NOTICES OF NEW JAPANESE LAND SHELLS. 



BY II. A. PILSBRV AND Y. HIKAS1C. 



Eulota (Euhadra) eutope n. sp. 



Shell umbilicate, depressed, tlie upper surface low-conic, lower 

 surface convex. Last 1^ wliorls white under a thin yellow cuticle., 

 which is in part worn off in the type specimen ; the periphery marked 

 with a narrow dark chestnut band, the edge of which appears above 

 the suture of the penultimate and last wliorls ; the inside of the um- 

 bilicus of the same dark color ; inner whor/s red-brown, the apex 

 whitish. Surface rather glossy, rather closely plicate-striate above, 

 somewhat smoother below the periphery. AVhorls 6, slightly con- 

 vex, regularly and slowly increasing, the last scarcely descending in 

 front, distinctly angular at the periphery, the angle almost disappear- 

 ing just below the lip. Aperture oblique, lunate, white and show- 

 ing the brown band within, peristome reddish-brown, a little thickened 

 within, the upper margin slightly expanded, the outer and basal 

 margins reflexed, columellar margin dilated. Alt. 24, greater diam. 

 39, lesser 34.5 mm. 



Prov. Kunchan, Riukiu. Type no. 1078 of Mr. Hirase's col- 

 lection. 



This very handsome Euhadra belongs to the group of E. merca- 

 toria. It is similar to that species in the umbilicus and shape of the 

 peristome, and the slow, regular increase of the whorls; but it differs 

 from mercatoria in the depression of the whole shell, the more angular 

 periphery, the finer and closer sculpture, and in coloration. Only 

 one specimen has been received. 



Eulota (Plectotropis) marginata n. sp. 



Shell broadly and openly umbilicate, convexly low-conic above, 

 convex beneath, solid and strong; light brown, surface lustreless, 

 sculptured with irregular growth-wrinkles only. Whorls 7, but 

 slightly convex, slowly and regularly increasing, separated by a 

 slightly impressed suture which is distinctly margined above. Last 

 whorl slightly descending in front, acutely carinate at the periphery, 

 the keel narrowly impressed on both sides; base convex, not angular 

 around the umbilicus, but very suddenly curving into it. Aperture 

 oblique, nearly as high as wide; the peristome slightly thickened
