Remarks. — In its upper plumage this species is much like 

 ■E. subpaga?ia, also in the markings on the wings, but they are 

 quite different below, K stibpagana having the throat of a clear 

 grey, and the breast and abdomen of a brighter yellow. 



6. IVIitrephoriis aurantiiventris, sp. nov.

 not showing except on those which project beyond the others on the

 with light dull olive, the innermost ones have their edges whitish ; 

 smaller wing coverts olive green, the others blackish brown, the middle

 becoming lighter, and on the abdomen and sides changing to bright

Length (fresh) 5% in. ; wing 2% ; tail 2 T 5 F ; bill § ; tarsi £. 



Habitat. — Costa Rica, Tabacales. Collected by Dr. A. von 

 Frantzius, January, 1864. 



Spec, in Mus. Smith. Inst., No. of type 39052. Another spe- 

 cimen, a male, No. 39056, killed by Dr. Frantzius in April, 

 1865, at La Palma, has the coloring below much paler and the 

 under mandible of a deeper yellow. 



Six specimens examined agree quite uniformly in plumage. 



Remarks. — This species much resembles M. phwocercus, but 

 is rather smaller, the color above is more green, but they differ 

 most in the coloring of the under plumage, M. phaiocercus being 

 below of a uniform deep reddish fulvous which is but little 

 lighter on the lower part of the abdomen ; the crest is rather 

 darker than the back, but not as decidedly so as in phmocercus, 

 in which it is olive brown ; the under mandible in the new 

 species is more yellow.
