324 Conspectus of the Ornithology of India, [No. 4. 



F. tinnuncularius, Vieillot. 



F. Naumannii, Fischer. 



F. gracilis. Lesson. 

 Hab. The warmer parts of Europe and Asia ; also N. Africa. 

 In India, found chiefly on the sub-Himalayas, Nilgiris, and other high 

 land ; though far from uncommon in Lower Bengal (perhaps in the 

 rainy season only).* 



25. T. vespertinus (PL EnL 431 ; Gould's B. E. pi. 27.) 



Syn. Falco vespertinus, L. 

 F. rufipes, Beseke. 

 F. subbuteo, var., Latham. 

 Hab. Europe, Asia, and N. Africa. In India, as the preceding 

 species, to which it is closely affined in all but colour. Both appear to 

 be wholly insectivorous. 



Genus Hierax, Vigors. 



26. H. melanoleucos, Blyth, J. A. S. XII, 179 (bis). 



Hab. Asam. 

 Remark. We have seen only one specimen of this strongly marked 

 species, which Mr. McClelland received alive from the province named. 



27- H. eutolmos, Hodgson. 



Syn. H. bengalensis apud Blyth, J. A. S. XII, 179 (bis). 

 Bengal Falcon, var. A, Latham. 

 Boung-oo-nhouk, Arakan. 

 Hab. Nepal, Sylhet, Arakan, Tenasserim provinces. 

 Remark. Edwards's figure of "the little black and orange Indian 

 Hawk," pi. 108, upon which are founded Falco ccerulescens, L., and 

 F. bengalensis, Brisson, has never been verified by the discovery of a 

 specimen, nor is a Hierax known to occur in Bengal ; but we never- 

 theless are of opinion that a peculiar and distinct species is represented 

 by the figure referred to, which may yet be recovered, and the more 

 probably as several species of this genus are now known, and we are 

 acquainted with but a single specimen of H. melanoleucos. 



* This and the next species we have never observed wild, but certain shik&ris take 

 many alive with bird-lime, and we have had several newly caught specimens (procur- 

 ed in the immediate vicinity of Calcutta) brought in the course of a few days. They 

 very soon become tame in captivity. The habits of both are doubtless as described 

 in Ann. Mag. N. H. 1843, pp. 413, 424.
