This handsome species would appear to be not uncommon in Oregon. 

 I found it abundantly in the redwood forest at Russian Eiver, Cali- 

 fornia. Its eyes are [jroniiueut and beautiful in life. 



Cxirard referred this species to a genus which lie called Heredia, and 

 as it appears to me without reason, as I can find no characters by which 

 to distinguish it from Plethodon. Dr, Mivart informed me that this 

 s[)ecies was labeled as identical with the Triton ensalus Esch. in the 

 British Museum, and presuming on the accuracy of the determination 

 I called it P. ensatus. On examination of his figures I find that Eschs- 

 ciioltz's animal is very different, perhaps generically so, and probably 

 wortliy of reference to a genus Ensatina, in accordance with Dr. Gray's 

 catalogue of the British Museum, a course followed by Dr. Boulenger. 



Besides specimens in Museum of the Philadelphia Academy and Essex 

 Institute, and my own cabinet, the following have come under my ob- 

 servation :

Proceed. Ac. Nat. Sci. Phila., 1867, p. 210, I. c, 1869, p. 100; Strauch, 

 Salam. p. 70 ; Bonleuger, Cat. Batr. Grad. Brit. Mus., ed. ii, 1882, p. 55. 



The largest species of the genus, and one of the most ornamented of 

 the American salamanders. 



In primary features this species is near the P. oregonensis Girard 

 having the attachment of the tongue along the median line quite nar- 

 row, and a very narrow free margin in front. The palatine teeth form 

 two long transverse separated arcs, which are directed more poste- 

 riorly at their median than exterior extremity, the latter extending far- 

 ther outside the outer margin of the inner nares than the transverse 

 diameter of the same. The tail is subcylindrical and slender; conr
