The brilliant golden yellow colour of the fur which is occasionally found replacing 

 the common white and black, and from which the specific names ^' fulva ^^ and 

 ^'fulgens " have been derived, is not restricted to this species, but appears in about 

 the same proportion among specimens of other species of both Fhyllorhina and 

 RUnolophus. I have expressed my opinion^ that this golden yellow colour is ana- 

 logous to the breeding plumage in birds, and that it is restricted to females during 

 the breeding season. However, during the second Yunnan Expedition, Dr. Anderson 

 obtained several males of this species, in the same cave, all of which possessed this 

 golden yellow colour, while males and females obtained at the same time in adjoining 

 caves were of the common black and white kind. These very differently coloured 

 animals differed, however, in no other respect, agreeing in structure in all respects 

 and in measurements. The conditions under which this remarkable difference in 

 colour occurs are, therefore, still unexplained, but the golden yellow colour may be 

 developed equally in males and females when the sexes come together, which may 

 not occur at the same season for all. 



As Fh. fulva can be distinguished from Fh. hicolor by its larger ears only, I am 

 unable to consider it more than a sub-species of Ph. hicolor, Temm.

Head very slightly elevated above the face line ; muzzle obtuse ; ears narrow, 

 tapering, with rounded tips ; outer side flatly emarginate immediately beneath the 

 tip for about quarter its length, then slightly convex ; lower down opposite the base 

 of the tragus with a small emargination, terminating beyond this in a small rounded 

 lobe ; tragus long, narrow, and acutely pointed ; inner margin straight, outer 

 slightly convex upwards with a small rounded lobe at the base. 



Peet very small ; toes two-thirds the length of the whole foot ; tail wholly 

 contained within the interfemoral membrane ; wings from the base of the toes.
