Birds from Pueblo Viejo, Colombia. 159 



Specific diameters. Back and top of head dark olive-brown ; forehead 

 and auriculars chestnut-rufous ; wings rufous, darker on outer webs, 

 brighter on inner ; ends of primaries dusky ; upper and under tail-coverts 

 and tail chestnut-rufous ; throat buff; chest rufous, this color forming a 

 conspicuous band and extending along neck to auriculars ; center of belly 

 tawny-olive shading to raw umber on sides and flanks. 



Size.tf adult: wing, 83.2; tail, 77; exposed cuhnen, 23. 



Remarks. A. rufipectus is apparently very different from any of the de 

 scribed species, its rufous chest being distinctive. 



Conopophaga sp. ? 



One female, which cannot be properly identified at present. It has no 

 white tufts on sides of head. 



Cassidix oryzivora (Gmelin). 

 Two males. 



Buarremon basilicus sp. nov. 



Type (and only specimen), from Pueblo Viejo, Colombia. No. 5598, 

 cf adult, coll. of E. A. and 0. Bangs. Collected Mar. 21, 1898, by W. W. 

 Brown, Jr. Altitude 8000 ft. 



Specific characters. Nearly related to B. torquatus (d'Orb. & Lafr.) from 

 Bolivia, but differing from that species in gray instead of white super 

 ciliary stripe; in reddish olive instead of olive green back, rump, wing- 

 coverts, edges of tail, wing feathers, tail-coverts and sides of body ; in 

 pale fawn-color instead of white breast and center of belly ; in wider 

 black band across chest ; and in larger bill. 



Rize.tf adult: wing, 81.2; tail, 78.8; exposed culmeii, 17.4. 



Remarks. This new species is probably nearly related to B. poliophrys 

 (Berl. and Stolz.), which has the same slate-gray superciliary stripe. B. 

 poliophrys is said to be otherwise like B. torquatus, while the Pueblo Viejo 

 bird has a larger bill and many differences in color. 



Sporophila sp. ? 



One female. The species cannot be determined by this skin, which is 

 not in distinctive plumage. 



Calospiza desmaresti (Gray). 

 Two males. 



Calospiza cyanoptera (Swains.). 



Two males of the bird which I recorded in my last paper * as ' Calospiza 

 sp. ? ' on the basis of a female specimen. 



Ramphocelus dimidiatus Lafr. 

 Eight specimens, including males and females.
