DESCRIPTION OF A NEW FOSSIL CYPREA. 
BY JOHN H. CAMPBELL. 
Cyprea Squyeri n.s. Plate II, figs. 1, 2. 
Shell ovate-oblong, attenuated at the extremities. Spire promi- 
nent, showing four whorls; outer lip thickened and having on the 
inner edge thirteen or fourteen teeth. Anterior half of the aper- 
ture wide, but contracted at the extremity, posterior end contracted 
and projecting slightly beyond the spire. Under the magnifying 
glass the shell shows strong revolving raised lines and _striz. 
Length 20 mm., width 11 mm., height 9 mm. 
A notice of the finding of this shell by Mr. Homer Squyer of 
Mingusville, Mont., in the cretaceous formation (Fox Hills Group) 
of eastern Montana, and the above proposed name, were published 
in the Nautitus Vol. VI, p. 50. This shell resembles in outline 
the recent Cyprea stolida, but its very prominent spire would sepa- 
rateit from this group. Shell structure is wanting on most of its dor- 
sal surface and the inner lip obscured by the hard matrix, which it 
would be inadvisable to remove. In a recent letter from Mr. 
Squyer he says “ This summer while looking for fossils I found the 
outer lip of the imperfect specimen, found at the time I obtained 
the type. This specimen I have sent to the U. S. National 
Museum.” The type has been placed in the collection of the 
American Association of Conchologists.
