deprived of cuticle; surface lustreless, weakly striate; acutely 

 tapering above to a small acd rather acute apex. Whorls 10, 

 moderately convex, the last compressed. Aperture shortly ovate, 

 but slightly oblique. Peristome continuous, shortly free above, 

 moderately thick and broadly flaring, reflexed, excavated at the 

 sinulus. Superior lamella marginal, subvertical, continuous with 

 the spiral lamella, which penetrates to the middle of the ventral 

 side. Inferior lamella deeply receding, subvertical within the last 

 whorl, a little thickened below, not extending inward as far as the 

 superior lamella. Subcolumellar lamella deeply immersed. Prin- 

 cipal plica strong, approaching the lip, extending slightly past the 

 middle of the lateral position. Upper palatal plica short, oblique, 

 slightly disconnected from the lunella. Lunella dorso -lateral, 

 straight above, curving far inward below. 

 Length 14.3, diam. 3.5 mm. 

 Clausilium narrow, rounded at the apex. 



Goto, Hizeu. Types No. 82,956, A. N. S. P., from No. 818 

 of Mr. Hirase's collection. The locality was incorrectly given as 

 Goto, Uzen, in my preliminary description. 



This species recalls (7. subaurantiaca somewhat. The lip is 

 unusually developed. The slight notch between the lunella and 

 the short upper palatal plica is unlike the allied species, and re- 

 minded me at first of some species of the group of C. sublunellata, 

 but the strong inward bend of the lower end of the lunella shows 

 clearly that it belongs to the group of C. awajiensis.

Shell fusiform, moderately solid, the penultimate whorl widest, 

 preceding and last whorls a little narrower, those above tapering to 

 a somewhat obtuse apex. Brownish -yellow, somewhat transparent. 

 Surface brilliantly glossy, as though varnished, showing some faint 

 growth wrinkles under a lens. Whorls 7-8, moderately convex, 

 the suture often appeariDg margined by transparence. Last whorl 

 not differently sculptured. Aperture subvertical, squarish-ovate. 

 Peristome expanded and narrowly reflexed, hardly thickened, the 

 upper margin adnate or barely free from the preceding whorl. 

 Superior lamella compressed, marginal, continuous with the spiral 

 lamella, which does not reach quite to the middle of the ventral 

 side. Inferior lamella deeply receding, a little thickened near its 

 lower end, straightly ascending, not penetrating as deeply as the
