54 LIZARDS AND 8ALAMANDER9 OF CANADA. 



but I have no direct evidence that such takes place. 



The dorsal l)and is lighter in color than in more southern 

 stations. 



I am not aware of its occurrence at any other station in 

 Canada. Ten years ago I collected larvie near New Carlisle. 

 Gaspe. P. Q.. which I have since identified as belonging to this 

 species.

 it. Considering the extreme southern range ascribed to it in the 

 United States, its occurrence in Canada is somewhat of a sur-

 ones. One species at least terrestrial at one stage of develop- 

 ment. 



Diemyctylus torosus Kscb. 



This is a newt of which I have no personal knowledge, for

 to procure a specimen for study proved unavailing. It is said 

 to range from California to Alaska. Professor Macoun collected 

 it nn Vanc'Hiver Tsland. 



D. viridesceos Kartnes(iue. 



Very common in all suitable ponds and lakes throughout the 

 Maritime Provinces in all of which including Ciaspe P. Q.. the
