Sp. Char, The crucial characters of this fossil, viz. those of the 
aperture, are wanting, and therefore we have only the general form 
to serve as a guide to its affinities. The fusiform shell, one side a 
little inflated, the other nearly straight, presents very much the 
aspect of a Gomphoceras, or at least a closely allied genus. The 
subject of the present description is a compressed (?) fragment, 
consisting of part of the septate portion of the shell and an equal 
amount of the body-chamber, the whole measuring nearly two 
inches in length. The section is elliptical, the ratio of the two 
diameters in the most inflated part of the shell being as 11 : 13. 
The septa are approximate, the most distant not being more than 
one line apart. A portion of the test is preserved, and is seen to 
be ornamented with lines of growth of varying degrees of fineness. 
The siphuncle is not seen. 
Remarhs. Munster appears to have included more than one species 
under the name of suhfusiforme, his figures 7 and 9 {loc. cit.) illus- 
trating a shell having much more widely spaced septa than are those 
of fig. 8, to which I have referred the specimen in the National Col- 
lection. The same dissimilarity exists between the latter and the 
fossil figured by Portlock. Eichwald ^ makes Miinster’s species 
(restricted to figs. 7 and 8 of that author) synonymous with Gom- 
phoceras Eichwalcli, de Yern. ; but de Yerneuil affirms that his 
species is clearly distinguished from Miinster’s by the great size of 
its siphuncle, which occupies nearly J of the diameter of the shell.

This is a fragment consisting of the upper part of the septate 
portion and the lower part of the body- chamber of a shell whose 
general form strongly suggests affinities with Gomphoceras. The 
fossil, though crushed, is considerably inflated in the middle and 
tapers at both ends. The septa are crowded together near the
