“Tris hazel or chocolate; bill, upper mandible corneous, 
lower pinkish horn ; feet wax yellow, ranging to orange.” 
Fairly widely distributed up to about 5,000 feet, but 
nowhere at all common. 
Like other members of the subgenus Avachnoraphis, the 
males are very considerably larger than the females, having 
the wing 108-111 against 94-104 in the latter sex.

“Tris chocolate or hazel, bill black, paler horn at base of. 
lower mandible, feet greenish black.” 
There is some confusion with relation to the forms of 
this subsection Avachnoraphis, inhabiting the Malay Peninsula 
and the Indo-Malayan Islands. 
In 1846, Miiller and Schlegel described two species 
A. robusta and A. armata, the types of both species coming 
from Indrapura on the West Sumatran coast, about fifty 
miles in a straight line from the localities where the above 
listed specimens were secured. 
A. armata differed from A. vobusta in its smaller size, 
especially in the bill and in the darker throat and chest, 
which is much greyer and in the less yellow abdomen. The 
figures given do not, however, bear out these differences. 
Finsch ‘loc. cit.) and Buttikofer, also consider that the 
species have a separate existence, while Hartert (Nov. Zool. 
vill, p. 52 (1901) ), working on a series of recently collected 
birds from Java, shows that the birds from this island are
