 edged with white towards the tip ; middle tail-feathers deep 

 glossy-black with a very narrow yellow edging at the tip, the 

 other feathers black at the base, the outer ones for the most part 

 yellow and the inner ones for the most part black, those nearest

The absence of the white alar speculum seems to be the dis- 

 tinguishing character of the pi-esent species. I have examined 

 the type-specimens which are in the British Museum, and sub- 

 join their measurements along with those of two other specimens 

 now lying before me.

Dr. Finsch considers this species to be identical with 0. 

 haruffii, from which, however, it differs perceptibly in having no 

 white alar speculum, and also in having the tail-feathers blackish, 

 faint olive-yellow only near the base. The presence of this 

 colour may indicate that in time the whole of the rectrices will 

 become olive-yellow. If this is proved to be the case ultimately, 

 Dr. EinscVs supposition may be right ; and in that case O. nigri- 

 pennis will be the young, 0. baruffii the intermediate stage, and 

 O. hrachyrhynchus the old of one and the same species. 1 confess 

 that I should not be surprised at this; and another fact may be 

 mentioned in favour of their identity, namely that they all three 

 inhabit the same localities, specimens of each having been ob- 

 tained at all the collecting-points from Sierra Leone southwards 

 to Gaboon.
