110 THE JUNGLE BUSH-QUAIL, 



specimens it is scarcely traceable. Moreover, the supercilium, 

 such as it is, in the Rock Bush-Quail is immediately above the 

 eye and ear-coverts, whereas in the Jungle Bush-Quail the long 

 supercilium is separated from both eyes and ear-coverts by a 

 narrow band of the same rich chestnut as the throat. 



Besides these differences, there is in the males of the Jungle 

 Bush-Quail a well-marked yellowish white rictal stripe running 

 under the eye and ear-coverts, while in the Rock Bush-Quail 

 there is only a faint trace of a pale line. 



The black bars on the lower surface of the Jungle Bush- 

 Quail are far more regular and better marked than those of the 

 Rock Bush-Quail. Indeed, in this latter species, it is only on 

 the neck and breast that they are at all regular and continuous, 

 while in the Jungle Bush-Quail they are regular and continuous 

 almost to the vent. 



In the females of the Jungle Bush-Quail there is only a trace 

 of the rictal stripe. The young males resemble the females, 

 but have the rictal stripe well marked. At first the breast and 

 abdomen is the same dull rufous, faintly suffused with grey, as 

 in the adult female ; then the tips of some of the feathers be- 

 come yellowish, then a dusky line appears above this tip, then 

 the tip becomes whiter, the line becomes a dark bar, and above 

 this a pale bar bounded by a dark line begins to show ; lastly, 

 the tips and bars become nearly pure white and blackish brown, 

 and the rufous disappears entirely, except about the vent, thigh- 

 coverts, and lower tail-coverts. These parts, I may note, are 

 always rufous in the Jungle Bush-Quail, and a kind of pale 

 dingy sandy hue in the Rock Bush-Quail. I have also re- 

 marked that in this latter species there are almost invariably 

 more or less distinct bars on the lower tail-coverts, whereas in 

 the former species these are (in all the specimens I have seen) 

 entirely without any trace of bars. 



I may add, that in one stage of the quite young Jungle Bush- 

 Quail, the feathers of the cheeks, of the throat, sides of the 

 breast and interscapulary region are very conspicuously white 

 shafted — a feature which I have failed to observe in any of my 

 specimens of the Rock Bush-Quail. 



Again, as a general rule, the tertiaries aud scapulars in the 

 Jungle Bush-Quail are very conspicuously blotched with black, 

 and also usually have conspicuous yellowish white to reddish 

 buff shaft stripes, both of which are almost entirely wanting, 

 or at most are but feebly reproduced, in the Rock Bush-Quail. 

 But too much stress must not be laid upon this, because it only 

 really suffices to separate nearly adult up to middle-aged birds ; 

 since in very old specimens of the Jungle Bush-Quail these 

 blotches almost entirely disappear, while in quite young birds 

 of the Rock Bush-Quail these blotches are pretty conspicuous, 

 though not nearly so much so as in the corresponding stage of 

 the Jungle Bush-Quail.
