462 bulletin: museum of comparative zoology. 



Hahn, in a second paper, in 1908, (Notes on the mammals and cold- 

 blooded vertebrates of the Indiana University Farm, Mitchell, 

 Indiana,) states that "None were noted, however, of the so-called 

 crythronotus variety with the red of the back bordered by parallel 

 lines, but the dorsalis variety with an irregular line of red along 

 the back was almost as common as the ashy-colored individuals . . . 

 these have the sides and dorsum of the tail mottled with gray and 

 brown, caused by the segregation of the gray sjDecks into certain 

 areas." This does not accord with the dark phase of P. cincreus as 

 it is met with in the east. 



These are all the records I have been able to find of this salamander. 

 It apparently is restricted to a region including western Pennsylvania 

 and southwestern Ohio, southern Indiana, and central Kentucky. 



True P. cincreus is not known from Kentucky as yet. It is found 

 in Ohio, Indiana, Illinois, Missouri, and xA.rkansas, to the north and 

 west and in eastern Tennessee to the southeast. 



It apparently occurs with P. dorsalis in Ohio and Indiana. I think 

 it more in accord with our knowledge of the two forms at present to 

 regard P. dorsalis as a distinct species. 



53. Plethodon ctnereus (Green).
