 East Africa, Madagascar, Mauritius, Ceylon, 



Philippines^ New Caledonia. 



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

 revolving punctured grooves, obsolete in the middle ; yellowish

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. Weinkauif.
