260 CRYPTOLOPHA VORDERMANI. 
NOTE XXXVI. 
ON TWO NEW SPECIES OF BIRDS FROM JAVA 
AND CELEBES, 
BY 
J. BUTTIKOFER. 
Amongst a number of very valuable birds from the 
East-Indian Archipelago, lately presented to the Leyden Mu- 
seum by Dr. A. G. Vorderman, I found a specimen which 
proofs to belong to a new species of Cryptolopha and which 
I propose to name after its discoverer, the meritorious or- 
nithologist of the Malay Archipelago: 
Cryptolopha Vordermani. 
Very closely allied to C, Schwaneri (Blyth) from Borneo , 
but differing from the latter in having only the anterior 
half of the crown olive-gray instead of the whole crown. 
Above lively yellowish green, somewhat yellower on rump 
and upper tail-coverts, hind neck, nape and posterior half of 
the crown like the back, in contrast with the anterior half, 
which is gray ; quills and wing-coverts earthy brown, the lat- 
ter and the secondaries edged with the color of the back; tail 
brown, the outer webs edged with olive-green, especially 
on the basal half, the inner webs edged with fawn, sides 
of face and ear-coverts gray like the fore-head, lores black, 
a white superciliary streak, running from the nostrils above 
the eye, rather more developed than in C. Schwaneri, chin 
and throat pure white, rest of under surface bright yel-
