more species as one, yet both had Pfeiffer’s description to work with, for 
they have copied it, as before mentioned. 
The shells of this species which I have seen have simply been la- 
beled as coming from Cuba.

DESCRIPTION. 
Sp. Ch. Size, medium. Shell, heavy and robust. Striations pres- 
ent, but not prominent. Examined 25 specimens. 
Form of shell, oval, the greatest diameter being on the second whirl, 
the first is very little smaller, and the third but slightly smaller than 
this, and from this last mentioned whirl the shell tapers to a rather blunt 
point, forming an angle of about 60 degrees. Th e striations are numer- 
ous, 20 on the first whirl, and occupy all but the two lowest whirls, are 
regular, but are not arranged in lines and are but slightly inclined from 
right to left. The striations are slightly furrowed on top but the edges 
are smooth and rounded, they are not widely separated, the depressions 
being about equal in width to the prominences. 
The aperture is quite small and contracts rapidly, measuring some- 
what less within than at the entrance, and the teeth are situated some 
distance inside the opening. The lower is short, about .05 and only .03 
high, it is placed about midway between the two walls, while the upper, 
wffiich is only represented by a protuberance is placed considerably above 
it. 
The margin is not produced forward beyond the diameter of the 
shell, is considerably thickened, measuring about .05, and the posterior 
portion is provided with a thin, though not very prominent edge. The 
frontal bar is very prominent and completely interrupts the striations. 
Color of shell, white externally, tinged with yellowish within the 
aperture.

OBSERVATIONS. 
Beyond question this species is related to S. alba, but whether as 
a remote progenitor or as an offspring it is difficult to state, although I
