PATAGONIAN EXPEDITIONS : ZOOLOGY. 



A similar band proceeds from the base of the upper mandible across the 

 sides of the face below the eye. 



Neck : Grayish. The two buffy white face streaks prolonged down- 

 ward on the upper neck. Each feather of the gray parts of the back of 

 the neck has a dusky median stripe, and on the under neck each feather 

 has in addition two paler buffy stripes laterally and numerous obscure 

 dusky cross bars. 



Back : Grayish, profusely banded and spotted, with dusky or black and 

 pale fulvous, the latter spots being round, well defined and conspicuous. 



Wings : Primaries blackish, spotted on the outer web and barred on 

 the inner web with light buff, or white with a buffy tinge. The second- 

 aries are barred on both webs. 



Tail : Dusky, barred with darker or black and also with white with a 

 strong buff tinge. 



Lower parts : Generally buffy white, marked with many blackish cres- 

 cent-shaped bars, except on the abdomen which is almost uniform in 

 color. "Bill blackish," feet bluish gray (Sclater). 



The sexes are similar in appearance and color. 



Geographical Range. Southern South America, from southern Uru- 

 guay, throughout western Argentina and Patagonia. 



The Princeton Expeditions did not meet with this species and the above 

 description is from material in the British Museum, and from three speci- 

 mens in the Princeton University Museum cited in detail below. 



The British Museum has lately acquired a series of males and females 

 of this species from Colhue-huapi, Chubut; collected, from July 22 to 

 August 9, 1902, by J. Koslowsky. 



Mr. Barrows says of the "martinete " (a term applied in Spain to a heron 

 or its plume. Here it undoubtedly refers to the long feathers of the crest), 

 that unlike the species just described, this one is always found in small 

 parties, and usually running in single file. In the neighborhood of Bahia 

 Blanca it was not uncommon, but it was not elsewhere met with, being 

 confined pretty rigidly to the shrubby country bordering the pampas on
