The history of the nomenclature of this variety or quaM-peeies 

 is .-oinewhat complicated. It was at first confounded hy l>oth Lin- 

 meiis and Lamarck with the Polynesian form, which differs in 1 

 somewhat more coarsely striate with a carinate periphi -r\. 8 

 .|iient authors, in distinguishing the species, liave restrict. -d 

 marck's species to the West Indian form, notwithstanding the sig- 

 nificance of his name for it, and the fact that the only figure !

 Linn. I have concluded to adopt for the present variety (lim-lin's 

 name, which appears to me to have been clearly intended for it.
