48 AMPULLARIA CRASSA, VAR. 
Hab. Mount Cottica in French Guyana. 
Type in the Leyden Museum. 
The specimens seem to me to be fullgrown, owing to 
the thick callus on the inner lip, and the rather broadly 
reflexed columellar margin. The shells are very much 
eroded at the apex. The colour is olivaceous brown; the 
whorls are encircled by several wider and narrower blackish 
brown bands. The surface, which seems smooth to the naked 
eye, appears under a strong lens to be finely granulated.
