262 BIRDS OF THE 



Jflotacillidae. 



230. Ilenicurus horneensis. 



Henicurus borneensis Sharpe, Ibis 1889, p. 277; Everett, L. B. Born, 

 p 100. 



A small number of this species were collected on the 

 western slope of the Liang Koeboeng, near my station 

 »Poenan-grot",at an altitude of 700 — 800 meter, and another 

 at a less considerable height on the Liang Gagaug (800 m.) 

 south of Nanga Raoen. — Iris dark brown, bill black, 

 feet (claws included) rosy white. 



This Bornean representative oi the genus Henicurus stands 

 between the very closely allied H. Leschenaulti (Vieill.) from 

 Java and H. sinensis Gould from China. From the first it 

 differs by the shorter and posteriorly rounded white crown- 

 patch, and from the latter by the narrower tail-feathers 

 which are broadly tipped with white like in H. Leschenaultij 

 while in H. sinensis they show a rather narrow, oblique 

 terminal bar. Curiously enough the reddish wash on upper 

 and under tail-coverts, recorded by Dr. Sharpe in his 

 diagnosis of the Bornean species, is entirely wanting in all 

 my above-mentioned specimens, these parts being pure white. 



A young female (nearly full-grown) has the top of the 

 head uniformly colored with the back ; chin and upper 

 throat are white with a slight fulvous tinge, while chest 

 and breast are sooty brown with white shaft-streaks. 



As to the habits of this bird I have nothing to add to 

 what is told by Mr. Charles Hose (Ibis 1889, p. 277). 



Hab. Central, North-Western and Northern Borneo.
