obtained by Christy on the Bomakandi, in the Uelle 

 district of north-eastern Belgian Congo. On the other 

 hand, Alexander collected a bird obviously of the typical 

 race also in the same district. Until more material is 

 obtained it would be advisable to keep the two forms as 

 distinct species. 



Pteronetta hartlaubi. 



The Duck described by Neumann as Pteronetta hartlaubi 

 alhifrons (Bull. Brit. Orn. CI. xxi. p. 42, 1908 : Ituri forest) 

 is undoubtedly identical with P. hartlaubi, and the white 

 frontal patch appears to be a character distinguishing the 

 males from the females, as is shown by a good series of 

 three males and four females from Cameroon collected 

 and carefully sexed by Mr. Bates. Some of the other 

 examples in the Museum seem to be wrongly sexed (see 

 Bannerman, ' Ibis,' 1921, p. 106). 



ViNAGO WAALIA. 



The original reference for this species given in the 

 'Catalogue' (vol. xxi. p. 15), and generally quoted, is to 

 the Grerman translation of Bruce's ' Travels in Abyssinia,' 

 published in 1791, and edited with notes by Gmelin. On 

 turning up the reference it will be found that, though 

 diagnosed, no definite Latin name is given to the Green 

 Pigeon by Gmelin. The earliest description with a definite 

 name appears to be by F. A. A. Meyer (Sj'-st. Sum. Uebers. 

 Zool. Entdeck. p. 128, 1793), who names it Columba 

 waalia. 



TURTUR AFER. 



Of this species, which has a wide distribution from Senegal 

 and Abyssinia to the Zambesi valley, I can only distinguish, 

 apart from T. a. mearnsi recently described, two racial 

 forms, a paler and a more richly coloured one, as follows : — 



T. a. afer (Linn.), founded on Brisson's description of 

 a bird from Senegal ranging south to the Gambia and 

 Portuguese Guinea, where it merges into the darker form,
