tions are available. 
Judging by the photographs, Hyalinia heepingi is a larger shell than either 
H. @urbani or H. omphatoides, being about 12 mill. in diameter, with a convex 
spire of about four whorls, somewhat rudely and irregularly striate in the line 
of growth. 
The H. omphatoides is © much smaller shell, but with about 55 whorls, the 
largest specimen measuring about 7 mill. in diameter, with distinct and deep

sutures, and somewhat irregularly undulate strive in the lines of growth; the 
umbilicus is open and distinct, and about mid-way between the umbilicus and 
the angulate periphery there is a well-marked basal keel of which no trace can 
be seen in the published figures of H. @urbani or H. morrisir.

This species is considered as distinct by Mr. F. E. Edwards and Mr. 
Searles V. Wood, but regarded as a form of //. @urbani by Mr. Gardner. 
Judging from the published figures here reproduced, //. morrisi? appears 
worthy of specific recognition. 
It belongs to the Oligocene fauna, and according to Mr. Wood bears a 
slight resemblance to Helix heberti Desh. from the Lower Tertiaries of 
France, but still more closely approaches the //elix dubia Desh., a 
species whose presence in our English deposits is demed by Edwards.
