by minute white spots, and overlaid by larger white triangular 

 spots, sometimes forming bands at the shoulder, middle and 

 base. Length. 2^3 inches. 



Red Sea, Ceylon, Philippines, Australia, Polynesia. 

 With this species I am compelled to unite G. pennaceus, Born 

 (figs. 20, 21), C. prselatus, Hwass (fig. 22), C. episcopus, Hwass 

 (figs. 23, 24), C. rubigmosus, Hwass (fig. 25), G. magnificus, 

 Reeve (fig. 26), and G. stellatus, Kiener (fig. 2*7), the latter a 

 juvenile. 



Yar. COLUBRINUS, Lam. PL 31, fig. 28. 



Shell rather narrower, marked like C. textile, with longitudinal 

 chocolate streaks, the triangular white spots fewer and smaller. 



C. AULTCUS, Linn. PL 31, figs. 29, 30. 



Shell rather narrow, with elevated spire; chocolate-brown, 

 covered by elevated close revolving lines of darker color ; sur- 

 face irregularly overlaid by subtriangular white spots, some of 

 which are very large. Length, 3'5-5'5 inches. 



Mauritius, Ceylon, Philippines, N. Caledonia, 



Viti Isles, etc. 



Distinguished by its form and revolving raised lines, and the 

 absence of white articulations. 



C. AUBATUS, Lam. (fig. 30), is distinguished only by a redder 

 color and occasional minute white spots on ,the revolving striae ; 

 it is scarcely entitled to a varietal name. 



Undetermined and Spurious Species. 



The following names, mostly of long standing, have not been 

 identified with any of the species by either of the monographers. 

 The descriptions are usually insufficient, and the references to 

 the plates (sometimes the figures themselves) perplexing.

LEOPARDUS, Meusch. ; C. FUSIFORMIS, Lam. ; C. LAMELLOSUS,
