290 Notes on Lingual Dentition of Mollusca. 



the Sheboygan specimens are also recent, as well as those from 

 Lexington, Virginia, and that the species, though, perhaps, rarer 

 than formerly, is still to be found in the "Western States. 



Those persons not having access to Doughty's Cabinet of 

 Natural History will be interested to know that Heliclna rubella 

 was found on hills not far from Pittsburg, Pa., on the old post 

 road from that place to Wheeling. Dr. Green received it from 

 a friend, and immediately questioned its origin, but was assured 

 that it had been actually found living on more than one occasion. 



We presume that Prof Kirtland (Ohio Eeport) refers to the 

 same individuals as received by Dr. Green, when he speaks of a 

 species of Helicina being found on the hills adjacent to the Ohio 

 river. 



Mr. Say described Helicina occulta from fossil specimens from 

 a bluff near New Harmony, Ind. He did not notice it living, 

 nor has any author done so. The name occurs, indeed, in sev- 

 eral catalogues of Recent Species, but we have never known it to 

 be found with the living animal until now.

here described is one of the original lot received from Cali- 

 fornia, from which the species was described. It was labelled 

 by Mr. Lea.
