In his remarks upon this species, Mr. Guppy suggests the 
possibility of this and the next form being “sexes” (!) of one and 
the same species. As these Pulmonates are supposed to be 
androgynous, we can well understand Mr. Guppy’s difficulty to 
“advance any evidence in support of this view.” Professor 
Pilsbry (Man. Conch., ser. 2, vol. ix, p. 57) suggests that this 
species is probably a mere variety of Z. /A/agzoptycha Shuttle- 
worth, an opinion which is evidently correct.

Hab.: Jamaica (Adams); Vieque (Pfr.); Trinidad (Guppy); 
Yucatan (Morelet). 
Having compared specimens of the above three forms, I 
concur with Mr. Pilsbry in considering the two latter as ‘“‘varie- 
ties of dzescoricola.”
