98 PYGATHRIX 



Specimens from the Coromandel Coast are much grayer than 

 those from Ceylon, these being a vinaceous brown above. Whether 

 these differences in color indicate the existence of a race separable 

 from the typical form, would require more examples than are at 

 present available to determine satisfactorily, and the problem will have 

 to remain for Indian Mammalogists, who are on the ground, to solve. 



Blyth described this species as having a high, compressed vertical 

 crest, but Anderson (1. c.) has stated that the crests of specimens in 

 the Calcutta Museum were produced artificially, in one case by cotton 

 wool placed beneath the skin, and in another by a wire, in both cases 

 the result of unskilled taxidermy. 



On the other hand Blanford states in a footnote, that in three 

 dried skins from Ceylon in the British Museum, the crest was dis- 

 tinctly shown, and that he had also seen it in skins from Southern 

 India and he was assured by Davison and others that it was constantly 

 present. 



The type of P. thersites came from Ceylon and agrees with other 

 individuals from that island considered the same as P. priamus.
