their apex. In other respects it partly agrees with the before-men- 

 tioned example, but bears most resemblance to Gallus ceneus of M. 

 Temminck, although the hackles of the latter are described as " vert 

 metallique a reflets pourpres tres-eclatans," «&c. These differences 

 have made it desirable to add a figure of the bird alluded to (pi. 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.

 By G. R. Gray, F.L.S. etc. 



(Aves, PI. 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 roimd 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, vrith the base yellow ; feet yellow, with black claws. 



Total length, 5^" ; 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. etc. 



(Aves, PI. X.) 



Cultrides rufipennis.

 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
