44 THE NAUTILUS. 



U. PROTEUS CASTANEA, P. var. 



Differs from the type in being of uniform brown, with last whorl 

 purplish. The suture is more distinctly crenulate. 



Long. 18, diam. 5.5, ap. 3.3 mm. Whorls 9. 



Long. 15, diam. 4.8, ap. 3.2 mm. Whorls 8.5. 



Long. 16, diam. 5, ap. 3.3 mm. Whorls 9. 



Central Cuba; Colonia Santa Cruz between Seibabo and Yaguajay 

 in the province of Santa Clara. 



Differs from U. remediensis by the somewhat swollen shell, rapidly 

 tapering to a broader truncation, more solid, and chestnut-colored 

 without whitish spots; rib striate and more crenulate, etc. The axial 

 lamellse are also somewhat differently disposed. 



U. PROTEUS ROBusTAxis, n. var. 



Shell smaller, cylindric, somewhat swollen, rapidly tapering to a 

 very narrow truncation ; somewhat solid; pale chestnut with obsolete 

 whitish clouds; oblique, regularly rib striate; suture not crenulate. 

 Whorls 9-10.5, a little convex, the last one more free. Aperture as 

 in U. proteus, typical. Axis tri-lamellate, rather strong and stout in 

 the last whorls. 



Differs from the variety castanea by its simple suture, more pro- 

 jecting last whorl, stouter axis, and by its color pattern of a few 

 white and chestnut spots on pale brown ground. The last whorl is 

 purple, as in the type. 



Long. 18, diam. 4.8, ap. 3.8 mm. Whorls 10.5. 



Long. 17, diam. 5, ap. 4 mm. Whorls 9. 



Long. 17, diam. 4.7, ap. 3.5 mm. Whorls 10. 



Central Cuba; Sierra de Santa Rosa between Remedios and Sei- 

 babo de Yaguajay in the province of Santa Clara. 



LTrOCOPTIS (GoNGYLOSTOMa) REMEDIENSIS, n. sp. 



Shell rimate, cylindric, the upper third (or half) tapering to the 

 truncation ; thin ; brown with opaque whitish flames. Surface 

 obliquely weakly striate ; suture slightly crenulate. Whorls 8-10, a 

 little convex, the last purplish, shortly free in front with a cord-like 

 keel around the base. Aperture slightly oblique, ovate roun<led ; 

 dark brown within, but the peristome, columella and upper wall 

 nearly white. Peristome expanded and reflexed throughout. Axis 

 encircled by three compressed lamellse, the lower denticulate in the 

 upper and median whorls.
