Toba, Shima. Types No. 87,656, A. N. S. P.. from No. 5a of Mr. 

 Hirase's collection. 



This is a larger species than E. commoda A. Ad., with less conic spire 

 and better developed peristome. 

 Trishoplita nitens n. sp. 



Shell umbilicate, depressed, with very low conoid spire, obtusely 

 angular periphery and convex base; thin, glossy, rather bright green- 

 ish-yellow, the earlier Avhorls denuded and bluish-white. Surface 

 weakly marked with wrinkles along growth-lines, and showing some 

 very faint spiral striae on the base. Whorls 5, slowly increasing, the 

 last wide, slightly defiexed in front. Aperture oblique, oval-lunate, the 

 peristome thin, narrowly expanded. 



Alt. 6.5, diam. 11.5, width of umbilicus 2 mm. 

 Tokunoshima, Osumi. Types No. 87,598. A. N. S. P., from No. 

 1,231 of Mr. Hirase's collection. 



A very bright, glossy and depressed species, of a genus not before 

 reported from any island south of Kyushu. 

 CMoritis obscurus n. sp. 



Shell umliilicate, somewhat depressed, the spire low-conoidal; thin, 

 and dull, dark brown. Surface lusterless, slightly striate and indis- 

 tinctly punctate in places, the points bearing no hairs 

 and rather irregularly spaced. Whorls nearly 5, the last 

 about double the width of 

 the preceding, very slightly 

 descending at the aperture, 

 rounded at the periphery. 

 Aperture broadly lunato- 

 oblique, the peristome thin, 

 l^rown, narrowly expanded 

 y / throughout, more broadly 



dilated at the umbilical 

 insertion. 



Alt. 9, greater diam. 13, lesser diam. 

 11.3 mm.; umbilicus 1.8 mm. wide. 



Tokunoshima, Osumi. Type No. 

 1,227 of Mr. Hirase's collection. 



A small, dull species, known by 

 a single specimen, but very unlike 

 any other Riukiuan or Japanese species 

 yet known. The convex spire and 

 expanded Hp, as well as the very obscure punctulation, are its more 

 prominent characteristics.
