quote his description, for it refers very obviously to a young 
male Visus, pur et simple. It appears to be the dimensions which 
misled him these he gives, as wing, 8. Tail, 5°75. ‘Tarsus, 
2°13. Mid toe, 1°63; and he adds that these dimensions are evi- 
dently intermediate between those of Visuws and Nisoides. This 
however is a mistake. The wings of a number of male Wisus, 
European specimens, varied from 8-13 to 8°38. An Indian 
specimen has the wing, 7°6, and he himself sent home a speci- 
men (according to Von. Pelzeln. Ibis, 1868) with the wing 
7°25. The tailsof the European birds varied from 6°55 to 
6°88, that of the Indian bird is 6°4; the tarsus of this latter 1s 
2°2, and its mid toe to root of claw, 1°45; so that his dimen- 
sions, though small, are not sufficiently so to induce doubts of 
the specimen being a WVisus, while the plumage he has so ac- 
curately described, is unmistakably that of a young, but not very 
young, bird of that species. Von Pelzeln came to the same 
conclusion ; ; he says ‘‘ One individual, evidently a male, is ticket- 
ed Accipiter Nisoides, Blyth (A. Gularis, Schlegel;) but in my 
opinion all the examples belong to the true A. Wisus.” 
In the same paper in the Asiatic Society’s Journal, in which 
he described the young JVisus, he added the following valuable 
remarks about the type specimens of A. Nisoides. 
“On comparing Mr. Blyth’s originals in the Indian Museum, 
I found that one of the three originals is lost, the other two 
very much resemble in the upper dark brown colouring our 
specimen, and one of them has some of the tips of the scapulars 
and tertiaries distinctly tipped with rufous brown. ‘The cross 
bars below are, however, ochreous yellow, only with a slight fer- 
ruginous tint on the sides of the breast, but not nearly to the 
extent described in our specimen. ‘This cannot be, however, 
of very great 1mportance, for the same colour is very variable in 
A. Nisus. The throat is white, and so far as the feathers are pre- 
served, they present a fow dark streaks about the middie, though 
on this point neither of the specimens is quite perfect, and it is 
only to be regretted that such valuable originals were not bet- 
ter cared for. The measurements given by. Mr, Blyth are, wing 
7% imches; tail 53 inches. The two respective specimens in the 
Indian Museum have the wings 7$ and 7?; and the tail 5 
and 52 inches. Mr. Blyth supposed the specimens to : 
females, but they could with as much reason be regarded 
males. Still it cannot be questioned that the typical specimens 
referred to, are remarkably small as compared with usual speci- 
mens of A. Nisus. I found this difference especially apparent 
after having a short time previously procured in the lower hills 
several speciinens of the last species. The claws appear remark-
