BY II. A. PILSIillY AND Y. HIHASE. 



Eulota {Etihadra') eiiterpe n. sp. 



Sliell umbilicate, depressed, the upper surt'iice low-conic, lower 

 surface convex. Last l-^^ whorls white under a thin yellow cuticle, 

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

 with a nurrotv dai-k chestnut band, the edge of whicii appears above 

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

 bilicus of the same dark color ; i^mer whorls red-brown, the apex 

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

 somewhat smoother below tlie periphery. Wliorls 6, slightly con- 

 vex, i-egularly and slowly increasing, the last scarcely descending in 

 front, distinctly anc/tdar at the peri jjhery, the angle almost disa^ipear- 

 ing just below the lij). Ajierture oblique, lunate, white and show- 

 ing the brown band within, pei-istome reddish-brown, a little thickened 

 within, tlie u[)per margin slightly expanded, the outer and basal 

 margins reflexed, columellar margin dilated. All. 24, greater diam> 

 39, lesser 34.5 mm.

 lection. 



This very handsome Euhadra belongs to the group ot 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'm the depression of the wiiole shell, the more angular 

 periphery, tiie 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, surlace lustreless, 

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

 sligiitly 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 umliilicus, but very suddenly curving into it. Aperture 

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