222 CERION, GROUP VI. 



C. SCULPTUM (Poey). PL 29, fig. 67. 



Shell deeply rirriate, cylindric-ovate, solid, dull whitish: sculptured 

 with strong, wide-spaced, equidistant ribs and closely decussated with 

 spiral stria. Apex obtuse, conic. Whorls 8, rather flat, narrow, 

 the last somewhat ascending in front, compressed at base. Aperture 

 semi-oval, tawny within, having a parietal and a columellar lamella ; 

 peristome somewhat thickened, broadly expanded, white, the margins 

 joined by a parietal callus. Length 22, diam. 11 mill.; apei ture 

 with peristome 9^ mill. long. (Poey}. Habitat unknown. 



Pulpa sculpta POEY, Memorias sobra la Historia Natural de la 

 Isla de Cuba, ii, p. 30, pi. 2, f. 22 (1856). Pupa sculpta Poey, 

 PFR., Monogr., iv, p. 656. 



Close to the smaller specimens of mumio, but differs by the spiral 

 striae. There are 18 ribs on the last whorl. 



This species is known by Poey's description and outline figure 

 only. The short, stout contour reminds one of the Bahaman species. 

 The locality is unknown. 



In vol. viii of the Monographia Heliceorum, Pfeiffer reduced this 

 species to a synonym of C. mumia, a course which Arango has fol- 

 lowed, but which I think is quite erroneous. 



C. SUEYRASI Blanes' Pils. and Van. PI. 29, fig. 68. 



Shell cylindrical, solid, rimate, the lower three whorls of about 

 equal diameter, those above forming a rather short, obtuse cone. 

 Whorls 10, the first smooth, next finely costulate, the rest very con- 

 vex, coarsely and sharply ribbed, the ribs rather high and angular, 

 15 to 19 in number on the penultimate whorl; numerous rather ir- 

 regular spiral striae revolving about the middle of the lower two or 

 three whorls, obsolete in some specimens. Color (of specimens some 

 time dead when collected), creamy or fleshy white. Aperture small, 

 with small teeth ; peristome expanded, subreflexed, blunt and rather 

 thick, continued in a raised straight and rather heavy callus across 

 the parietal margin. 



Length 21, diam. 8J, length of aperture 7^ mill. 



Length 22, diam. 9, length of aperture 8 mill.
