GREY-HEADED SPARROW. 
PyrgUa simplex, Swains. 
Head and neck grey'; plumage above rufous; beneath whitish; 
wings and tail brown. 
The only true Sparrow we hare yet received from 
Senegal has been found by Dr. Riippell in Abys- 
sinia, and is that which he informs us has been 
described by Professor Lichtenstein under the name 
of Fringilla simplex; he also informs us that the 
two sexes are always alike, but for this assurance 
we were certainly disposed to consider our bird as 
the female of the crescent sparrow, Pyrgita areuala, 
figured on the PL Enl. 230. 
There is not the slightest difierence, in point of 
structure, between this species and our own do- 
mestic sparrow ; even their size are as nearly equal 
as possible. In both species the tail, as in all the 
true finches ( Fringillinm ), is moderately long and 
divaricated ; the four first quills equal and longest ; 
the lateral toes of the same length, and the tarsi 
elevated. 
The colours are very simple ; the head and neck 
are uniform light grey, becoming cream-coloured 
white on the throat and breast, but there is a stripe 
under the chin as pure as the white of the body.
