12 Mr. D. A. Banncrman : A Revision 



the male of H. poensis becomes synonymous with that 

 species, the latter name having priority. 



A bird obtained by Alexander on the 20th of November, 



1902, and now in the British Museum, is labelled " ? ," but 

 I have no doubt that the sex in this case has been wrongly 

 determined. It appears to be an immature male, and the 

 brown feathers, which have not the slightest tinge of rufous 

 as in the female, are just commencing on the breast and 

 belly to become grey. It has the greenish gloss on the 

 mantle characteristic of the male, whereas the female has a 

 more pinkish gloss on the mantle. 



In Alexander's paper on the Birds of Fernando Po (' Ibis,' 



1903, p. 396) he includes his Haplopelia poensis as a synonym 

 of H. simplex, having come to the conclusion that the brown 

 female which he shot in Fernando Po and made the type of 

 H. poensis is in reality the young of H. s. simplex. It is 

 almost impossible to distinguish the young male of H. s. 

 poensis from the hen of H. s. simplex. The bird which 

 Alexander shot in Fernando Po on the 20th of November, 

 1902, and determined the sex to be a female, is almost 

 certainly an immature male as I have already pointed out. 

 Count Salvadori quite correctly recognized H. poensis as a dis- 

 tinct species in his valuable paper on the Birds of Fernando 

 Po (Mem. Accad. Sci. Torino, 1903, p. 121), and gives his 

 reasons, which are very sound, for refusing to unite H. s. 

 poensis with H. s. simplex in ' The Ibis/ 1904, p. 369. 



Count Salvadori was perfectly right in keeping as distinct 

 races H. s. simplex, H. s. poensis, and H. principalis., so 

 that I have no doubt the new form which he has described 

 from Annobon will prove to be valid.
