34 PROCEEDINGS OF THE ACADEMY OF [March, 



spire has convex oiithnes and an obtuse apex. Whorls 6J, convex, 

 very slowly widening, the last one very slowly and slightly descending, 

 indistinctly angular at the periphery in front, becoming rounded on the 

 last half. The aperture is quite oblique, very much larger than the 

 umbilicus. Peristome thin ; outer margiji only very slightly expanded ; 

 basal margin deeply arcuate, slightly expanded; columellar margin 

 broadly, triangularly dilated. The terminations of the lip are widely 

 separated, parietal callus very thin. 



Alt. 10.5, diam. 12 mm. ; alt. and width of aperture 6 mm. ; width of 

 umbilicus 3 mm. 



South Nishigo, Uzen. Type No. 94,740 A. N. S. P., from No. 1,438 

 of Mr. Hirase's collection. 



This peculiar Aegista has some superficial resemblance to Trish- 

 oplita hilgendorfi Kob. It is closely related to E. eminens P. and H., 

 but differs in being larger, stronger, with less scaly sculpture, and a 

 little less strongly angular. It is quite possible that intermediate 

 provinces between Shima and Uzen will be found to have connecting 

 links between E. eminens and E. celsa ; yet at present they seem to be 

 sufficiently distinct. 



The type specimen is higher than others in the type lot. The lower 

 ones have less convex outlines, the spire being less convexly conic; 

 the last two whorls have sculpture of long granules in places ; and the 

 umbihcus is much wider than in the type. Alt. 9, diam. 13.8 mm.; 

 aperture 6x6 mm. ; umbilicus 3.5 mm. wide (celsus, lofty). 



Ena reiniana vasta n. subsp. 



Shell very large, cylindric. The cuticle is glossy, yellowish brown, 

 and copiously granulose except on 3 or 4 earliest whorls; but many 

 old shells have lost the cuticle and sculpture in part or wholly. Whorls 

 8 to 9^. 



Length 37.5, diam. above aperture 11 mm.

S. Nishigo, Uzen. Types No. 94,686 A. N. S. P., from No. 1,439 

 of Mr. Hirase's collection. 



This is the largest of the Japanese Buhmini. It is larger than 

 Ena reiniana omiensis, and copiously granular when unworn. 



Ena reiniana ugoensis n. subsp. 



Shell very short and obese, reddish on the spire, whitish on the last 

 whorl, under a thin yellow cuticle; granulation only weakly developed. 



Whorls 7i.
