-TXAviNG figured two or three species allied to this shell, it 

 appears advisable to subjoin a more particular notice ofit, and 

 to point out those characters by which it may be detected 

 through its numerous variations : this has been endeavoured 

 in the specific character now formed, and appears to rest prin- 

 cipally on the inner lip, which is always semicircular, down 

 which, if closely examined inside, there is a depression as if 

 it had been pared down with a knife; the base of the pillar 

 also is so strongly truncated as to appear notched, and the 

 broadest part of the mouth is always in the middle ; these cha- 

 racters have been very ill attended to in all the figures above 

 quoted, of which Seba gives no less than eleven, which vary 

 only in the disposition and number of their bands. 



Gualtieri's figure at tab. 6. Jig. D, is an admirable repre- 

 sentation o^ A. pallida, which, not having his work before me at 

 the time, I could not quote ; the other at C is a very good one 

 of the present shell. The upper drawing is from one in my 

 own cabinet; the lower is in the possession of Mr. C. Dubois, 

 who is continually adding to his fine and valuable collection. 



It is almost unnecessary to contradict the opinion of some 

 writers who have fancied this a fresh-water shell. It is not 

 uncommon, but seldom seen in perfection.
