58 BRACHYPODELLA, S.-G. SIPHONOL^EMUS, GYRAXIS. 



CROSSED J. de C., 1891, p. 142. SOWERBY, C. Icon., xx, pi. 3, 

 f. 19. 



In form it has great similarity to C. tumidula W. & M., but 

 differs from this species, as well as from C. obesa and cristata, 

 which are related in other respects, by the absence of a keel 

 on the last whorl (Weinland). I have not seen specimens. 



Subgenus SIPHONOL^MUS Pilsbry, 1903. 

 The shell is small, turrite, and usually entire, with straight, 

 simple and slender axis, cylindric neck, rounded 'below, and 

 delicately, vertically, striate, apical whorls, the striae very 

 fine and close, very low, often hardly or not perceptible. The 

 dentition is unknown. Eastern Cuba.

 regularly rib-striate. Whorls convex, the latter half of the 

 last whorl free, cylindric, projecting and descending, sculp- 

 tured with wide-spaced, lamellar riblets. Aperture circular, 

 the thin lip well expanded. Axis straight and simple.

The small size, regular and dense costulation, and the 

 straight neck with very widely-spaced ribs, distinguish this 

 species. It resembles B. dominicensis in size and general 

 shape, but differs in the round neck, finer sculpture and more 

 numerous whorls. The specimen figured is from Monte 

 Verde. 



Subgenus GYRAXIS Pilsbry, 1903. 



Slender, uniform, corneous, delicately-sculptured shells, 

 with a moderate or long neck, and with the axis gyrate in the
