CERION, GROUP XH. 



O. abacoense bendalli P. & V., Proc. A. N. S., Phila., 

 332, ph 11, f. 13. v 



The exceedingly short umbilical chink shows that this forpi 

 probably related to G. abacoense, rather than to the group of C. 

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

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

 men about two-thirds grown is toothless. (Named for Mr 4 Wilfred 

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



C. GRUNISRI (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 10J 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 

 Pfeiflfer'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. G. martensi is hardly 

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

 G. 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.
