. Bulletin of the British Ornithologists' Club. Comparative Zoology for confirming the identification, and for obtaining the correct name of the lice from Robert Dalgleish to whom I am also indebted. An unreported hybrid Metopiana peposaca X Anas georgica by Milton W. Weller Received 3rd June, ip68 During recent studies of the plumages of certain South American ducks, a hybrid of the Rosy-billed Pochard, Metopiana peposaca (Vieillot) and Yellow- billed Pintail, Anas georgica spinicauda (Vieillot) was found at the Peabody Museum of Yale University. Since this previously unreported cross involves a genus of uncertain standing {Metopiana versus Netta of Delacour 1959), a description of the specimen seems worth recording. This specimen (Peabody Museum No. 22775) was collected by C. S. Reed at Batuco Lake in Santiago Province, Chile, in June 1938. It was recognised in the Yale collection because it had the general size and colour of a Rosy- billed Pochard, but had a black pattern on the bill like that of a Yellow-billed Pintail. The label has the following notes, showing that Reed recognised the bird as a hybrid, that it was collected with Yellow-billed Pintails and that he had compared it with 185 typical examples of that species: "Hibrido natural entre Metopiana peposaca (Vieill) y Peocilonetta spinicauda (Vieillot). Reed No. 5385 ; "Cazado en Batuco, en una laguna. Estaba una gran banadada de P. spinicauda (fue cazado con 185 ejemplares de P. spinicauda),y.
