head has already told us in his book of the constant warfare 

 waged by the hill-tribes against all kinds of ground-game. 

 This accounts for the scarcity of the new Arboricola ery- 

 throphrys of Kina Balu ; and there can be little doubt that 

 the Hamatortyx, if it ever were plentiful^ is now an ex= 

 treraely rare bird, or Mr. Whitehead would certainly have 

 met with it. The structure of the feathers of the rump and 

 upper tail-coverts in Hcematortyx is remarkable and worthy 

 of special notice. The feathers of these parts (see figure, 

 p. 376) are rather long, and have the basal half of the shaft 

 very wide and flattened. Aljout halfway from the base the shaft 

 becomes abruptly contracted, the terminal half being extremely 

 fine and pliant. The same form of feather, but less strongly 

 marked, characterizes the Argus and Peacock Pheasants, and 

 there is a slight indication of it in Rollulus, while in Calo- 

 perdix the shaft is normal. In no other species of game-bird 

 is this peculiarity so strongly marked as in Hcematortyx. 

 The synonymy of this bird stands as follows : —
