Mr. P. L. Sclater on new species of American Ant'Thrushes. 877 



of feathers on the sides of the head. Trusting to Tschudi*s identifi- 

 cation of a specimen collected by him, which is now in my collection, 

 I had considered it to be d'Orbigny's C ardesiaca. But upon exa- 

 mining the type of that species in the French National Collection I 

 found such was not the case. That bird does not possess the chest- 

 nut-brown cap or darker cinereous colour of the throat belonging to 

 the present species, but is more uniform in its colouring both above 

 and below. 



There is a specimen of this bird in the British Museum from Bo- 

 gota. 



M. O. des Murs, in the Ornithology of the Voyage of Castelnau 

 and Deville, has described and figured another Conopophaga, some- 

 what resembling the present, C. peruvianay pi. 16. f. 1. But this 

 bird has spots upon the wings and a varied back. 



3. Hypocnemis elegans. 



Hypocnemis ?, Sclater, P. Z, S. 1855, p. 147. 



I have lately seen other specimens of this bird, and have one in 

 my own collection — a Bogota skin. Though closely allied to H. me- 

 lanostictUy I cannot consider it otherwise than specifically distinct, 

 and therefore propose a name for it : I have already given its cha- 

 racters in the Proceedings of the Zoological Society for 1855.

There are single specimens of both sexes of this bird in the Bri- 

 tish Museum, which are the only examples I have yet seen. It 

 may be best arranged near Myrmeciza loricatay the type of the genus, 

 with which it agrees generally in form, although the tail is compara- 

 tively much shorter.
