MACROCERAMUS, HAITI. 119 



Distinct by its peculiar chain-like markings. Figures 65, 

 66 represent \vell-marked specimens from Tortola. Figs. 67, 

 68, 69 are Anageda shells, which differ from the typical form 

 in being paler, and less closely marked. The specimens from 

 Anguilla are similar to those of Anageda, the one figured 

 (fig. 70) being more distinctly marked than most of those 

 before me. 



This Species is the Bulimus cylindrus of Gray in Turton's 

 Manual, but not the B. cylindricus of his earlier description, 

 which was probably M . formosus.
