It will appear from the above synonymy that I have 

 separated H. avara from this species. Other species may 

 also be included in auriculata Binney, but I make no in- 

 quiry concerning them, as my friend Mr. Bland will soon 

 publish an elaborate article on this group. 



Ferussac's (pi. 50, fig. 3) var. minor is quoted as a variety 

 of auriculata by Pfeiffer, in the first volume of his great 

 work, but in volume third is doubtfully referred to uvu- 

 lifera. 



I have specimens measuring 16 millimetres in diameter. 

 They are from St. Augustine, Fla., the only locality, in- 

 deed, from which I have received the true auriculata^ the 

 smaller variety from the keys being probably H. uvulifera. 



The shell is carried on the animal in a manner quite 

 different from that of the other species, the axis being 

 quite horizontal.

I have already remarked that the confusion existing con- 

 cerning this and the preceding species is about to be recti- 

 fied by Mr. Bland. I will, therefore, refrain from making 

 any remarks at this time. 



The species as it now stands has been found from 

 Georgia to Texas; in some of the intermediate States 

 the individuals are extremely numerous.
