Mr. J. H. Gurney Notes 07i 
uppermost bar is imperfect. When I examined this speci¬ 
men I unfortunately omitted to ascertain whether it had the 
bases of the pectoral and abdominal feathers white; and I am 
also unable to say in what part of Africa it was obtained. 
(No. 17.) A fuliginous example from Bissao, in the Norwich 
Museum_, marked by the late MM. Verreaux as a female^ 
only differs from No. 12 in the following particulars, viz.:— 
there are no white bases to the feathers of the under surface, 
and no white tips or markings on the under tail-coverts; the 
narrow transverse markings on the tail, which agree in num¬ 
ber and character with those of No. 12, are, with the excep¬ 
tion of the whitish tip, greyer on the middle pair of rectrices 
and on the outer webs of the remaining tail-feathers; in 
the wing-linings the smaller under-coverts are wholly fuli¬ 
ginous ; but some feathers of the larger under-coverts are 
entirely a greyish white; none of the feathers in the wing- 
linings are particoloured. In this specimen many new fea¬ 
thers are appearing, both on the mantle and on the under 
surface, which entirely resemble the older feathers, allowing 
for the latter being somewhat faded. 
(No. 18.) A similar specimen from Nubia, in the Norwich 
Museum, agrees with No. 17 in all respects, except that the 
under tail-coverts are marked with white, as in No. 12, and 
the white tips to the upper tail-coverts are more conspicuous 
than in No. 17; also the colour of the narrow transverse 
bands on the tail corresponds with those on the tail of No. 12; 
several of the feathers on the underparts have been recently 
acquired, and agree in colour with the older feathers, allow¬ 
ing, as before, for some fading of the latter. 
(No. 19.) Captain Shelley^s fuliginous female from the 
Humbe, in Benguela, also agrees with No. 17; but the upper¬ 
most pale narrow bar on the tail is less perfect; two new 
rectrices resemble the older ones in their markings; but the 
pale bars on the new rectrices are grey, as in No. 17, and on 
the older ones browner, as in No. 12. This specimen is in 
moult, both above and below; and the same remark which I 
have made as to the similarity of colour in the old and new 
feathers in Nos. 12, 17, and 18 applies in this instance
