Collection of Birds made in Northern Somaliland. 29 7 
As the female of this species does not appear to have 
been described, I add the following description:— 
Adult female. Entire upper parts brownish-grey, the feathers 
on the mantle tipped with blackish-brown ; a broad buff 
superciliary streak ; under parts light yellowish white, washed 
with greyish on the throat and breast. 
It most nearly resembles Passer yatei Sharpe, but lacks 
the pronounced yellow band across the fore-neck. It is also 
allied to P. cinnamomeus Gould, but iu this latter species the 
upper parts are much darker and the lower back is washed 
with rufous.

a-m. ^ $ et g ? imm. Waghar, 1st July-31st Oct., 1905. 
Iris brown ; bill horn-coloured; legs and feet pale brown ; 
toes dark brown. 
Mr. Lort Phillips has separated the Somaliland bird from 
P. tristriata under the name of P. pallidior , on the ground 
that the former is very much greyer on the breast and sides 
of the body; he also mentions the dark colour of the bill as 
a conspicuous character. I have compared the series of 
birds obtained by Mr. Bury at Waghar with a series of 
P. tristriata in the British Museum, and also with Mr. Lort 
Phillips* examples from Somaliland, and I cannot see the 
necessity of separating them under different specific names; 
the colour of the breast in at least two specimens procured 
by Mr. Bury is exactly similar to that of an example from 
Abyssinia, and though in some examples from Somaliland 
the belly is certainly whiter than in birds from Abyssinia, 
there are others from that country which shew as much 
white on the lower surface as the type of P. pallidior. 
Immature birds of both races are indistinguishable.
