34 HELICEA. 



Say changed his opinion of the identity of this species 

 and V. pellucida, subsequently to the publication of Long's 

 Expedition. Among his notes, kindly furnished me by 

 Mrs. Say, is a description of it under the name of Helico- 

 limax canaliculata. The description was never published. 



Stimpson (1. c.) observes, " This being a boreal species, 

 occurring in Greenland, it is probable that it is identical 

 with the European one to which it was referred by Mr. 

 Say."

In Chemnitz, PfeifFer, and Deshayes, S. ca?npestris Gould 

 is erroneously quoted as a synonym of this species. 



Bishop Elliott discovered in the old cemetery at Savan- 

 nah a variety, distinguished by a beautiful golden apex 

 and uniform amber color. 



Authentic specimens of this species are still preserved 

 in the collection of the Philadelphia Academy of Natural 

 Sciences. 



SUCCINEA INFLATA Lea vol. ii. p. 66, pi. Ixxx. fig. 11. 



Having examined the original specimen of this shell in 

 Mr. Lea's cabinet, I am inclined to doubt its specific 

 weight. I have, however, had an outline of his specimen 

 figured, and propose to leave to the future the question of 

 its identity with S. campestris Say.
