 Viv., p. 378. t. 115, f. 2. 



A well-marked form, distinct in possessing a narrow umbilicus, 

 and distinctly granose lirse.

Shell subrimate, cyclindrical-conic, smooth, shining ; whorls 8 the 

 first eroded, greenish ; the remainder scarcely convex, red and 

 white clouded, maculate with brown above, encircled by equidistant 

 olive-brown lines ; last whorl angular, convex beneath and orna- 

 mented with 6 concentric lines; aperture subquadrate, smooth 

 within ; basal margin scarcely arcuate ; columella narrow, sub-

It is possible that Ziziphinus japonicus A. Ad. is identical. 



Fischer says : This species is quite remarkable in its very elongated 

 form, like a Bankivia. Lischke's type was not adult ; it is more 

 conical and smaller than the specimen figured by me, attaining only 

 8i mill. 



C. PUPILLUS Hutton. 



Shell depressed or sometimes elevated, imperforate or narrowly 

 perforated ; whorls spirally ribbed. Dark brown or greenish-brown, 

 with brown and reddish markings ; margin of the aperture greenish-
