PTBBOCLDEUS SENEGALENSIS ERLANGERI '295 



To the above I may add a few average measurements taken from 

 the made up skins of over 100 specimens. Wing 7'15 inches 

 (= 181'6 mm.), bill at front, from tip to feathers on forehead 

 •52 (= 13'6 mm.). 



Colours of Soft Parts. — " The feet and bill vary from pale slaty- 

 grey to pale-plumbeous, or lavender-blue ; the irides are dark-brown 

 and the orbital skin pale lemon-yellow to pale yellowish-green." 

 {Hu?ne.) 



Adult Female. — Whole of upper plumage rather dull buff, some- 

 times sandy-buff, sometimes vinaceous and sometimes with here and 

 there a slightly rufescent tinge ; the feathers of the crown and nape 

 are marked with central longitudinal spots of dark-brown which form 

 regular streaks, on the hind-neck the spots widen into blotches and 

 on the upper back become broad bars, the centre wider and pointed ; 

 the feathers of the rest of the upper parts are barred ; scapular?, 

 innermost secondaries and lesser and median coverts like the back, 

 but the feathers broadly tipped with buff and some of the coverts 

 very finely edged with reddish-brown ; remainder of wing like the 

 male, but with fewer reddish bars on the median coverts. Chin, 

 lores, supercilia, sides of the head and throat yellow- ochre, the 

 sides of the head speckled with blackish-brown, these spots in- 

 creasing in size on the neck and breast, which are like the back, but 

 generally with a stronger vinaceous tint ; the chin and throat are 

 immaculate in old birds, but the ear-coverts have fine black hair- 

 marks. Most females have a faint indication of a very dark brown 

 line separating the upper breast from the lower, which is a dull 

 pale ochre-buff; abdomen, flanks and feathers of vent rufous-buff 

 closely barred with very dark brown, under tail-coverts creamy- 

 buff. Tail-feathers like those of the male ; axillaries and under 

 aspect of wing brown, the smaller coverts and shoulders barred with 

 dull-buff. 



As already shown above, the birds grade in general tone from 

 a sandy-buff to a dull vinaceous-buff above and on the under plumage 

 they vary to much the same extent. The upper breast in some 

 specimens may be quite a dull, almost brown tint, whilst in other 

 birds it may be quite a pale sandy-buff ; most birds will, however, be 

 found intermediate. The light unspotted lower breast also varies in
