CAM^NA. 269 



More elongated and slender than C. brachyodon, and lacking the 

 basal tooth. Some specimens of C. arata approach adusta in shape, 

 but they are more coarsely sculptured. 



C. OBLONGA Sowerby. PI. 18, figs. 10, 11, 12. 



Shell perforated, oblong, subcylindrical, thin, brownish, subrugose. 

 Spire more or less elongated, the apex rather obtuse. Whorls 5 -6, 

 convex, the last much shorter than the spire. Aperture subvertical, 

 oblong-oval, livid inside; peristome expanded, subreflexed, the col- 

 umellar margin broadly dilated, nearly closing the umbilicus.

 ured inside. (Pfr. t from Cumingian specimen.)

 ogr. ii, p. 78 ; Conchy 1. Cab., Bui., p. Ill, t. 34, f. 9, 10. 



Seems to resemble C. adusta closely ; not seen by me. The 

 locality requires confirmation.

Shell pupiform, umbilicated, solid. Buff, with two broad reddish- 

 chestnut bands on the body-whorl, with an umbilical patch of the 

 same color, and a narrow band bordering the suture below, and 

 ascending the light colored spire. Whorls 5-5 i, convex, the last 

 rounded, finely malleated throughout. Aperture slightly oblique, 

 oval-truncated ; lip reflexed, white.
