BRACHYPODELLA, S.-G. GYRAXIS. 61 



brought forward in a strongly arcuate curve. Surface deli- 

 cately, regularly striate, the neck ribbed. Whorls moderately 

 convex, the last carinate below, the keel not extending upon 

 the free neck. Aperture subvertical, circular, the lip thin, 

 narrowly reflexed. Axis (pi. 64, fig. 8) slender, nearly 

 straight in the upper whorls, but gradually becoming sinuous, 

 spirally coiled, in the later ones. 



Length 11.4, diam. 1.8 mm., whorls 18. 



Length 10.4, diam. 1.8 mm., whorls 17.

Near B. turcasiana, from which the less convex whorls, the 

 last compressed and obtusely carinate below, the longer neck 

 and subvertical aperture, separate it. The shape of the last 

 whorl recalls B. brooksiana. The axis is like that of B. tur- 

 casiana. The specimens from Monte Toro are a variety with 

 straightly descending neck. Sowerby's figures of "turkasi- 

 ana " are probably this species. 



The original description follows: " Shell very slender, sub- 

 truncate, fusiform, tapering towards both ends, very finely 

 striatulate, pale corneous, glossy. Whorls 16-18, nearly fiat, 

 the last disjoined and much projecting, very closely costulate- 

 striate, the base carinate. Aperture oblique, circular; peris- 

 tome narrowly expanded throughout. Length 11.5, diam. 1.5, 

 aperture 1 mm." (Poey). 



According to Poey, this species differs from C. gracillima 

 by the more numerous whorls, less cylindric form, glossy tex- 

 ture, etc. ; from C. porrecta Gld. by the well-marked keel, the 

 close striae of the neck, by being a little more swollen and 

 shorter. It was unknown to Arango, and has not been fig- 

 ured hitherto ; but I believe that the East Cuban specimens I 

 have described and illustrated are referable to Poey's species..
