APPENDIX IV. 
a young bird, and, as it comes nearest to the Bengal Roller of Latham, it is 
so considered. 
ISo. 7. Coracins afral Varl 
This Dr. Latham appears to have considered as a variety of Coracius 
afra, his African Roller, which I have not seen ; but from his account of it, 
it must vary considerably. The bill is of a brownish horn colour, rather 
more than an inch and half long, very much and abruptly forked at the tip, 
and having the edges of each mandible narrowed in. Length of the bird 
about \2\ inches ; the lower part of the neck, behind, the back, and part of 
the scapulars, reddish brown, w ith a tinge of olive green : the chin, front, 
and eye-brow white, as in No. 6 ; a small spot of w^hite also on the back 
of the head: the feathers from the bill, and on the crown of the head, are 
long and pointed, and appear capable of being erected into a crest. On 
the fore part of the head is a slight tinge of the colour of the back, but 
the predominant colour of the head, neck, and all the under parts is 
a fine rufous lilac, plain on the head and nape, but streaked with 
w^hite down the shafts on the other parts : the rump and tail coverts 
above and below partake more of violet ; a faint lilac just tinging the 
thighs and under coverts of the wings. The smaller wing coverts above 
are of a bright glossy lilac, which in the greater coverts is rather more 
mino-led with brown, so as to reduce its splendour; the ridge of the wing 
and greater quills of deep blue, which toM^ards the tips becomes greenish ; 
the margins of the inner webs and the very tips are black ; the two middle 
feathers arel dingy green, the rest blue, shading into black on the inner 
webs ; the tail itself is square at the end : the legs are strong and pale, 
claw^s brown. I am not quite decided about this bird, but it is evidently so 
nearly allied at least to Cora: afra, if not a variety of that bird, that I cannot 
venture to separate it, especially as I have not seen the latter. 
No. 8. Bucco Saltii. Abyssinian Barbet. 
As this bird appears to me evidently of a species hitherto undescribed, I 
have ventured to annex to it the above name, and am happy in the oppor- 
tunity of thus paying a merited compliment to the public exertions of its 
discoverer, while I at the same time express my own sense of his kindness, 
for the liberal communication of his collection of Abyssinian birds. The
