the name of Buteo holospilus. These, from the apparent weakness of 

 their limbs, had hitherto generally been ranked among the Buzzards ; 

 although from the description of the courageous habits of the Bacha 

 Falcon, the only one well known of the group, doubts had been ex- 

 pressed of the propriety of ranking them with that tribe. Mr. Vigors 

 suggested the subfamily of Eagles as a more appropriate station for 

 them J where, united by many important characters to Pandion, they 

 apparently led off by the length of their tarsi to the genus Limnaetus 

 ('Memoirs of SirS. Raffles,' Append, p. 648.) and others of the long- 

 legged Eagles. The three species of the group were exhibited) their 

 general similarity in colour and markings pointed out ; and their spe- 

 cific differences explained. These consist chiefly in size, the Hcemat. 

 holospilus being one-third smaller than H. Bacha ; while H. undulatus 

 considerably exceeds the latter. The first is .spotted all over the body, 

 the second only on the abdomen ; while the third is marked by spots 

 on the wing-coverts, and by ocelli bearing an undulated appearance 

 on the abdomen, the breast also being crossed by undulating/oscitp.

A species belonging apparently to the family of Merulidce, and to 

 that portion of it which, from their long legs and short wings and tails, 

 indicate their station to be on the ground, afforded an opportunity ot' 

 characterizing a form which seems hitherto to have been unnoticed. 

 The length, strength, and arcuated culmen of the bill, and the length 

 and strength of the hallux, formed the most distinguishing points of 

 modification.
