104 THE CANADIAN NATURALIST. [March 



Helix (^Punctwni) minutissimum, Lea. Same locality and 

 collector as for the preceding species. 



Notes on other Species. — Vahata humeralis (?), Say. 

 (^Can. Nat., Vol. 8, page 102.) Though this may not be the 

 true Humeralis of Say, in my judgment the shells in question 

 are perfectly distinct from any varieties of V. tricarinata, or of 

 V. siiicera. Mr. Binney refers them to the former, and the late 

 Dr. Gould, to whom I sent specimens, to the latter species. Dr. 

 Lea referred them doubtfully to V. humeralis. Our shells are 

 covered with a thickish olivaceous epidermis, and are strongly 

 transversely ribbed. 



Planorhis macrostomus. Probably it would be better to unite 

 this form, together with the PL trivolvis, lentus and corpulentus 

 of Say, under the general name of PI. trivolvis. Say. 



Helix exoleta, Say, so far as I am aware, does not occur in 

 Lower Canada. Prof. Bell's specimens, said by him to have been 

 determined by Mr. Binney, are all H. dentifera, Binney. 



Pupa simplex, Gould. The shells catalogued under this name, 

 are all Pupa badia, C. B. Adams. j. f. w. 



Lower Canadian Marine Mollusca. — Since the appear- 

 ance of my paper on dredging in Gaspe, in vol. iv., p. 270 of the 

 new series of this journal, a few species of shells, which I had no 

 means of identifying in Montreal, have been sent to Mr. J. G. 

 Jeffreys, F.R.S., etc., for identification. Having been compared 

 with specimens named by Moller, Mr. Jefi'reys recognizes the 

 following species, which must now be added to our list of Lower 

 Canadian marine molluscs : — 



Utriculus turritus, Moller. 

 Rissoa scrohiculata, Moller. 



Bela Plngelii, Moller. 

 Bela impressa. Beck. 



The shell supposed by me to be Philine lineolata, Gouth., Mr. 

 Jeffreys informs me, is Philine lima, Brown. In like manner, 

 the Margarita I referred to Gould's M. argentata, is M. Glauca, 

 Moller, sp. ; and the species queried as Diaphana dehilis, Gould, 

 is probably Utriculus hyaUnus. j. F. w. 



Swiss Mammalia. — M. Fatio gives the number of mammals 

 inhabiting Switzerland in the wild state — that is, excluding the 

 cat, dog, horse, ass, ox, sheep, and goat — as fifty-eight, or as sixty- 

 one, if the rabbit (which is not indigenous, but has been imported
