This species has some resemblance to U. pup&formis, but in 

 that the stride are closer, flattened and glossy, the shell is of 

 stouter form, and the lip more developed. It is much more 

 like the Cuban B. angulifera and the Haitian B. imitatrix, 

 especially in the shape of the neck ; but the apex of inornata 

 shows the high, wall-like first half -whorl and deeply depressed 

 tip of all the Jamaican Brachypodellas. 



Adams' description mentions " two carinae which are not 

 prominent ' ' on the last whorl ; but the shells I have seen have 

 no carinse, merely a slight, hardly noticeable angle at the base, 

 and a swelling at the periphery, above and below which the 

 sloping surface is somewhat flattened. The striae are narrow 

 and thread-like, separated by much wider intervals. Size of 

 truncate shells varies from 9 x 2.5 to 10.5 x 2.7 mm., with 

 about 8 whorls. An entire specimen from Hanover (Clapp 

 coll.) is 12.2 mm. long, and has 151/2 whorls. 



It is a widely distributed form, though apparently found 

 nowhere in copious quantity. It occurs over the high interior 

 of the western two-thirds of the island, not descending to the 

 lower levels near the coast. I have observed no mentionable 

 variation in specimens from the localities recorded above. 



42. B. SIMPLEX (C. B. Adams). 



" Shell subovate or fusiform, moderately elongated; whit- 

 ish ; with very oblique, straight, faint striae, with one moder- 

 ately sharp carina at the anterior extremity, and another
