Tbe first examples of this fine Duck that attracted our notice were tbose in the gallery of the Jardin des Plantes at Paris, one of which is marked as having been obtained in the province of Cochabamba in Bolivia by D'Orbigny, and the other in Chili by Mr. Gay, the latter locality, however, being probably erroneous. The specimens were not named ; and we were at first inclined to regard them as belonging to an undescribed species. Subsequently, however, we received Peruvian skins of the same bird from Mr. H. Whitely, and were thus induced to make a more accurate examination of it. This led to the discovery that it is the species described by Tschudi in his ' Fauna Peruana' as Anas puna, from a specimen obtained by Philippi in the highlands of Peru, and transmitted to the Berlin Museum. W e should add that Sclater has examined the typical example of A. puna in that collection, and is convinced of its identity with the present bird. Mr. Whitely obtained two examples of this Duck on the lagoon of Tungasuca, which is situated in the Andes, south-east of Cusco, at an elevation of about 12,000 feet above the sea-level. The skins are both marked as " females ;" but the male, we suppose, would hardly differ, except perhaps in possessing rather brighter plumage. Mr. Whitely states that in the living bird the bill is light blue, with a streak of black down the centre of the upper mandible, the eye dark hazel, the legs and toes bluish slate-colour. He adds that he met with this Duck in pairs, but found it rather rare. Querquedula puna is a very well-marked species, and can hardly be confounded with any other member of the family. It seems to be most nearly allied to Q. versicolor, but is readily distinguishable by its larger and uniformly coloured bill, blacker head, whiter throat, and by the finer markings above and on the flanks. 9.
