220 HELIX-EULOTA. 



Helix (Dorcasia) suffodiens BTTG., Bericht. Senck. Naturf. Gesell. 

 1891, p. 267, t. 3, f. 10. 



This was taken for H.fodiens by Wallace (P. Z. S. 1865, p. 408), 

 and was not found by Martens. It differs from all related species 

 in the fine granulation and in the umbilicus which is nearly twice 

 as wide. (Bttg.) 



H. DISSIMILIS Semper. PI. 51, figs. 42, 43. 



Shell most narrowly umbilicated, globose-depressed, rather thin, 

 subdiaphanous, flesh colored ; ornamented with very minute tuber- 

 cles, and obliquely rugose-striated. Whorls 5, slowly increasing, 

 subconvex, the last subcarinated and at the peristome constricted. 

 Umbilicus very narrow, half covered. Aperture lunar, buff-flesh 

 colored inside ; peristome acute, reflexed, whitish within, the colum- 

 ellar margin reflexed, half covering the umbilicus. (Semp.) 



Alt. 10, greater diam. 15, lesser 13 mill.

Chlorcea dissimilis SEMP., Reisen, p. 233, t. 10, f. 8. 



This species is well characterized by the coarse granulation and 

 the strong constriction behind the lip, as well as by the narrow 

 umbilicus. Animal not examined. 



H. CARINIFERA Semper. PL 51, figs. 29, 30. 



Shell umbilicated, globose-depressed, rather thin, diaphanous, 

 buff-flesh colored ; obliquely and closely striated, very minutely 

 and densely punctate. Whorls 4, slightly convex, the last sub- 

 carinated, compressed around the umbilicus. Umbilicus narrow, 

 pervious. Aperture lunate rounded, flesh colored inside ; the peris- 

 tome is subreflexed, whitish, the columellar margin reflexed. (Seinp.) 



Alt. 12, greater diam. 17, lesser 15 mill.

Chlorcea carinifera SEMPER, Reisen, p. 233, t. 10, f. 1 (1880). 



The peripheral keel is much stronger and the spiral striae far 

 fewer than in H. fodiens. It differs from all other species in the 

 extremely dense minute punctation, visible only under a lens, which 

 is entirely lacking in H. fodiens. 



H. TENIMBERICA v. Mollendorff. PI. 58, figs. 12, 13. 



Shell rather openly and perspectively umbilicated, convex- 

 depressed, thin, transversely finely plicate-striated, and decussated
