101 AMERICAN JOURNAL 



SCIENTIFIC INTELLIGENCE. 



The genus Pupoidea, of Mr. Pease, published in this Journal 

 for January, 1866, appears to be the same as Palaina, of Mr. 

 0. Semper, of which several species have been figured in recent 

 numbers of the "Journal de Conchyliologie." 



Mr. Pease proposes to change his name Helix scidptilis, pre- 

 occupied by Mr. Thomas Bland, to Helix fratercula. 



Mr. Frank Daulte, of Cincinnati, Ohio, a zealous collector, 

 informs us that he has obtained a sinistral specimen of Helix 

 elevata. Reversed Helices are not nearly so numerous in Ame- 

 rica as in Europe, and this is the first published notice of a re- 

 versed elevata. Mr. Bland, in his " Remarks on Certain Spe- 

 cies of North America Helices," mentions that his cabinet con- 

 tains sinistral specimens of H. altei'nata, thyroides and 3Iitchel- 

 liana ; that Mr. Binney has H. fallax, Mr. Isaac Lea H hirsuta, 

 and Mr. Anthony H. injiecta and solitaria reversed. 



Mr. J. G. Anthony writes to us that Paludina scalans, Jay, 

 commented upon by us in this Journal, (p. 116, 1866,) is a good 

 epecies, as he has seen at least fifty specimens of it, none of 

 which vary from Dr. Jay's figure. He was informed by a per- 

 son who collected it, that in certain localities it occurs abund- 

 antly.
