CERION, GROUP XII. 267 



O. abacoense bendalli P. & V., Proc. A. N. S., Pliila., 1896, p. 

 332, pi. 11, f. 13. 



The exceedingly short umbilical chink shows that this form is 

 probably related to C. abacoense, rather than to the group of O. mar- 

 tensi, which it resembles in sculpture and color. It is here grouped 

 with the latter on account of its superficial resemblance. A speci- 

 men about two-thirds grown is toothless. (Named for Mr. Wilfred 

 Bendall, author of a list of land shells of the Bahamas.) 



C. GRUNERI (Pfeiffer). 



" Shell' deeply rimate, cylindrical, rather solid, closely plicate; 

 white, beautifully marbled with fulvous and chestnut ; plica close, 

 hair-like, nearly straight, as wide as the interstices. Apex conic, 

 rather obtuse; whorls 11, a trifle convex, the apical smooth; last 

 whorl somewhat compressed below the umbilical chink. Aperture 

 semi-oval, fleshy-livid within, with an entering parietal and a deeply 

 placed columellar tooth ; peristome expanded, reflexed, the margins 

 slightly connected. Length 29, diam. 11 mill.; aperture 10^ mill, 

 long, 9 wide" (Pfr.}. Habitat unknown (Gruner coll.).

PfeifFer's description is given above. I have identified as gruneri 

 some specimens of unknown locality (pi. 44, fig. S3) agreeing with 

 PfeifFer's diagnosis in coloration, sculpture and size. The parietal 

 lamella is continued as a low fold into a dorsal position, being thus 

 very long for this group. It is a larger species than eximium, with 

 finer riblets, and broader than marmoratum. C, martcnsi is hardly 

 distinguishable, having the same very fine, close rib-striae. Cf. also 

 (7. venustum Poey. 



C. MARTENSI (Weinland). PI. 38, figs. 73, 74, 75. 



Shell obliquely and deeply rimate, solid, oblong, closely hair- 

 striate, variegated with brownish-corneous and whitish. Spire long, 

 more ventricose above the middle, terminating in an obtuse cone. 

 Whorls 11, nearly flat, the last exceeding one-third the total length, 

 somewhat ascending in front, subcompressed at base. Aperture 

 oval-lunar, brown inside, scarcely obstructed by the minute, deeply 

 placed dentiform parietal callus ; peristome thick, reflexed through- 

 out, the margins joined by a rather thick callus ; 'no columellar fold.
