This variety closely connects C. magus with C. consors. C. 

 Tasmania, Sowb. (fig. 13), is a somewhat more highly colored 

 specimen of this variety, and C. epistomoides, Weink. (fig. 14), 

 differs but little. 



C. PERTUSUS, Hwass. PI. 16, figs. 15-17. 



Spire convex, rather obtuse, body-whorl encircled by distant 

 punctate striae ; rosy tinged with yellow and interruptedly 

 banded with white blotches below the shoulder and in the middle 

 of the body-whorl. Length, 2 inches. 



Madagascar, Mauritius, Philippines, Ins. Annaa, etc. 



C.festivus, Chemn. (fig. 16), = am,abilis, Lam., is synonymous. 

 C. inquinatus, Reeve (fig. 17), appears to be merely a darker 

 colored specimen, chocolate-brown instead of roseate. 



C. SIMPLEX, Sowb. PI. 16, fig. 18. 



Shell oblong, turbinated, rather thin; white, with longitudinal 

 irregular chestnut streaks. Length, 2 inches. 



West and South Africa. 



The spire is more elevated, the body-whorl more cylindrical, 

 the color-markings more continuous than in C. spectrum yet it 

 may be a variety of that species. C. informis, Dillw., is a 

 synonym. 



C. rudis, Chemn., is scarcely determinable from the original 

 figures, and neither Sowerby nor Reeve has attempted to 

 identify it. Dr. Weinkauff, however, adopts it as a species, and 

 refers to it, G. informis, Dillw., C. elongatus, Sowb., Thes. 

 (part), f. 241, and C. inquinatus, Reeve all of which differ 

 utterly in form from the Chemnitzian figures. 



C. SINDON, Reeve. PL 16, fig. 19. 



Shell somewhat ventricosely turbinated, nearly smooth ; white, 

 very thickly decussated with exceedingly fine reddish brown 

 lines in such a manner as to form two broad transverse bands ; 

 spire rather obtusely convex, apex rose-tinted. 



Length, 1*25 inches. 



Habitat unknown. 



I am not acquainted with this species, of which only a single 

 individual is known ; it was described from the cabinet of Mr. 

 Adamson, of Newcastle, England, and Dr. Weinkauff, apparently
