DUTCH BORNEO-EXPEDITION. 161 



from Nanga Raoen wants the blue crown-patch and the 

 red collar on the hind neck, while the yellow on the front 

 is not so deep as in adult birds and not extending over 

 the sides of the crown ; the blue color on the throat is 

 paler and less extended, and the red patches on the sides 

 ot the throat are smaller. The whole bird is much smaller 

 than the adult and even smaller than the young specimens 

 from Sumatra, and the bill much shorter, the culmen 

 measuring only two cm. instead of 2,5. Having no adult 

 male from Borneo to compare with, I dare not say that 

 the Bornean specimens as a rale have the bill shorter 

 than those from the Malay Peninsula and Sumatra. 

 Hab. Malay Peninsula, Sumatra and Borneo. 



24. Cyanops monticola. 



Cyanops monticola Sharpe, Ann. & Mag. Nat. Hist. 1888, p. 424; 

 Everett, L. B. Born. p. 168; Sharpe, Ibis 1890, p. 5. 



Two males and a female from Mount Liang Koeboenoj. — 

 Iris reddish brown, bill in male entirely black, in the female 

 the upper mandible only black, lower mandible green, feet 

 green. The males agree fully with Dr. Sharpe's description, 

 the female differs from the male in having the lower man- 

 dible green (two females from Mr. Hose's collection agree 

 exactly with mine). 



Hab. Mountain-regions of Borneo (Kina Balu, Mt Dulit, 

 Liang Koeboeng).
