Variation — The three adult specimens are identical in struc- 

 tural characters and coloration. No. 29101 is a young sala- 

 mander measuring 28mm. from snout to anal opening, with a 

 tail 14mm. long. It is like the three adults in the number of 

 its costal folds and general coloration, except that the dorsal 

 band is bright pink clouded on the head and along the mid- 

 dorsal line with dark brown. This brightly colored band ex- 

 tends from the snout, along the back, nearly half way down the 

 tail. This specimen looks very much like P. intermedins, but 

 the lower surfaces are darker. 



Remarks — While this new species is manifestly closely re- 

 lated to Plethodon intermedins and P. vandykei, it can easily 

 be distinguished from both by the greater number of its costal 

 grooves and the greater space between its adpressed limbs. 

 The number of costal grooves is 16 in all four specimens of 

 the new species, while in Plethodon vandykei these grooves are 

 12 and 13, and in P. intermedins they are 13 or 14. 

 Plethodon intermedins is of inore slender build, with longer 

 toes, more truncate snout, and less dusky coloration. The 

 paratoid gland and webbed feet of P. vandykei are characters 

 which should render its recognition easy. 



5. Plethodon intermedius Baird. 



This salamander was originally described from one speci- 

 men said to have been secured by John Xantus while stationed 

 at Fort Tejon, California. So far as I know, with the ex- 

 ception of the type of Plethodon crassidns, this species has 

 never since been found in California, although it is common in 

 western Oregon and Washington. I have felt that the type 

 could not have been collected by Xantus near Fort Tejon, but 

 must have been so recorded through some error. With this
