(No. 30,491.) General characters of B. ilelnttrii, but the wings much longer 

 and more pointed, nearly equal to the entire tail, which is shorter and less 

 rounded ; the 1st quill rather longer than the secondaries. There is no 

 appreciable white in the cliin ; that on the side of the lower jaw is scarcely 

 apparent, and does not extend below the chestnut cheeks. The brown of thu 

 crown does not extend so far back on the head, and hence not behind tlw 

 ears. The upper parts are of a purer olive ; beneath of a clearer yellow, the 

 crissum being unicolor with the belly. The quills and tail feathers are darker. 



Total length, 4.85 ; wing, 2.28; tail, 2.50; graduation, .24; diflFerence be- 

 tween 1st and 4th quills, .24 ; length of bill from nostril, .30 ; along gape, .55 ; 

 tarsus, .85. 



It is possible that a larger series of typical B. delattrii may show 

 that the differences mentioned above are not characteristic, and thnt 

 the Costa Kican specimens actually belong to delattrii. I think, how- 

 ever, they are really diff'erent.
