imal side of the attacliment of the index digit, consists of an 

 elongated osseous hase, about 1*3 inch in length, slightly 

 recurved towards the radius. The horny covering, whichi is 

 shown in situ in the drawing [Sp), extends about "2 inch 

 further. The second spur [Sp. 1) is exserted nearly in the 

 same plane at the further extremity of the metacarpal ; 

 it is not quite so long, measuring, together with the horny 

 covering on it, about 1 inch in length, and is rather more 

 flattened in shape and has but slight indications of backward 

 curvature. Just in front of the first spur is situated the index 

 digit [D. 1) ; it consists of a long first phalanx measuring 

 about 1 inch in length, what is apparently a very short second 

 or ungual phalanx measuring only O'l inch, and a slight 

 pointed claw of about 0\2 inch in length attached to this 

 phalanx. Thus the whole first digit, from the base to the 

 extremity, measures 1*3 inch. 



Nothing can better illustrate the entire diversity, in origin 

 and position, of the " wing-spur " and " wing-claw " than 

 this specimen.

XX. — On some Papuan, Moluccan, and Sulu Birds. 

 By T. Salvadobi, C.M.Z.S. 



Through Dr. Nehrkorn's kindness I have been able to 

 examine some of the birds mentioned by him in his paper 

 " Zur Avifauna der Insel Waigiou" (Journ. f. Orn. 1885, 

 pp. 30-35), and I have found, as I suspected, that some 

 species have not been rightly identified. I should not have 

 mentioned this if it had had no bearing upon the geographical 

 distribution of some of the species ; but this being the case, I 

 think that it will be right to point out what those species 

 really are.

Out of twenty specimens attributed to the above-men- 

 tioned species, two have been presented by Dr. Nehrkorn to
