twelve, simply pinnate, some of the posterior plumes bifid ; oral 

 tentacles short, wholly concealed under mantle ; eyes apparently 

 absent. Mantle brilliant purple with a yellow margin (continuous 

 in front and behind), and three longitudinal yellow stripes ; the yel- 

 low of the margin is really bright orange, bordered with white; the 

 median yellow stripe begins a short distance before the rhinophores, 

 and runs between them ; rhinophores dark purple ; foot white witii a 

 purple tint, or quite purple when contracted after death ; the end of 

 the foot is purple with a dorsal longitudinal orange stripe. The 

 purple color does not dissolve out in formalin.

NEW LAND SHELLS OF THE JAPANESE EMPIRE. 



BY HENRY A. PILSBUY. 



Chloritis hractealus n. sp. 



Shell depressed-globose, almost imperforate, very thin and fragile, 

 brown. Surface dull to the eye, under a strong lens seen to be very 

 densely covered with very small crescentic scale-like cuticular pro- 

 cesses, densely crowded, and arranged in nearly regular descending 

 rows. Spire convex. Whorls 4^, the inner slowly, the last rapidly 

 widening; separated by a deep suture. Aperture rounded, lunate, 

 the peristome simple and thin, at the columellar insertion abruptly 

 dilated, almost closing the umbilicus. Alt. 13^, diam. 18 mm. 



Nishigo, Uzen. Types no. — A. N. S. P., from no. 1)04 of 

 Mr. Hirase's collection. 



This most northern of all its genus is strongly distinct by its ex- 

 cessively minute, curved cuticular appendages, unlike the hairs of all 

 other species of Cldorltis. 



Pupisoma JaponicH)n n. sp. 



Shell globose-turbinate, umbilicate, light brown, very delicate and 

 fragile. Surface delicately striatulate. Spire conic, the apex ob- 

 tuse. Whorls 3^, strongly convex. Aperture very obliquely ovate.
