106 Mr. D. A. Bannerman on rare Birds [Ibis, 
seems to be the first record of this species from Came¬ 
roon . 
We have specimens in the British Museum from the 
Egyptian Sudan and Abyssinia in the east, and from 
Sierra Leone, Gold Coast, French Congo, and Portuguese 
Congo in the west. 
Spizaetus africanus. 
Limnaetus africanus Cassin, Proc. Acad. Philad. 1865, 
p. 4—Type locality: Ogobai River, Gaboon. 
The only specimen which Mr. Bates procured of this rare 
bird—a male shot on the 16th of December, 1913, at Bitye, 
R. Ja—was described by Mr. W. L. Sclater (Bull. B. O. C. 
xxxix. p. 87) as Spizaetus batesi, sp. nov. Mr. Sclater had 
then overlooked the fact that what must evidently be the 
same bird had been already described by Cassin ; but he 
discovered and corrected his mistake himself in the following 
number of the f Bulletin 9 (vol. xxxix. pp. 93, 94). 
Pteronetta hartlauhi. 
Querquedula hartlaubi Cassin, Proc. Acad. Philad. 1859, 
p. 175—Type locality: Camma and Ogobai (Gaboon). 
Pteronetta hartlaubi Sharpe, Ibis, 1904, p. 98, 1907, 
p. 425; Bates, Ibis, 1909, p. 6, 1911, p. 482. 
Pteronetta hartlaubi albifrons Neumann, Bull. B. O. C. xxi. 
1908, p. 42. 
In 1908 Oscar Neumann gave a name to the form of 
Hartlaub’s Duck from the Upper Congo, Ituri, and Uele 
Rivers, naming it P. h. albifrons. He separated it from 
typical examples of P. hartlaubi (Cassin) on account of 
adults of both sexes having “ a large white patch on the 
forehead, extending to the middle of the vertex/’ noting 
“in the West-African form the females never had any white 
on the head, but in the males there were sometimes a few 
white feathers on the forehead/'’ 
In ‘The Ibis,’ 1911, p. 482,Mr. Bates makes the following 
interesting observation:—“ Male specimens (Nos. 3661 and 
4143) from Cameroon have a small white spot on the fore-
