Figures and descriptions. Scbl. a 1, cl] Kaup hi] Sharpe 2. 
Adult male. Similar to the adult male of A. rhodogaster, hut the cheeks vinaceous-cinnamon 
with a grey shade (instead of dark grey), chin and throat whiter vinaceous, the dark 
bars on the wing below much narrower and absent on the distal 40 mm of the 
wing, no bars distinguishable on the outermost tail-feather, the others also more in- 
distinct ([cJ*] ad. Banggai Id., V — YIH. 95, Nat Coll. — 0 14627). 
Female. Very much larger than the male. Differs from the female of A. rhodogaster by 
having the bars on the wing [and tail much narrower, those on the outermost tail- 
feather partly obhterated; cheeks vinaceous grey ([§] ad. Peling Id. V — VUE. 95: 
Nat. Coll. — C 14502). 
Immature. The under parts as in the adult male ; above with the rufous. Kestrel-like plumage 
of the young, varied with the slate-grey feathers of the adult ([q^ ] Banggai, V — VIII. 
95 : Nat. Coll. — C 14626).

Distribution. Sula and Peling groups; Sula Besi (Bernstein a I, c 1, hi)] Banggai (Nat. 
Coll.), Peling (Nat. Coll). 
Schlegel did not admit the validity of this local species in 1873 (c 2), 
but it was again upheld by Sharpe (2), and after examining the type, we agree 
with the latter in holding the two forms distinct. It is a very rare species in 
collections. Gnrney (3) once remarked that the type appeared to be the only 
specimen extant in any collection; there was, however, a second in Darmstadt 
(hi)] five are now known. The young one discribed by Kaup at the same 
time as that of this species is probably either A. ruhricollis Wall, or A. hiogaster 
S. Mull., as is pointed out by Schlegel (cl) and Salvador! (d 1). A. sulaensis 
varies geographically in Sula in the same manner as Spilornis rujipectus sulaensis. 
11. ACCIPITER VIRGATUS (Temm.). 
Jungle Sparrow-hawk. 
This species apparently consists of the following subspecies: 
1. The typical Accipiter virgatus. 
a. Falco virgatus Temm., PI. Col 1823, Nr. 109 (Java).
