MIOCENE MOLLUSCA AND CRUSTACEA. 109 
of figures only, but with some doubt. On comparison with authentic spec- 
imens of that species it differs materially in the dentitions of the columellar 
lip, that one having only very slight crenulations on the lower end, and 
only one, the lowest, that might be called a ridge. The crenulations of the 
outer lip are also stronger and less numerous. 
Formation and locality: The specimens used are from the gray mica- 
ceous marls of the Miocene at Jericho, N. J., and belong to the National 
Museum collections. Dr. Emmons’s specimens were from Cape Fear River, 
North Carolina.

“Cylindrical; spire short, conical; whorls concave or angulated; colu- 
mella strongly plaited throughout; substance of shell very thick at base.” 
A fragment of the outer volution of a two-thirds grown specimen of an 
Olive occurs among the collections, which I suppose belongs to the above- 
named species. The shell, being from a partially grown specimen, is not so 
thickened as it might have become at an older stage, and in its present con- 
dition shows no features that might not readily exist on specimens of Oliva 
litterata. In fact I can see no reason for separating the Miocene form found 
in the more Southern States from the shells living along the Atlantic coast. 
Locality: The fragment comes from the Miocene marls at Jericho, 
N. J., and belong to the collections of the National Museum.
