220 ORIOLID^. 



Since I previously discussed the question of the identity of 0. 

 haniffi with 0. hmcJiyrhynchus (' Ibis,' 1870, pp. 226-228), the 

 material at my disposition has been greatly increased, and I now 

 believe them to constitute only one species. The chief difference 

 pointed out by me (I. c.) was in the marking of the four tail- 

 feathers, 0. haruffi. having the feather on each side next to the middle 

 one marked with black. This, however, seems to vary with age, 

 being present in the young birds and gradually disappearing with age, 

 the yellow tips, however, increasing in extent as the bird gets older. 



The present species in its adult stage is very closely allied to the 

 small form of 0. larvatus, called by Salvadori 0. rolleti ; but, inde- 

 pendently of its smaller size and the totally different aspect of the 

 young bird, the West- African species may be recognized by its much 

 smaller alar speculum and by its olive-yellow secondaries, coloured 

 like the back, with only a little of the inner web blackish ; the 

 secondaries in 0. larvutus or 0. rolleti are black externally, edged 

 with olive-yellow or greenish.
