BIRDS OF ETHIOPIA AND KENYA COLONY 39 



This species is more than subspecifically distinct from the North 

 American green-winged teal and the two should be kept as species, 

 not as races as Hartert has done in the " Vogel der Paliiarktischen 

 J'aima." 



On March 18, at Lake Abaya, 12 of these ducks were seen by 

 Doctor Mearns. 



DENDROCYGNA VIDUATA (Linnaeus) 



Anas viduata Linnaeus, Syst. Nat, ed. 12, voL 1, p. 205, 1766: Cartagena, 

 Clolombiu. 



Specimens collected: 



Adult female, Lake Kudolf, Kenya Colony, July 5, 1912. 



The specimen listed above has the black throat band interrupted 

 by white in the midventral line, agreeing in this respect with two 

 birds from the White Nile (Fashoda and Lake No) and differing 

 from a pair from Kilosa, Tanganyika Territory, and from one from 

 Ethiopia, in the Museum of Comparative Zoology. The complete- 

 ness of the black band may be a character of age. The crown is 

 much stained with tawny, the cheeks slightly so. 



A large number of specimens of both sexes from various localities 

 in Africa and South America presents no variations other than in- 

 dividual or due to wear. The present example is rather large (but 

 not unusually so) having a wing of 230 millimeters; tail of 62 milli- 

 meters; and culmen of 46.5 millimeters. The largest of a series of 

 seven males from the Sudan (Lake No, White Nile) has the follow- 

 ing measurements : Wing, 231 millimeters; tail, 58 millimeters; cul- 

 men, 48 millimeters (measurements in both cases by E. A. Mearns). 



This species was not recorded from Turkanaland by Doctor van 

 Someren, in his paper on the birds collected by Captain Gemmel ®^ 

 and, as far as I know, this specimen constitutes the first record for 

 that little-known region (using Turkanaland in a very broad sense, 

 including the Rendile country). 



On Lake Rudolf about a thousand of these ducks were seen on 

 July 5-8, and a few others were noted several days later. 



ALOPOCHEN AEGYPTIACUS (Linnaeus) 



Anas aegyptiacus Linnaeus, Syst. Nat., ed. 12, vol. 1, p. 197, 1766: Egypt. 

 Specimens collected:

 Adult female, near Saleish, Ethiopia, January 17, 1912. 

 Adult male. Tana River at mouth of Thika River, Kenya Colony, 

 August 24, 1912.
