Adult. “Iris chrome, bill lead, cere greenish, feet lemon 
yellow.” 
Immature. ‘Iris yellow, feet chrome, toes brighter, 
claws black, bill black, slate at base, cere and gape greenish.” 
In all, three or four specimens of this little Sparrow Hawk 
were seen, either in the open torrent-swept gully in the vicinity 
of our camp or in the heathlike zone above the forest at 
heights exceeding 10,000 feet where they probai 13: fed on the 
ouzel so common there. aos 
The adult bird exactly agrees with thé description, 
dimensions and plate of A ccipiter vufotibralis from Kinabalu as 
given by Sharpe, loc. cit. supra 1889, the under tail coverts 
being erroneously stated to be chestnut in the original descrip- 
tion: and both have the 4th and 5th primaries practically 
equal, whereas the 4th is decidedly the longest in all speci- 
mens of A. v. gularis and A. v. affints which we have been able 
to examine. Grant categorically states that the adult females 
of A. v. gularis are barred up to the throat, whereas all the 
immature specimens from Malaya in the F.M.S. Museums 
have these parts distinctly longitudinally striped, thus resemb- 
ling the Himalayan form, A. v. affinis; their dimensions, 
however, the wing not exceeding 7.7, would place them with 
A. v. gularis, with which Grant (loc. cit.) has identified 
numerous specimens from “ Malacca.” It should be stated 
that the majority of our specimens have been obtained on 
migration mostly on Pulau Jemor, a small island in the middle 
of the Straits of Malacca and have not improbably come south- 
wards from Burma and Pegu. Given sufficient material it 
‘ will probably be found that the hawieneeatas group are 
divisible into races as follows :— 
A. virgatus virgatus, Java, Borneo, Sumatra and 
Malay Peninsula. 
A. virgaius gularis, China and Japan south-west- 
wards through the Philippines and Malay Archipelago 
to the Malay Peninsula in winter where it meets the 
succeeding form. 
A. virgatus affinis (Hodgs.’. Himalayas and Assam 
south-westwards in winter through Burma as far as 
Pegu (not reaching the Malay Peninsula) where it 
meets the preceding form. 
A. virgatus besra (Jerd.) South India and Ceylon; 
Andamans ? 
A. virgatus confusus WHartert (A. manilensts auct., 
nec. Meyen), Philippines. 
It would appear that the forms A. v. gularis and 
A. v. affinis are migratory, ranging south in winter, while the 
others are sedentary. Judging from the dimensions given 
by Sharpe for birds from Sumatra and Java (Stray Feathers, 
vill (1879), p. 441), we believe that A. rufotibialis is a synonym
