Mr. P. L. Sclater on new species of American Ant-Thrushes. 377 



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 cuiereous colour of the throat belonging to 

 the present species, but is more imiform 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 Casteluau 

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

 what resembling the present, C. jier^iviana, pi. 16, f. 1. But this 

 bird has spots upon the wings and a varied back. 



3. Hypocnemis elegans. 



Hypocnemis ?, Sclater, P. Z. S. 185.5, p. 147. 



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

 my own collection — a Bogota skin. Though closely alhed to 77. me- 

 lanosticta, I cannot consider it otherwise than specifically distuict, 

 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 loricata, the type of the genus, 

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

 tively much shorter. 



5. FORMICIVORA H^MATONOTA. 



Supra brunnea, dorso medio rubro, hoc colore uropygium versus 

 dilutiore : alarum tectricibus nigris, omnibus macula terminali 

 pallide cervina prceditis, secundariarum externarum apicibus
