18 Birds of Celebes: Falconidae. 
A second specimen, moulting (male), is similar to tliat described, and a 
few brown feathers of immaturity among the scapulars and secondaries reveal the 
fact that the pale vinaceous under surface of this form (known as T. ciiciiloides) is 
not a result of age, but is assumed as the young dress is cast off. “Iris dark brown; 
cere orange; feet gold yellow” (cf, Kema, N. Celebes, 3. Oct. 93; P. & P. Sarasin). 
Adult in more rufous plumage: soloensis^’. Similar to the first- 
described bird, but darker slaty above; the jugulum and breast rufous, obscurely 
barred, the bars becoming more distinct on the flanks (Main, IST. Celebes, 28. Peb. 
1894: Nat. Coll. C 13239). 
A young specimen (moulting), assuming adult plumage of . the 
rufous form, has the head, neck and mantle, and single feathers on the scapulars 
and lower back, dark slate ; the wings (mpmy remiges lost), tail, and other upper parts 
in the brown plumage of the young; the breast (adult) deep rufous (Manado tua Id., 
end of May, 1894: Nat. Coll. C 13358). 
Young. Very different from the adult: above brown (instead of slaty), darkest' on head; 
below white, broadly streaked on the breast with rufous, and barred on the abdomen, 
flanks and thighs with paler rufous. ' . 
A young ' specimen — Q, Mindoro — kindly lent to us by ' Mr. Nehrkorn 
resembles Schlegel’s figure (e II), but the streaks on the breast are larger and 
broader; the upper surface more uniform; ear-coverts without any grey wash; 
head dark clove-brown — almost black. 
Eggs. Similar to those of Accipiter nisus, white with a few dark broAvn convolutions and 
blots at the small end: 39 X 30 mm (Nehrkorn in litt.).

Some strong grounds have been given for separating A. cuculoides Temm. 
from A. soloensis Horsf. as a distinct species. Dr. B. B. Sharpe {k I) distin- 
guishes A. cuculoides chiefly by its pale vinous under surface mixed with ashy, 
and pure white under vring-coverts, from A. soloensis in which these parts are 
vinous-chestnut and huffy white, respectively. The late J. H. Gurney (1) adds 
from information supplied by SAvinhoe, in whose cabinet he Avas able to exa-
