THE CROCODILES AND LIZARDS OF BORNEO. 97 



secondaries and tail, much darker and richer ; some of the outer 

 webs of the inner primaries also chestnut ; under-parts much 

 purer white ; thig-hs buff, not blue like those of P. pyrrhopterum. 



This species was obtained in the jung-le not far from 

 Kuching-. 



In describing" this new bird, I considered it advisable to give 

 a short diag-nosis of the two older and well known forms, of 

 which this museum contains a fine series. 



In referring- to Mr. Sharpe's description of P. pyrrhopterum, 

 (vol. iv., p. 365), I find that he says the " wing-s and tail, chestnut" 

 in the young male, but at page 366, he states that " the quills and 

 tail-feathers are dusky blackish on the inner web, greyish blue 

 externally " ! I have examined all our specimens carefully and 

 cannot find a trace of the latter colours on the tail-feathers ; and 

 certainly no greyish blue on the primaries. 



I have much pleasure in naming this new species after the 

 Hon'ble F. R. 0. Maxwell, Resident of Sarawak.
