ORDER PASSERES. 411 



Cinclus Mexicanus, Swain. 

 Cinereous ; gray head ; and chin brown. Mexico. 



Perhaps the genus Colluricincla of Vigors and Hors- 

 field should be added in this family. 



Colluricincla Cinerea, Lin. Trans. 13. 

 Ashy above, paler underneath, with the throat and 

 before the eyes white ; under the wings brown. Found 

 in New Holland. 



And also the genus Sphecothera of Vieillot, which 

 has the bill thick, straight, and bald at the base, and 

 curved at the top ; the orbits naked ; and the first and 

 third quill the longest. 



Sphecothera Viridis, Vieil. Gal. t. 148. 

 Greenish ; beneath yellowish ; head, bill, and feet 

 black. New Holland. 



Africa, and the countries which border on the Eastern 

 Ocean^ produce a genus of birds approximating to the 

 Merles, which I shall name 



Philedon. 



Their beak is compressed, slightly arched in its entire 

 length, and sloped at the end. Their - nostrils are 

 wide, with a cartilaginous covering, and the tongue 

 terminated by a brush of hairs. 



The species for the most part remarkable for some 

 singularity of conformation have been thrown into all 

 kinds of genera by authors. 



Some have prominences on the beak, others have 

 fleshy appendages at its base.
