90 CONUS. 



chocolate, interrupted by triangular white spaces ; these last are 

 irregularly disposed, but crowded at the shoulder, base and 

 middle so as to form bands ; spire similarly marked ; aperture 

 white. Length, 2'5-3 5 inches. 



Mauritius, Red Sea, Ceylon, Japan, Philippines, 



Australasia, Viti Islands, etc. 



The synonymy includes G. vicarius, Lam. (fig. 95), G. scriptus, 

 Sowb. (fig. 96), in which the reticulations cover most of the 

 surface. 



Yar. TELATUS, Reeve. PL 29, figs. 91, 98. 



The triangular reticulations much finer than in the type. In 

 a specimen before me the usual three bands are each divided 

 into two, with narrow intervening spaces. Another slight modi- 

 fication of pattern of coloring is C. tigrinus, Sowb. (fig. 98). 



Yar. VERRICULUM, Reeve. PL 29, fig. 99. 



Shell shorter and proportional^ wider than the type ; the 

 triangular white markings are usually larger and cover more of 

 the surface. Approaches the preceding species, C. retifer. 



Yar. EUETRIOS, Sowb. PL 30, fig. ] 00. 



Shell finely reticulated with chocolate lines over the white 

 surface, as to cause it to appear a uniform chocolate-color at a 

 distance, crossed by three broad bands of darker color. 



Approaches C. Elisse, Kiener. 



Yar. ARCHIEPISCOPUS, Hwass. PL 30, figs. 1-3. 



Shell smaller than the type, with much smaller reticulations, 

 more completely covering the surface. Connected with textile 

 by intermediate stages. (7. canonicus, Hwass. (fig. 2), does not 

 appear to be essentially different, and C. rubescens, Bonnet, and 

 C. Madagascariensis, Sowb. (fig, 3), may also be placed here. 



Yar. CONDEXSUS, Sowb. PL 30, fig. 4. 



Shell narrower than the type, connecting with C. auratus. 



Yar. LEGATUS, Lam. PL 30, fig. 5. 



Shell small and rather narrow, with strong longitudinal choc- 

 olate markings over the reticulations. This is essentially a 

 young state of G. canonicus, above, into which it passes with 

 growth.
