176 REMARKS ON THE GENUS PERICROCOTU8. 



Very possibly ours are all immature. 



Our Malaccan specimens answer precisely to Strickland's 

 description. 



"Above uniform cinereous; front whitish; lores black; 

 remiges blackish, the medial portion of their inner webs white ; 

 the 5th* to the 9th* primaries, and all the secondaries with a 

 sub-basal white bar on the outer webs ; rectrices blackish, 

 largely tipped with white ; chin and lower parts white. L., 8 ; B. 

 at f., 0-458 ; to g., 0-75 ; W., 3*75 ; Med. Rectr., 3-5 ; Exterior 

 do., 1-5 ; Tarsus, 0*66 ; Mid-toe and Claw, 0-66." 



To this I should only add that the tertiaries and later second- 

 aries are generally more or less narrowly margined on their 

 outer webs towards their tips with white, and the secondary 

 greater coverts tipped with white. That the ear-coverts are 

 nearly concolorous with the back ; that the sides and flanks are 

 shaded cinereous ; and that the white of the wing bar of the 

 axillaries and wing lining, are in some specimens more or less 

 tinged (in one female before me conspicuously so) with yellow. 



A male has the wing 3 - 8. Three females, measured in the 

 flesh, varied as follows : — 



L., 7-82 to 80; Ex., 10-62 to 1125; T., 4-0; W., 3*65 to 

 3-76; Ts., 5 to 0'6 ; B. fr. g., 0*8. 



These four specimens were killed in November. 



But our eight Tenasserim specimens, also killed in November, 

 December and February, all differ in some important respects 

 from the Malaccan birds. 



In the first place they are smaller, the bill conspicuously so 

 in most cases. 



A male has the wing 347. Seven females, measured in the 

 flesh, varied as follows : — 



L., 7-5 to 7-75 ; Ex., 10-6 to 11-0 ; T., 3-75 to 3'82 ; W., 3*5 

 to 3-62 ; Ts., 0-5 to 0-6 ; B. fr. g., 072 to 075. 



Then whereas the rump and upper tail-coverts are, in the 

 Malaccan specimens, cinereous uniform with the back ; in all 

 the eight Tenasserim specimens these parts are a pale fawn or 

 whity brown, contrasting with the back and somewhat like, but 

 not so brightly colored as, these parts in P. cantonensis. This 

 latter, however, apparently altogether wants the wing bar in 

 the male, and in the female has the whole of the upper parts 

 lighter and browner ; the quills edged with yellow, and the light 

 part of the tail feathers a rather bright yellow. 



Generally the upper surface of our bird is browner and less 

 grey than in modestus, and the breast and sides are much 

 overlaid with pale earthy brown. 



* Strickland does not couut the 6mall or bastard primary.
