their apex. In other respects it partly agrees with the before-men- 
tioned example, but bears most resemblance to Gallus eneus of M. 
Temminck, although the hackles of the latter are described as “ vert 
métallique a réflets pourpres trés-éclatans,” &c. These differences 
have made it desirable to add a figure of the bird alluded to (pl. 8), 
that persons who have the means of studying these birds in their native 
places may be induced to determine whether these examples may 
justly be considered species, or only hybrids of others that are already 
known to naturalists. 
2. ON A NEW SPECIES OF THE GENUS GLAREOLA. 
By G. R. Gray, F.L.S. ere. 
(Aves, Pl. IX.) 
GLAREOLA NUCHALIs. 
Brownish ash tinged with bronze, paler on the throat and breast, 
and darkest on the quills and tail; a white line commencing at the 
gape and extending round the nape, thus forming a prominent collar ; 
the base of the tail-feathers, with the space gradually enlarging to 
the outermost, and the tips of the third, fourth and fifth feathers, 
white ; the abdomen and under tail-coverts ashy-white; the two 
longest of the latter with a broad patch near the tip of each dark 
brownish ash. 
Bill black, with the base yellow; feet yellow, with black claws. 
Total length, 54’; bill from gape, 8’; wings, 5! 7!"; tarsi, 9!"; 
middle toe, 8!". 
The bird here described was discovered by Francis Galton, Esq., 
at the fifth cataract of the Nile. This species may prove eventually 
to be found also on the Quorra, Western Africa, as is partly shown 
by an immature specimen in rather bad condition, which is contained 
in the collection at the British Museum. 
3. DESCRIPTION OF A NEW SPECIES OF THE GENUS CULTRIDES. 
By G. R. Gray, F.L.S. ere. 
(Aves, Pl. X.) 
CULTRIDES RUFIPENNIS. 
Head, neck, and breast, blue-black, tinged in some lights with green; 
the back and smaller wing-coverts olivaceous ; the greater wing-coverts 
and the outer webs of the secondaries bright cimmamon; the inner 
webs of latter and primaries dark violet ; the throat and lower part 
of breast and abdomen ashy-white ; the middle feathers of the tail 
changeable bronzy-green ; the second, third, and fourth feathers, dark 
green slightly tinged with bronze on the outer margins, the first 
feather on each side dark violet-blue. Bill black, with the tip white ; 
the legs and feet pale. 
Total length, 1’ 10"; bill to gape, 2! 4'"; wing, 72"; tail, 1’; 
tarsi, 2! 7!"’, 
This bird, which is supposed to be a native of Mexico, forms a 
second species of the genus Cultrides, which was established by M. 
Pucheran, with the Coceyzus Geoffroyi of M. Temminck for its type.
