APPENDIX IV.

when on the ground in its native deserts, the bird is with the utmost diffi- 
culty to be distinguished. About the eyes, the chin, and throat, the fea- 
thers are whitish, as are also the lower part of the belly, vent, thighs, under 
wing coverts, base of the prime, and tips of the secondary quills ; on the 
belly and vent there is a slight shade of cream colour ; and across the 
upper part of the breast is a kind of band of a much lighter shade than the 
back, narrowly dashed down the shafts with brown. The scapulars and 
upper wing coverts, are of a light dusky brown, edged "and tipped with sandy 
white; the two outer of the primary quills being dusky, and the third, for near 
an inch from the base, margined on the outer web with whitish, and having 
a large white spot on the inner web ; the rest are white across both webs 
at the base, and the last is deeply margined all round the tip, but princi- 
pally on the inner web, with brownish white : . the two first quills are of a 
much lighter dusky than the others; the secondaries are dark dusky, white 
at the base, margined outwardly and deeply tipped on both webs, so as to 
form two bars across that part of the wing when it is spread, which appear 
like small spots when the wings are closed. The two middle feathers of 
the tail are of a very light dusky brown, deeply margined with the same 
sandy colour as the back ; the rest are of a dark dusky tinge, the exterior 
w^eb of the outermost feather being almost white : the legs and feet are of 
a very pale yellowish white, and the legs, particularly, partake very much 
of a calcined look ; the claws are of a pale horn colour, and the hind 
claw is rather short, strong, and slightly bent, with the end whitish." 
I have greatly to regret that occupations of a more serious nature pre- 
vented his Lordship from completing this list, but, as he has favoured me 
with drawings of No. 55, which I conceive to belono;' to a new oenus, I have 
given a plate of it, under the name ofErodia amphilensis, for the informa- 
tion of the reader. At the time we first saw this bird at Amphila, it struck 
us all as a very uncommon one, being perfectly unlike any other we had 
seen before. With this I shall conclude my remarks respecting the birds 
of Abyssinia. 
The only insect which I have thought particularly worthy of notice is the 
Abyssinian locust, as I understand from one of our best informed naturalists
