52 LIZARDS AND SALAMANDERS OF CANADA. 



nature. The phenomeiiii presented are opposed to what must 

 follow from cross-breeding, which might be expected in the 

 case of two closely related varieties, especially when one is 

 very rare. 



I have made no experiments with this variet}' to ascertain to 

 what its coloration may be due and what its real relations to 

 erythronotus are; but the subject is so interesting from a scientific 

 point of view that it ought to be investigated. Ontario (Macoun); 

 Hudson Bay Territory (Smithsonian Institution). 



P. cinereus erythronotus (Ireen. 



Common throughout the Maritime Provinces, Quebec, Ontario, 

 and westward to the prairies. Indeed this variety is so uniform 

 in character and abundant under favorable conditions that it 

 may be regarded as characteristic of Eastern Canada. Nova 

 Scotia, MacKay; P. E. Ii^land, Vaawart and Cox; Ontario 

 (Macoun). 



P. intermedius l^aird. 



This salamander appears to represent the last on the Pacific 

 slope. It is, however, very rare; few specimens are known to 

 science, and I was unable to procure even one for study. Hence 

 I have no personal knowledge of the species. Vancouver Island 

 (Macoun). 



P. glutinosus (ireen. 



Exceedingly rare in the southern j-art of New Brunswick, 

 which marks the northern limit of its distribution. Old lists 

 ascribed it to Nova Scotia, but no mention of its occurrence 

 there is made by recent writers. It is also credited to Ontario, 

 but Professor Macoun has not been able to collect it in that 

 province. 



Spelerpes Uafinesque. 



Tongue free all round attached by a mere pedicel and capable 

 of considerable protrusion. Digits long, slender and well
