DUTCH BORNEO-EXPEDITION. 161 
from Nanga Raven 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 em. 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;

Two males and a female from Mount Liang Koeboeng. — 
Tris 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).
