ask what I think of P. crassulus. I have given the question 

 some thought and I am of the opinion that it is a uniform color 

 phase holding- the same relation to P. intermedins (with which 

 the type agrees structurally and not with P. oregonensis) as P. 

 cinereus does to P. crythronoHis" 



P. crassulus may, therefore, be regarded as a synonym of 

 P. intermedins. I think one Is justified in doubting that the 

 original specimen really was collected in California. 



7. Plethodon croceater Cope. 



This salamander also was described from a single specimen 

 said to have been sent to the National Museum by John Xantus 

 from Fort Tejon, California. This specimen was No, 4701 

 of the National collection. It seems to have been lost, for Dr. 

 Stejneger writes me that it has not been or? the shelves in 

 his time. As in the case of P. interniediiis, "there seems orig- 

 inally to have been some trouble with the series of entries to 

 which these belong, as apparently by some mistake two collec- 

 tions were given the same numbers. First there is an entry 

 in an unknown hand in black ink and under there is an entry 

 in Prof. Baird's handwriting thus: 



"4701 Rana Chiloweyush Dr. C. B. Kennerly 



Heredea Fort Tejon — 1 — Xantus 



" 4732 Scotophis gutatus Micanopy, Fla. Dr. Bean 



" occidentalis Ft. Tejon Xantus 



"The ditto mark [under Scotophis] refers to the line above, 

 which is Plethodon, and this Plethodon, No. 4731, is a Pletho- 

 don cinereus from Detroit, Dr. Sager." 



It is evident that the locality Ft. Tejon is "exceedingly du- 

 bious." Plethodon occidentalis is evidently a manuscript name 

 for P. intermcdius. 



Cope has recorded Plethodon croceater from Cape San 

 Lucas, Lower California, and San Diego, California, both of 

 which localities need confirmation. The former locality may 

 have resulted from the association of the original specimen 

 with John Xantus, who collected both at Cape San Lucas and
