UROCOPTIS, S. G. COCHLODINELLA. 177 



A typical Cuban specimen is figured (pi. 42, figs. 77, 78, 

 79.) It is strongly fusiform, the four later whorls rather 

 swollen, those above tapering to a truncation about half the 

 greatest diameter of the shell. The last whorl also tapers 

 rather strongly, has a low, hardly cord-like basal keel, some- 

 times nearly obsolete, and projects very shortly in front. 

 Whorls ordinarily 9-11. The surface is glossy, corneous, with 

 close, even, slightly sinuous but hardly arcuate whitish thread- 

 like striae, narrower than their intervals. The aperture is 

 oblique and almost circular, with a reflexed, slightly thick- 

 ened white lip. The axis is straight and simple. Length 13, 

 diam. 3.2 mm. 



Var. VARIEGATA (Pfeiffer). PL 42, figs. 80, 81, 82. 



"Shell fusiform-cylindric, truncate, rather straightly rib- 

 striate; longitudinally denticulate-streaked with whitish and 

 corneous, the apex reddish or brown. Whorls 12. A little 

 convex, the last a little protracted, carinated at the base. 

 Aperture circular, the peristome expanded, white. Length 

 17, diam. 4 mm.; diam. of aperture 3*4 mm." (Pfr.). 



Cuba: Very abundant on palm roots and in woods around 

 Matanzas (Pfr.; Bartlett). Carmelo and Marianao, near 

 Havana (S. N. Rhoads). Florida: Key West (Hemphill, 

 Rush et al.) ; near the mouth of Miami River, under stones 

 in open pine land, copiously (Rhoads, Pilsbry).
