Raptorial Birds of the Malinj Archipelago. 2 1 f) 



The Quail, Coturnix communis, is the only other Gallinaceous 

 bird that came under our notice. A few pairs might be found 

 here and there throughout the winter ; but in March they re- 

 turned from the south by myriads in a single night, and remained 

 in all the open plains, marshes, and cornfields.

XVIII. — Corrections of, and additions to, the Catalogue of the 

 Raptorial Birds of the Malay Archipelago'^. By Alfred R. 

 Wallace, F.Z.S. &c. 



I AM indebted to Mr. J. H. Gurney for calling my attention 

 to an important omission and error in the above-mentioned list. 

 I have placed under Spisaetus cirrhatus, as a synonym, Nisaetus 

 ulhoniger, Elyth, quite overlooking the plate iu Part 15 of Mr. 

 Gould's ' Birds of Asia,' from specimens in the Norwich Museum 

 which show it to be a distinct species. 1 also describe and figure 

 as new Spizaetus nanus, which may probably be the young of 

 S. alboniger, although it presents several curious differences. 

 Mr. Gurney kindly sent for the two specimens from Norwich to 

 compare with my bird. The brown individual (figured by Mr. 

 Gould on the same plate) is undoubtedly the same as mine ; but 

 they both differ from >S^. alboniger in the smaller feet (the inner, 

 middle, and hind toes and claws being especially shorter and 

 slenderer), and in the larger amount of feathering of the middle 

 toe. We then proceeded to the British Museum and found two 

 specimens said to be from Borneo : — one closely agreeing with 

 S. alboniger ; the other corresponding in the foot-characters with 

 my S. nanus, but approximating somewhat in size and plumage 

 to S. alboniger. This latter bird is the one named S. borneonen- 

 sis in Mr. G. R. Gray's List of Accipitres, but not described. 

 I cannot, therefore, decide whether the three smaller and brown- 

 plumaged specimens [S. nanus) are identical with the two larger 

 black-and-white birds, which are decidedly S. alboniger; and 

 Mr. Gurney agrees with me that the case is still a doubtful 

 one. 



The following corrections require to be made to my catalogue.
