of the Genus Haplopelia. 15 



examined, it will be seen that H. s.jacksoni has the under- 

 parts suffused with a pinkish wash, while in H. s. simplex 

 the uuderparts are grey, only faintly washed in some cases 

 with pinkish. The best distinction is undoubtedly to be 

 found in the bill, which is much shorter in H. s. jacksoni 

 than in the typical form. The bill in the adult specimens 

 of ^. s.jacksoni measures 13 mm., while in H. s. simjylex it 

 varies from 15-16 mm. in adult male birds. 



Mr. Ogilvie-Grant has already published a description 

 of the female and young of this species and of a bird in 

 intermediate plumage which were procured by the Ruwenzori 

 collectors, from which I quote the following : — " The adult 

 female has the upperparts earth-brown, shading into bronzy- 

 rufous on the upper mantle, nape, and occiput, and there is 

 no trace of the grey, violet- or green-glossed mantle which 

 characterises the male; the entire underparts below the neck 

 as well as the under tail-coverts are rich vinous. ^^ 



The immature male has the upperparts similar to the 

 adult male, save that the wings are glossed with pinkish- 

 purple instead of with golden-olive, while the underparts 

 are rich vinous like the adult female. 



Haplopelia forbesi. 



Haplopelia forbesi Salvadori, Ibis, 1904, p. 368. 



Range and Type-locality. Unknown. 



Count Salvadori has already given a long history of this 

 Pigeon in ' The Ibis,-" where he includes a detailed latin 

 description of the bird, which he names H. forbesi. 



This Pigeon appears to have been first mentioned in the 

 ' Catalogue of the Pigeons in the Derby Museum," where it 

 was referred to as H. principalis Hartl., and said to have 

 been obtained in Cayenne ! Count Salvadori, having 

 examined the bird, pronounced it to be an undescribed 

 species, probably from West Africa. 



The bird, which is almost certainly a female, although the 

 sex was not ascertained by the collector, is remarkable in 

 having the under tail-coverts white, thereby differing from 

 the hens of the other known species of Haplopelia. 



The type is in the Liverpool Museum.
