C. GUBERNATOR, Hwass. PI. 26, figs. 68, 69. 



Whorls of the spire oarinate, channeled and striate, tessellated 

 with chestnut ; body-whorl pink-white, longitudinally clouded 

 with chestnut or chocolate, often obscurely two-banded ; several 

 distant sulci towards the base. Length, 2*5-4 inches. 

 East Africa, Madagascar, Mauritius, Ceylon, 



Philippines, New Caledonia. 



C. terminus, Lam. (fig. 69), is described as having a less 

 rounded shoulder, is narrower, etc. ; but in the series before me 

 the transition forms make a series of stages so complete that I 

 cannot separate C. terminus even as a variety. 



C. BOIVINI, Kiener. PI. 28, fig. 70. 



Spire depressed, channeled ; bod3^-whorl with equidistant 

 revolving punctured grooves, obsolete in the middle ; yellowish 

 white, with two light brown bands, and a few hieroglyphic mark- 

 ings. Length, 2-5 inches. 



East Africa (Weinkauff). 



C. MELANCHOLICUS, Lam. PI. 28, fig. 71. 



Shell elongated, rather cylindrical, cancellated with exceedingly 

 fine striae ; orange-red, with a band of white spots at the shoulder 

 and another below the middle of the body-whorl ; spire smooth 

 and sharp, spirally striated, variegated with orange-red. 



Length, 2 inches.

Australia, New Guinea, Polynesia. 



Perhaps the most beautiful species of the genus. C. cingulatus, 

 Sowb. (not Lamarck), is a synonym, and C. discrepans, Sowb., 

 a dead, colorless shell, not adult, but with the same form and 

 grooving, is referred here by Dr. Weinkauff.
