APPENDIX O. 



On the Identity of Accipiter nisoides, Blytk, Accipiter gularis 

 {Temm. ^ Schleg.), and Accipiter stevensoui, Gum. ; also 

 on Accipiter virgatus {Temm.) and its two Subspecies, 

 Accipiter aflBnis_, Hodgson, and Accipiter manillensis, 

 Meyen. 



The following remarks would have been inserted in an earlier 

 portion of this volume^ but for the circumstance that it was 

 only very recently that I had the opportunity of examining 

 two adult males and an adult female (all obtained in Japan) 

 of the Hawk for which, in the abis' for 1863, p. 447, I 

 proposed the specific name of " stevensonij" 



One of these specimens, procured at Tate-yama, was very 

 kindly lent to me by Mr. Blakiston, and the other two form 

 part of a valuable collection of Japanese Raptores lately pre- 

 sented to the Norwich Museum by Mr. Ringer, who obtained 

 them at or near Nagasaki. 



The fact, with which I thus became acquainted, of the 

 occurrence in Japan of Accipiter stevensoni has suggested to 

 my mind that the description and plate of "Astur (Nisus) 

 gularis'' in the ' Fauna Japonica^ represents my Accipiter 

 stevensoni, and not, as I had previously supposed, the large 

 northern form of Accipiter virgatus. 



The examination of the adult specimens from Japan to 

 which I have just referred, and of several immature Japanese 

 examples in the Norwich Museum and in the collection 

 of Mr. Blakiston, has confirmed my present belief that 

 A. stevensoni is not separable from the true A. gularis.
