Ilahitat. Bogota. 



Memarhs. In the stripe over the crown and the black sides 

 of the head, this species resembles £. leucojpterus and B. pal- 

 lidinuchiis, but the stripe is uniform in color, and is paler and 

 duller than it is in B. leucopterus. The stripe in B. pallidi- 

 miclius is of two colors, being whitish on the hind neck ; in all 

 other respects they are entirely unlike. The coloring, gener- 

 ally, is dark and dull, and it appears to differ from all others 

 of the genus, in the striped character of the under plumage. 



3. I^erpophag^a g^risea. 



F Front, crown, and lores sooty black, sides of the head and the hind 

 neck grayish-fuliginous ; upper plumage of a clear grayish-cinereous ; 

 tail feathers black, tipped ^svith whitish-gray ; quills and wing coverts 

 black, the latter with very narrow edgings of dull gray; under 

 plumage and under wing coverts light ashy-gray, the throat and 

 abdomen whitish ; bill and feet black. 



Another specimen — perhaps younger — has the head rather lighter 

 in color, and the wing coverts end in pale ochreous-white. 



Length 4 in. ; wing 2 ; tail \\\ ; bill /g ; tarsi |. 



Ilahitat. Costa Rica. 



RemarTis. These two specimens were in a large collection 

 of birds, made mostly in the vicinity of San Jose, by the 

 Messrs. Carmiol, for Dr. C. H. Van Patten, from Avhom I ob- 

 tained them. 



' It differs from specimens of S. cinerea from Ecuador and 

 New Granada in being smaller in all its measurements, and in 

 having the under plumage whiter, especially on the throat and 

 abdomen. In S. cinerea the throat and breast are much darker 

 and uniform in color ; but the most marked differences are in 

 the absence of concealed white on the crown feathers, and in 

 wanting the conspicuous white terminations of the wing coverts, 

 which exist in the other species, the edges of the wing coverts 

 in S. grisea are scarcely perceptible.
