As pointed out by Blanford and by S. Flower, this species 

 presents two extreme forms which one might think at first worthy 

 of specific distinction. The comparison of a large material shows, 

 however, that such a separation is not feasible. I have endea- 

 voured to keep the two distinct, regarding as the typical form 

 the ' broad-headed form ' of Flower and bestowing the name var. 

 blythii on Blyth's R. fusca (a name which is preoccupied) for 

 Flower's " narrower-headed variety." I must say the definition 

 of the latter is not very precise, as almost every character suffers 

 individual exceptions and some specimens might as well be referred 

 to the one form as to the other. Such are the characters of the 

 shape of the head, of the size of the eye and of the tympanum, 

 and especially of the extent of the web between the toes, the two
