PTEROCLURUS SENEGALLUS 309 



Measurements. " Males. — Length 13"4 to 14'7 inches, expanse 23 

 to 23'7, tail from vent 5'3 to 6'0, wing 7'5 to 7'9 ; the wings when 

 closed reach to within 2'3 to 2'8 of the end of the longest tail- 

 feathers, viz., the central ones, which exceed the others by from 1'75 

 to 2-0, bill at front '44 to '47, tarsus I'O to 1-05. Weight 9 to 

 12 ozs." {Hume.) 



My measurements, which include those of all the skins in the 

 British Museum, average a little larger than Hume's do. Wing 

 7'50 inches (= 190-.5 mm.) to 8-20 {= 208-2 mm.) with an average 

 of 7-84 (= 198-9 mm.), tarsus -90 (= 22-8 mm.) to I'O (= 25-4 mm.) 

 with an average of -93 full (= 23-6 mm.) and bill at front 4.5 

 (= 11-5 mm.) to '50 (= 12-6 mm.) and averaging about -48 or a little 

 over (= 122 mm.). The tail is anything from 5-0 (— 127-0 mm.) 

 to about 6-6 { = 167-6 mm.) or over. " Weight up to 12 ozs." 

 (Pitman.) 



Adult female. — Whole upper plumage, including wing-coverts, 

 scapulars and innermost secondaries, isabelline of a darker, redder 

 tint than in the male ; the head is marked with fine central marks 

 of black or dark-brown, which form streaks, the rest of the upper 

 parts are boldly spotted with dark-brown or black, the spots being 

 boldest and largest and often tinged with grey on the scapulars 

 and innermost secondaries, which feathers also have broad marks 

 of chrome-yellow at the tips on the outer webs. Lores white, and a 

 faint mark of white round the eye and thence backwards takes 

 the place of the grey in the male, but is finely marked with black 

 and stops short of the nape. Remainder of under parts like the 

 male, but paler and less pink or vinaceous, and with the central 

 portion of the abdomen more decidedly brown. The wing-quills are 

 the same as in the male, and the tail also is similarly coloured. 

 On the upper plumage the colour ranges from sandy-isabelline to a 

 rufous or vinous isabelline, extremes of either colour being decidedly 

 rare. In many birds the yellow splashes on the scapulars are 

 very faint, and in a few altogether absent. In a good many birds 

 the bufi' below is almost white and is seldom at all rich ; the yellow 

 throat also is often very pale and the amount of spotting on the 

 throat and breast is by no means constant, being very sparse on 

 the lower breast in some specimens.
