteinii has, indeed, oblique stake, but 
I prefer the above identification. N. Munsterii, Hornes, is 
nearer in shape, but still has a callous lip. Ours is probably 
only a young specimen. 
MONOTIS (HALOBIA) LOMMELI.— Wismann.

This shell is positively identical with that figured so well 
by the above authors. I do not see why it should not belong 
to tiie genus Monotis. To the M. salinaria which sometimes 
takes its place, it bears a strong resemblance, and the accidental 
enlargement of the anterior side is surely not enough, to give 
generic character. 
Locality. —Gunesgunga chiefly. The small specimens are 
from Rajhoti, at which place most of the other species above 
described are found. 
The preponderance of this shell, and of the Amm. floridus 
in a peculiar band of black slate among the limestones near
