 mentions a report of its occurrence on Sanihel Island. It ascends 

 decidedly further on the west than on the east coast. The .-hells 

 collected hy Ileiupliill are \\ hite wi t h the apex and columella pink, 

 la>l one or t\\o whorls with a hroad yellow /one 01- two, and some- 

 times numerous yellow ish-olive lines toward the end of the last whorl. 

 Simp-oii mentions them as either pure white or slightly marked with 

 greenish or l>rown line.- on the body-whorl. It occurs in ahundance. 



It will he nh\ ions from the foregoing thai certain color-patterns are 

 locally re-tricted ; hut until many more of (lie keys are explored and 

 ample -erics collected with data on the station-, etc., no definite con- 

 clusions on the distribution of the color-varieties can lie formulated. 

 The exact hahitats of some form-. Mich as the anllilux of Say, are 

 unknown.
