70 RIKDS OF INDIA. 



Gen. LiMNAETCS, Vigors. 



Si/n.—Spizaetus in part, AucU—Nisaetus, HoDGSON (in part)— 

 Lojihaetus, Kaup. 



Char. — Bill short, high at the base, curved, hooked at the tip, 

 with a prominent festoon in the upper mandible; wing short; 

 tail lou"-', square ; tarsi long, moderately strong, feathered to the 

 base ; toes unequal, large ; claws large, strong and much curved ; 

 head usually crested. 



This genus differs from the last in the shorter and more Hawk- 

 like bill, in the shorter wings, and in the head being usually 

 crested. It is placed by Bonaparte and Horsfleld among the 

 Accijntrince. Gray, in his last published list of genera, refers the 

 species to Limnaelus, retaining Spizaetus for the American 

 birds. 



There are several Indian and Malayan species, whose claims to 

 specific distinction, and synonymy, are not yet accurately defined. 

 I give four Indian species.
