ORNITHOLOGY. 



cinereous of the under parts, and also in the fulvous portion of the 

 quills at their bases being less extensive and not so conspicuous. In 

 the female (the specimen of which, now before us, was brought from 

 the Sandwich Islands by Dr. J. K. Townsend), these fulvous markings 

 form a transverse bar obliquely across the folded wing, and the under 

 parts of the body are nearly white. The tarsi are long, with the scales 

 in front large, but very obscurely defined. This bird much resembles 

 in general form several of the species included by the Prince Bona- 

 parte in his genus Taenioptera (Cons. Av. p. 165), but is different in 

 color from any with which we are acquainted. We have, however, 

 for the present, placed it in this genus. 



This interesting bird is represented in our plate the size of life.

This remarkable little species appears to have been singularly over- 

 looked by naturalists until described by Kittlitz, as above. It appears 

 to be one of the most common birds of Chili, being brought in almost 

 every collection from that country. 



The specimen in the collection of the Expedition is in adult plu- 



* "Plumage very soft and open in texture ; crest, crown, and checks black, the frontal 

 feathers having a slight margin of white; back of the neck cinereous; back olive-gray; 

 throat and breast white ; abdomen pale-yellow, the feathers lineated along the centre with 

 black; vent and under tail-coverts pale straw-color; wings dark olive-brown, the pri- 

 maries, secondaries, and tertials edged with dirty white; tail slightly rounded, bipartite, 

 and composed of twelve feathers of an olive-brown color, excepting the two outermost, 

 which have the outer webs white; bill and legs black ; irides white. 



"Total length, four and one-fourth inches; extent of wings, five and five-eighths 

 inches; wing, from the carpal joint, two and two-tenths inches; tail, one and nineteen- 

 twentieths of an inch ; tarsi, seven-tenths of an inch ; middle toe, including the claw, 

 half an inch ; claw, three-twentieths of an inch ; hind toe, four-tenths of an inch ; claw, 

 two-tenths of an inch ; bill, three-tenths of an inch ; to the corner of the mouth half an
