206 GASTROCOPTA. 



Gastrocopta barbadensis hojeda Pilsbry. Text-figs. 8, 8a. 



The shell is cylindroid-tapering, cinnamon brown to wood 

 brown, the whorls convex, the last one less compressed later- 

 ally than in G. curacoana. The angulo-parietal lamella is 

 bifid, but less distinctly than in curacoana and octonaria; it 

 shows no spur on the columellar side in a basal view. The

strong columellar lamella has a low tapering buttress below 

 the inner end, not always visible in a direct front view. 

 Upper-palatal and basal folds are small but distinct. The 

 lower-palatal fold is straight, and very muck shorter than in 

 G. curacoana or G. octonaria. The reflected peristome is mod- 

 erately thickened.

This form can be readily distinguished from other Gastro- 

 copta of the Curasao group by the far shorter lower-palatal 

 fold. It differs from typical G. barbadensis by the simpler 

 armature of the columella.
