WHITE-EYEBROWED LONGTAIL. 41 



have yet received from Senegal, figured in any 

 -work, we must consider it as new; it is very in- 

 teresting to the ornithologist, from being an aberrant 

 species, that is, forming a passage from its own 

 genus to that of Prinea. This is apparent from 

 the inner toe being rather the shortest, while the 

 anterior tarsal scales, always distinct in the other 

 species, are in this scarcely perceptible. 



The general plumage above is of a light drab 

 brown, without any spots, but having a white 

 line above the eyebrows. The under plumage is 

 also unspotted and white, the thighs and flanks 

 being strongly tinged with ferruginous. The tail is 

 of the same brown as the back, but the ends of the 

 lateral feathers are blackish, with their tips dull 

 white. The bill is deep black, the legs pale, and 

 the outside of the wings tinged with ferruginous; 

 the fourth and fifth quills are longest, and the rictus 

 is slightly bristled. 



Total length, 4 inches ; bill, T 4 5 ; from the front
