154. (?) Astur soloensis ( Horsf. ), 



/"aZco soZoensts, Horsfield, Trans. Linn. Soc.xiii, 1821, p. 137 (Java). 



Astw- soloensis, A., p. 8 (Malewoon and Mergui) ; F., p. 22 (Lang- 

 kawi Ids.). 



Apparently not common, very likely often confused with 

 Accipiter gularis. 



Sharpe ( Cat. Birds Brit. Mus. ) and Swann* ( Synopt. List 

 Accipitr. i, p. 25, 1920) are. inclined to keep separate A. soloensis 

 and A. euculoides (Temm., PI. Col. 1823, pi. 129). For the present, 

 however, we are disposed to regard the latter, with its uniform 

 tail, merely as the very adult bird. Both were originally described 

 from Java, A. soloensis from Central, and A. euculoides from 

 Western, Java. 



155. Accipiter gularis (Temm. & Schleg.). 



Astw gularis, Temm. &, Schleg., Faun. Jap. Aves, 1845-50, p. 5, 



pi. 2. 

 Accipiter gularis, Ogilvie Grant, Ibis, 1896, p. 104; Hartert, Nov. 



Zool., xvii, 1910, p. 211.

The wings of these are : —ad. 172-168 ; imm. 159 mm. 



The possession of specimens of the typical A. virgatus from 

 Java, and others agreeing with it from Sumatra, enables us to state 

 with some degree of confidence that the typical form of that species 

 is not likely to occur on the continent of Asia, \iA.v. hesra, from 

 Southern India and Cejdon, is maintained as distinct. Adult females 

 of A. virgatus and A. gularis are totally distinct, but the males ( if 

 it is true that the form described as A. rufotihialis from Kina Balu, 

 N. Borneo, is merely the adult of A. virgatus) approximate, except 

 in size, the insular bird being much the smallest. It is, therefore 



*This author has, however, sunk A. euculoides as a synonym in the 

 2nd edition of the above quoted work (Part i, 1921, p. 41).
