154 ANACII1S. 



C. VARIA, Sowb. PI. 54, tigs. 38-41. 



Longitudinally narrow!} 7 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. 



Panama, Mazatlan. 



This appears to be the shell which Carpenter described as 

 Anachis (? costellata, var.) pachydermata. C. scalarina, Sowb. 

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

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

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

 shouldered variety. 



C. CRUENTATA, Moi'Ch. 



An untigured 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 alternate ribs, some in the interspaces of 

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

 entirely white. Length, 6 mill. 



8onsonate, West Coast of Central America. 



C. LYRATA, Sowb. PL 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 white ; 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, under stones. 



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



Whorls longitudinally ribbed and nodosely shouldered ; ribs 

 rather distant and narrow ; white, with revolving bands of
