10 Mr. E. Blyth on the Birds of India. 



25. T. SATURATUS, Blyth, J. A. S. xxviii. p. 277. 



Syn. ? T. moluccensis, Schlegel, vide P. Z. S. 1860, p. 343. 

 Hah. Indo-Chinese region. (The adult male remains to be 

 described * ; while T. alaudarius is likewise found in Burma.) 



Genus (or subgenus) Erythropus, Brehm. 



26. E. cENCHRis. (Gould, B. E. pi. 29.) 



Syn. Falco cenchris, Naumann. F. tinnunculoides, Schinz. F. 

 tinnuncularius, Vieillot. F. xanthonyx, Natterer. F. naumanni, 

 Fleisch. 



Hab. "Abundant in many districts of the Lower Himalayas, 

 and preys much on the Mountain Pipit^' (A. L. Adams) ; Nil- 

 giris : visits Lower Bengal during the rainy season. 



27. E. vESPERTiNus. (Gould, B. E. pi. 23.) 

 Syn. Falco vespertinus, L. F. 7'ujipes, Bechstein. 



Hab. Europe, Asia, N. Africa : more diffused over India than 

 the preceding species, and (like it) visits Lower Bengal during 

 the rainy season. " The most common Hawk in Asia Minor " 

 (Fellowes, in Ann. and Mag. Nat. Hist., Nov. 1839, p. 213). 



Genus Hierax, Vigors. 



28. H. MELANOLEUcos, Blyth, J. A. S. xii. p. 176 bis. 



Hab. The only specimen that I have seen was brought alive 

 in a cage from Assam. Another is noted dubiously in Horsfield^s 

 Catalogue, from that comprehensive region " India^^f- 



* Since received. It differs less from the adult male of T. alaudarius 

 than the females and young of the two races differ, but is still very deep 

 coloured. 



t Edwards's figure of " the Little Black and Orange Indian Hawk," 

 pi. 108 (an example of which was brought in spirit "from Bengal in the 

 East Indies "), upon which figure are founded Falco ccerulescens, L., and 

 F. bengalensis, Brisson, appears not to have been verified by the discovery 

 of a second specimen, nor is a Hierax known to inhabit Bengal ; but I 

 am nevertheless of opinion that a peculiar and distinct species is represented 

 by that figure, which may yet be recovered, and the more probably as six 

 species of this genus are now recognized, and of these only a single speci- 

 men (for certain) is known of H. mclanoleucos. In P. Z. S. 1860, p. 343, 

 " H. ccerulescens" is noted as an inhabitant of the Moluccas— H. fringil- 

 larius being probably intended.
