3. Descriptions or Six New Species or Birps oF THE SuB- 
FAMILY FoRMICARINZ. By Puitip Luriey Scuater, M.A. 
(Aves, Pl. LXX.—LXXIV.) 
1. Myrmeciza Ltevcaspts, Sclater. (Pl. LXX.) 
Supra cinnamomea, subtus alba; vitta laterali utrinque ab angulo 
oris ad ventrem descendente mgra; lateribus corporis cum 
ventre imo crissoque olivascenti-cinnamomeis ; rostro nigro, man- 
dibula inferiore, nisi basi, alba; pedibus pallidis; orbitis nudis. 
Long tota 5:5; ale, 2°8; caudze 1°8. 
Hab. In Peruvia, Chamicurros ; in Nova Grenada; et Rio Negro, 
Cobati. 
The first specimen of this bird that came into my possession seems 
by its make to be a Bogota skin. 1 have lately obtained a second 
from the MM. Verreaux of Paris, marked ‘Peru.’ But a more 
satisfactory locality is Chamicurros, on the Huallaga, one of the con- 
fluents of the Peruvian Amazon, whence Mr. Gould has lately received 
several examples, along with many other interesting birds. Mr. 
Gould’s specimens were collected m the month of October, 1852. 
Male and female, so labeled, are coloured alike, and noted, ‘ Irides 
red, skin around the eyes and legs light blue.’ My Bogota skin, 
and one in the MM. Verreaux’s collection, have the base of the 
interseapularies light fawn-colour, forming a large blotch, which, 
however, as is often the case in the birds of this sub-family, is only 
to be seen when the feathers are raised. 
A specimen of this bird in the British Museum is from Cobati, on 
the Rio Negro. 
The upper plumage of the Myrmeciza leucaspis is. wholly dark 
cinnamon-colour, and divided from the pure white of the lower sur- 
face by a black band. The wing-feathers are blackish within ; the 
twelve rectrices are wholly darkish cinnamon-red. The white of the 
lower surface narrows as it descends, terminating in a point, and 
leaving the sides of the belly and crissum dusky olivaceous cinnamon- 
colour. 
2. MyrmecizaA MARGARITATA, Sclater. (Pl. LXXI.) 
S Cinereus, subtus dilutior, ventre medio crissoque albescentibus ; 
alis caudaque nigris, rectricum apicibus albis ; remigibus secon- 
dariis et alarum atque caude tectricibus superioribus omnibus 
maculis magnis, rotundis, albis terminatis. 
2 Fusco-brunnea; subtus pallide cervino-rufa; maculis alarum et 
caude clare cervinis neque albis. 
Long. tota 5°3; alee 2°8; caude 1°'8. 
Hab. In Peruvia, Chamicurros. 
My examples of this curiously marked bird were obtained from 
the MM. Verreaux, and are from the same locality as the preceding 
species. Mr. Gould’s collection from Chamicurros likewise contains 
specimens of both sexes. | 
The round spots, which render this bird a very recognizable species, 
are placed in the wing-coverts at the apex of each feather. In the
