This species is very closely related to C. dimidiata Smith, 

 from which the very concave cohimella (more like that of 

 C. burnupi), separates it.

Shell long-ovate, rather thin, covered with a glossy, yel- 

 lowish-olivaceous cuticle, here and there ornamented with 

 darker streaks, yellow at the suture, and girt about the middle 

 of the last whorl with a dark belt. Whorls 8, slightly con- 

 vex, the upper ones granulate, the last elongate, smooth, 

 striated with slightly oblique growth-lines, slightly descend- 

 ing in front. Aperture inverse-auriform, pale bluish within, 

 opalescent, half the total length of the shell. Columella 

 rather straight, obliquely truncate in front, covered with a 

 thin whitish callous. Length 71, diam. 39, aperture 35 x 18 

 mm. (Smith).

"This is a rather slender species, in general proportions 

 somewhat resembling Reeve's representation of Bulimus 

 Thompsoni (Conch. Icon. pi. 24, fig. 158). It is moderately 

 thin and clothed with a yellowish-olive glossy epidermis, ex- 

 hibiting at short intervals oblique streaks of a darker tint and' 

 close to the suture becoming decidedly yellow, so that the 

 upper edge of the last whorl appears to be bordered with 

 that colour. The three uppermost volutions, which have lost 

 the epidermis, are pale brown ; all the whorls except the last 

 are sculptured with spiral and oblique striae, forming a rather 

 fine granulation. The body-whorl is rather long and orna- 

 mented only with lines of growth which are well marked and' 

 slightly puckered at the suture. A faint band is noticeable 

 just above the middle, and several other transverse lines- 

 parallel with it are also observable on close inspection.
