 What the bird from Gaboon mentioned by Dr. Hartlaub 

 (J. f. O. 1861, p. 169) may be, I am unable to say. 



Wahlberg describes his B. affinis as smaller than P. molitor. 

 I therefore add the measurements of some specimens for com- 

 parison : — 



As the females of B.pririt measure also 2*15 in the wing, 

 we may suppose that the two males above measured are really 

 of this species ; but I see no other point of distinction. 



I am not aware of any other instance in ornithology of two 

 birds being quite different as regards the females, the males
