UROCOPTIS OF HAITI. 157 



Length 22, diam. 6.7 mm. ; whorls 8. 



Length 23.5, diam. 6.7 mm. ; whorls 9. 



Length 25, diam. 7 mm. ; whorls 9. 



This is a narrower shell than sericea or eugenii, and with 

 the peristome less adherent above. The short plug is also 

 probably characteristic, but this has not been described in the 

 types of sericea, eugenii or kisslingiana. 



Var. eugenii (Dohrn). PL 39, figs. 34, 35, after Crosse. 

 Shell deeply rimate, subcylindrical, tapering above, truncate; 

 livid hyaline, thin, obliquely striate, the suture submarginate. 

 Whorls remaining 8, nearly flat, the last rounded, anteriorly 

 angular on the back, compressed-carinate in the middle, 

 roughly striate on the base and behind the peristome. Aper- 

 ture subvertical, subcircular; peristome white, expanded and 

 a little reflexed throughout, shortly adherent in front. 

 Length 25, diam. 8 mm. ; apert. with peristome 6 mm. long 

 and wide (Dohrn). Northwestern Haiti (Dr. Eugene Vesco). 



Var. kisslingiana Weinland (pi. 41, fig. 64). Shell rimate, 

 oblong- cylindrical, truncate, smooth, very finely striatulate, 

 more distinctly so above and below, glossy, diaphanous whit- 

 ish, roseate above, the suture indistinct, white-margined. 

 Whorls remaining 8 l / 2 to 9 l / 2 , nearly flat, three or four median 

 ones equal, the last one narrower, appressed, base with a cord- 

 like keel. Aperture nearly vertical, subcircular, obsoletely 

 channelled in the base ; peristome a little expanded, thickened, 

 reflexed, resting upon the penult, whorl, sometimes inter- 

 rupted there. Internal column simply twisted, without la- 

 mellae. Length 29-30, diam. above the middle 9-9 1 /2, apert. 

 with perist. 7 mm. (Weinl.). 



Gonaives, Haiti (Kissling). 



Var. major Weinl. Whorls 10^2 ; length 37, diam. above 

 middle 10 mm. ( Weinl. ) . A single specimen found with var. 

 kisslingiana. 



32. U. GRUNERI (Dunker). PL 39, figs. 16, 17, 18, 19. 



Shell oblong, widest at the, penult, whorl, the last three 

 whorls wide, those above rapidly tapering to the narrow con- 

 cave truncation; solid and strong except near the aperture,
