in no perceptible character from eight other specimens ; it is 

 possible that the females of P. insignis and 0. cablama may 

 resemble each other so nearly as not to be separable. Bu1 few 

 specimens have the sex indicated, but where it is, they are 

 marked as females, they differ in the lustre on their fronts, but 

 this may vary with age; the wings of the chestnut-bellied bird 

 are of the same length or a little shorter than those of P. hi 

 nis, and invariabl} 7 shorter than those of 0. cahlasma^ say from 

 4/ to f of an inch.

 for the present, not doubting that its true position will l»e 

 ascertained hereafter.
