 Hab. Cordilleras of Peru, near Lake Titicaca (Meyen); Salinas 

 above Arequipa ( Whit el y') ; Laguna of Cucullata above Tacna (^Fro- 

 been). 



This Duck was first discovered by Mej-en, who obtained specimens of 

 it on the high cordillera of Peru, near Lake Titicaca. Meyen's name 

 (oxyptera) having been wrongly applied to the next species, Philippi 

 and Landbeck (as was pointed out by us in 1867) redescribed the 

 bird in 1 863 under the name angustirostris. Their specimens were 

 obtained by Frobeen, on the Lake of Cucullata, in Southern Peru. 



Our examples of this species were collected by Mr. Whitely on the 

 salt lake of Salinas, situated at an elevation of 14,000 feet above 

 Arequipa. Mr. Whitely subsequently procured other examples on 

 the lagoon of Tungasuca and on the river near Tinta, in the district 

 of Cuzco.
