Birds of Gambia. 
15 
These five species whose range should include the Gam- 
bia, I do not know at all and have no descriptions available to 
draw upon, so merely give their lengths as given in the British 
Museum Catalogue. One of them is probably the large dark grcy- 
bacued Eagle with slow flapping flight, which one sees here occasion- 
ally anl which I always imagine is one of the Harrier- Eagles 
(Circaehis) . Anoither Eagle, one of which I shot in 1905, may 
also be one of them. It was wholly dull brown with lemon-coloured 
legs and unfeathered tarsi. Length 24 inches. 
Aslurinula monngrammica. ONE-STllEAKED HAWK. 
R-anffe. Tropical Africa. (H.L.) 
This small Hawk I think I have once or twice seen. It 
is (grey above, darker on the rump, below white from chin to 
chest with a black streak down the centre of the chin and throat 
(its distinguishing feature), rest of under surface barred with grey. 
Length 15 inches. 
Mellerax polyzonus. MANY-BANDED GOSHAWK. 
Ranffe. North-east Africa, Soudan to Mogador and Sene- 
glamljia. (H.L). 
Another of the grey Hawks included in the general Mandingo 
name " Selingo." It is not uncommon in the Upper Eiveir Pro- 
vince, but I have never seen it anywhere nearer the sea. Above 
it is bluish grey, darker on the wings; the tail (which is compar- 
atively long and by which one can gienerally recoginise the bird 
when on the wing) is dark grey barred with brown abovle and 
below; the under surface is greyish white crossed by narrow bai's. 
Iris brown, 'beak black. Cere and leigts red. Length 20 inches.

Mexican Ground Thrush. 
(GeoeicJila pinicola)-. 
By Hubert D. Astley, M.A., F.Z.S., M.B.O.TJ., 
A true pair of these birds which I received on the 
12th of December are thorouglily Cieocichline in their stj^le, 
form, and demeanour, but very different in colour to their 
better known relative, the Orange-headed Ground Thrush of 
India (G. citrina). The Mexican Ground Thrush, which in- 
habits the higher pine forests of that country, nesting to a 
height of 8,000 feet, has a very pied appearance, the male 
ha\ing for his ground colour a deep umber brown on the upper 
parts, as well as on the throat and breast, the underparts 
being ashy white; and this latter colour variegates the wings 
after a Geocichlme manner, as well as the final feathehs, of the 
upper tail coverts, and the tips of the tail itself. The female
