[Eeceived February 18, 1884.] 

 (Plate XIII.) 



In a large collection of Birds from Shoa, sent to Italy by my 

 friend the late Marquis Orazio Antinori, I found four specimens of 

 a very fine Teal, with which I was not acquainted, so that I really 

 congratulated myself on the idea of describing a most beautiful new 

 species of the Duck-tribe. In this hope I was confirmed by the 

 fact that the species before me was not mentioned in the very 

 recent " List of the certainly known species of Anatidse," published 

 by Dr. Sclater in 1880 (P.Z. S. 1880, pp. 496-536). But I was 

 soon disappointed -when, having carefully looked into the subject, I 

 found that my bird was an old species, first mentioned and described 

 by Latham as " The Cape Wigeon," and afterwards named Anas 

 capensis by Gmelin. Although an old species, evidently it is not a 

 commonly known one, as in this case it would not have escaped Dr. 

 Sclater's well-known carefulness. I found also that its history and 

 even its proper name were involved in much confusion, that its 

 geographical distribution was much wider than was supposed, and 

 besides that the bird had never been figured, although Eyton tells 

 us that Smith was intending to give a figure of it in his ' Illustrations 

 of South African Zoology.' 



As said above, the first mention of the bird is in Latham's 

 'Synopsis,' where it is called "The Cape Wigeon." I do not
