C. VARIA, Sowb. PL 54, figs. :}8-41. 



Longitudinally narrowl>' ribbed, decussated by revolving lines 

 which are often more or less obsolete except towards the base of 

 the body-whorl ; marbled with chestnut or chocolate and white, 

 sometimes almost covered with the darker color, but always 

 having a more or less defined central white band, which some- 

 times reappears at the sutures of the spire-whorls ; outer lip of 



aperture ribbed within. Length, 1 inch. 



Piinama. Mazatlan. 

 This appears to be the shell which Carpenter described as 

 Anachis (? costellata, var.) pachydermata. C. Hcalarina^ Sowb. 

 (fig. 39) is a state of this species in which the whorls are unusually 

 shouldered, C. veleda, Duclos (fig. 40), and C. ophoaia, Duclos 

 (fig. 41), are both synonymous with C. varia^ the latter with the 

 shouldered variety. 



C. CRUENTATA, Morch. 



An unfigured species, said to generally resemble C. daliola, 

 Duclos (= C. varia, Sowb.), but with longer spire, and smaller, 

 broader aperture. The characteristic coloring consists of blood- 

 red spots, usually upon altei'nate ribs, some in the interspaces of 

 the ribs ; some specimens have only a single red spot, others are 

 entirely white. Length, 6 mill.

C. LYRATA, Sowb. PI. 54, fig. 42. 



Shell sharply longitudinally ribbed, decussated by revolving 



striae, which are frequently obsolete except at the lower part of 



the body-whorl ; yellowish, articulated by two bands of chestnut 



spots appearing on the ribs ; aperture Avhite ; lip sinuated behind, 



plicate within. Length, 18-22 mill. 



Panama. 

 C. FULVA, Sowb. PI. 54, fig. 43. 



Shell reddish brown, with distant narrow longitudinal plica- 

 tions, fading out at the lower part of the body-whorl, where they 

 are replaced by revolving striae. Length, 23 mill. 



Panama, uuder stones, 



C. Terpsichore, Sowb. PI. 54, figs. 44-46.
