guish as variety zmdzlica7is. is characterized by 
its more compressed form, less high body- 
whorl, larger umbilicus and by the absence 
(under a lens), of any radiating striae. The 
shell under consideration is certainly not the 
same as Gastrodonta significans, Bland, also 
found in the same region. It is 7o¢ whitish as 
is the latter, and is closer to multidentata than 
to any other. 
In the same set of fine shells was a magnifi- 
cent specimen of Alesodon dentiferus, Binney, 
of no less than 28 mill. in diameter, and of a 
coarser sculpture than in the type; this fine shell 
(from N. Carolina) which may be called var. 
major, is probably the same as the one men- 
tioned by Mr. W. G. Binney in his “Manual 
of N. A. Land Shells,’ 1885, is of a darker 
colour and furnished with more impressed _re- 
volving lines than the northern form of the 
species. CE EPAUNCENG
