248 PATAGONIAN EXPEDITIONS: ZOOLOGY. 



face, the cheeks and lower throat, all of which are streaked with brown- 

 ish black. The chin and upper throat are white, and the fore neck is 

 ashy grey with a bluish shade, the feathers being fringed with dusky. 



Geographical Range. Chili, Bolivia and Peru, extending southward 

 into Patagonia in the Cordillera to the upper waters of the Rio Chico de 

 Santa Cruz, latitude 49 south, longitude 72 west. 



The naturalists of the Princeton University Expeditions to Patagonia 

 met this species of quail-like plover at the head waters of the Rio Chico 

 de Santa Cruz, where a single bird was secured on 20 February, 1897 

 P. U. O. C. 9 adult 7779. This extends materially the known habitat of 

 T. oribignianus, bringing it well into the Patagonian territory. It will 

 doubtless be found common at points in northern Patagonia and in 

 southern Patagonia at least as far south as indicated. Mr. Hatcher in 

 speaking of it in his manuscript field-notes says: "Occurring in coveys 

 of from 10-20 on the high pampas near the coast. Of similar habits and 

 distribution to the former." ("Former" here refers to Attagis gayi. ) 



Two examples of this species have been collected by J. Koslowsky, in 

 the Valle del Lago Blanco, Chubut district, in November and December, 

 1901. This appears to be the first record of the bird in this locality. 

 They are both males and are fully adult.
