“Alaji sasoko”, Baiiggai Id., Nat. Coll. 
Figures and descriptions. Schl. a I, cl', Kauj) b T, Sharpe 2. 
Adult male. Similar to the adult male of A. rhodogaster, but the cheeks vmaceous-cmnamou 
vfith a grey shade (instead of dark gi-ey), chin and throat whiter vinaceous, the dar 
bars on the Aving below much narrower and absent on the distal 40 mm of the 
wing, no bars disthiguishable on the outermost tail-feather, the others also more in- 
chstinct ([c^*] ad. Banggai Id., V — VTH. 95, Nat. OoU. C 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 tad- 
feather partly obliterated; cheeks vinaceous grey ([$] ad. Peling Id. V VIH. o. 
Nat. Coll. — C 14502). 
Immature. The under parts as in the adult male; above with the rufou^ Kestrel-like plumage 
of the young, varied with the slate-grey feathers of the adult ([cf] Banggai, V V • 
95: Nat. Coll. — C 14626).

Distribution. Sula and Peling groups: Sula Besi (Bernstein 
Coll.), Peling (Nat. Coll). 
Schlegel did not admit the vaUdity 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. Gurney (3) once remarked that the type appeared to he the only 
specimen extant in any collection; there was, however, a second in Darmsta 
(b 1)\ five are noiv known. The young one discribed by Kaup at t e 
time as that of this species is probably either A. rubricollis Wall or A hogaster 
S. Mull., as is pointed out by Schlegel fc 1) and Salvadori (d 1). A. sulaensis 
varies geographically in Sula in the same manner as Spilorms rujipectus sulaensis. 
11. accipiter VIRGATUS (Temm.). 
Jungle Sparrow-hawk. 
This species apparently consists of the following subspecies: 
1. The typical Accipiter virgatus. 
«. Faleo virgatus Temm., PL Col. 1823, Nr. 109 (Java> Sbarpe, Str. F. 1879,
