J88 CYMINDIN-flE. 



Mr Vigors to this bird and to the N. Riocourii, 

 \\hen he mide out his valuable observations on 

 the " affinities of birds." They appear to us to 

 differ considerably, and we are now inclined to 

 adopt for the long and fork-tailed species the 

 generic title of the latter ornithologist. 



NAUCLERUS. Generic character. Bill short, 

 weak, compressed ; nostrils oval, oblique, 

 covered with bristles at the base ; wings 

 long, the second or third quill longest ; tail 

 Jong, very much forked ; feet short, weak, 

 tarsi reticulated, the acrostarsia below the 

 knees plumed to the middle, claws nearly 

 round ; body slender. (Vigor's Zool. Jour.)
