Allied to C. sphcerica, hut the ground-color is paler, the banding 

 ni:l ; M : the lip is narrower and the columella is colored. 



Tl. 3 considerable variation in contour, figs. 91, 92 representing 

 the most depressed specimen before me. This example has several 

 :i bands on the base. The coloring of this species is not- 

 ablv varialile. The principal patterns are figured on pi. 39. 



Tin- apical whorls are generally pink ; but when they are white, 

 tin columella also is light-colored.

I m perforate, solid, globose-turbinate ; ground-color yellow, usually 

 havini: a broad brown or purple-brown zone at the circumference, a 

 pink line or a yellow band at the suture, and a streak of reddish- 

 brown back of the lip and around the columella. lAp very little 

 i-i'ffi'.ri tl, ri-ri/ limit n<l thick. 



The surface is very lightly striatulate; the banding is very vari- 

 able, but the ground-color is always yellow. Apex obtuse, buff or 

 pink. \Yhori- 5, the last a little deflexed in front. Aperture white 

 within, half-round, oblique; lip thickened, flattened, its face usually

Closely allied to ('. ilnmucuxis, differing mainly in the much 

 more narrowly rdlcxrd and much more obtuse lip. 



Th<- n-iial I'onn (li^. .SM) has a wide peripheral girdle, a sub- 



sutnral line of pink or kind of yellow, and back of the lip there is 



a broad red-brown streak. Some examples have no color-bands,
