the low marshy places. Mr, Elliott, of Charleston, South Carolina, 

 since favored Ifao with living specimens from near that city, where, 

 he informed me, they are not very abundant. These individuals 

 refused such vegetable food as I could procure for them, (in 

 December,) but one of them devoured the animal of a Helix which 

 was in the vessel that contained them. Lister's figure above 

 quoted is referred to with doubt by Ferussac, in his Tab. Syst. p. 

 57, for his Helix goniostoma. 



In Lesueur's collection are specimens which he found at St. 

 Francisville on the Mississippi, and Mr. Titian Peale found speci- 

 mens on the Florida Keys. So that, taking the above-mentioned 

 localities into consideration, this shell seems to be an inhabitant 

 of the whole alluvial region, from at least the middle of South 

 Carolina to the Mississippi, and perhaps even still farther south. 



In the American edition of Nicholson's Encyclopaedia T pub- 

 lished an account of this species under the name of Polyphemus ^_ 

 glans ; I supposed it to be that species, as Montfort says it lives in Sfi^ >/<^ 

 the interior of Louisiana. But Ferussac says that our shell is not /^ 

 the glans of Bruquiere, which is not an inhabitant of Louisiana, 

 but of St. Domingo. In his general observations, as well as in a 

 letter to me, he says it is the Buccinum striatum of Chemnitz, and 

 Bulirnus striatus of Bruquiere ; whereas, in his enumeration of the 

 species, he rejects the name of striatus entirely, and places those 

 two synonyms under two separate species, to which he gives new 

 names. I think, however, that this name cannot, in justice to 

 Muller — from whom Bruquiere adopted it — be applied to our spe- 

 cies, inasmuch as he had reference to the South American species. 

 As it is, therefore, neither the glans nor the striata, I adopt the 

 name applied byGmelin,for which I am indebted to the synonyms 

 collected by Ferussac, on whose accuracy and opportunities for 

 comparison in this instance I wholly rely, when, in my own opinion, 

 the reference would, but for this authority, be doubtful.
