 Dr. Reichenow gives 130 mm. as the wiug-measureraent of 

 the specimens which have come under his notice. 



Section B. 



Such confusion has occurred with respect to the members 

 of this section of the genus that, before dealing with the 

 individual species and subspecies, I wish to give a short 

 risume of the chaos into which the birds from Cameroon, 

 the islands in the Gulf of Guinea, and Uganda have fallen. 



First of all, Hai-tlaub, in 1849, described from St. Thomas 

 Island a Pigeon, which he named Haplopelia isimpled; which 

 therefore becomes the type of this group. 



In 1866 Hartlaub described the bird from Prince's Island, 

 which he named H. principalis. 



Next, H. inornata was described by Dr. Keichenow from 

 Buea, Cameroon Mt., in 1892, and from the description the 

 type is apparently a female, brown in colour. 



In 1903, Boyd Alexander discovered and described a bird 

 from Fernando Po, also a female, with the under surface of 

 the body rufous earth-brown, which he named H.poensis. 

 Also in 1903 Count Salvador! described H. hypuleuca, a grey- 

 breasted bird from Annobou. 



In 1904, Dr. Sharpe obtained a young bird still retaining 

 the rufous tips to the featliers of the mantle and wing- 

 coverts from Efulen, Cameroon, which had been shot by 

 Mr. G. L. Bates. This bird was beginning to assume a grey 

 breast, and Sharpe compared it with H. principalis ; finding 

 it showed marked differences from the Prince's Island bird, 

 he described it as new, notwithstanding its being a very 

 young bird, and named it H. plumbescens. 



In the same year (1904) an adult male grey-breasted 

 Pigeon was obtained by Seimund in Fernando Po. Sharpe 

 also described this bird and named it H. seimundi, consider- 

 ing it perfectly distinct from the brown bird which Alexander 

 had obtained in this island, and had already named H. 

 poensis.
