188 FINE-BACKED SUN-BIRD. 



with blue on the wings and tail. On the band of 

 each wing there is a patch of rich violet-purple. 

 There are no axillary tufts. 



By the attention of Mr. Louis Frazer, we are 

 enabled to add a description of the female, from 

 specimens procured at Cape Coast and Accra, dur- 

 ing the progress of the late Niger expedition, and 

 forwarded to us for the use of the present volume. 

 Plumage above, including the wings, dark brownish 

 oil-green, deepest on the latter ; beneath, pale wax- 

 yellow, clearest on the centre of the belly; tail 

 nearly black, the outer feathers tipped with grey. 

 Length, three inches four-tenths ; of the bill to the 

 forehead, six-tenths. 



Mr. Swainson's specimens of his JV. erythronotus 

 were received from Senegal, and Yieillot's N. tri- 

 color, which we consider closely allied, if not iden- 

 tical, was from Malemba.
