LIST OF DTTJRNAL BIRDS OF PREY. 



I have examined four adults of this subspecies, from which 

 I have taken the followiii": measurements : — 



Specimen No. 3 in the above list was sent to the late Lord 

 Tweeddale, together with two very young birds, probably 

 of this species, and a typical adult female of A. nisoides 

 [= stevensoni), all four having been obtained by Mr. Everett 

 within ten miles of Zamboanga, in the Island of Mindanao, in 

 April 1878 : the four skins were kindly lent to me by Lord 

 Tweeddale, and I expressed an opinion, which I now tind to 

 have been erroneous, that they were all referable to "Accipiter 

 stevensoni" thinking that the bird which I now consider is an 

 adult of manillensis was probably a somewhat abnormal female 

 of the species which I had called A. stevensoni, though I was 

 so far doubtful of such being the case that I wrote to Lord 

 Tweeddale that "if it should ultimately prove distinct it 

 would by no means surprise me.''^ 



Lord Tweeddale described the four skins in the '^Pro- 

 ceedings of the Zoological Society," 1878, p. 938, also figuring 

 very accurately, at pi. 57 of that volume, the specimen now 

 under consideration ; and, acting on my mistaken suggestion, 

 he applied to all four the name of " Accipiter stevensoni."
