Vol. VI] VAN DENBURGH— CALIFORNIA SALAMANDERS 219 



in mind I wrote to Dr. Stejneger to inquire whether the rec- 

 ords of the National Museum would throw any light on the 

 matter. He has very kindly investigated these records and 

 writes that "there seems originally to have been some trouble 

 with the series of entries to which these belong, as apparently 

 by some mistake two collections were given the same numbers. 

 The locality Ft. Tejon looks to m.e exceedingly dubious, 

 though, of course, it does not mean only the immediate neigh- 

 borhood of the old fort." A copy of the old record is printed 

 here under that of Plethodon croceater; see remarks under 

 head of that species. 



Seventy specimens of Plethodon intermedius from Oregon 

 and Washington show costal grooves as follows :

6. Plethodon crassulus Cope. 



The question of the identity of this salamander was raised 

 by the comparison of Plethodon intermedins and Plethodon 

 elongatiis. Plethodon crassulus was described in 1886 by Cope 

 from one specimen in the U. S. National IMuseum, and was 

 said to have been collected in California by Dr. J. G. Cooper. 

 Cope says that "this species has a superficial resemblance to 

 the P. oregonensis, but its manifold differences are easily per- 

 ceived." He also states that the form is quite robust, but his 

 cuts show a salamander similar in size and proportions to 

 P. intermedius, and his description fits that species in every 

 detail, for some specimens of P. intermedius show the dorsal 

 band very indistinctly. The type of P. crassulus is No. 9447 

 of the National Museum collection. In response to my request 

 for information regarding it Dr. Stejneger has very kindly 

 written me as follows : 



"The record of 9447 is dated November 20, 1877, is in 

 an unknown hand, and is blank as far as name is concerned. 

 Locality is given as California, collector as Dr. Cooper. You
