Mr. R. B. Sharpe’s Catalogue of Accipitres. 215 
in this series is 1°9 inches, in one specimen; the length is 2 
in twelve, 2:1 in five, and 2°2 in one. The middle toe s. wu. 
measured 1:9 inches in three specimens, 2 in seven, 2°] in 
five, and 2°2 in four. 
The largest male in the above series (ascertained to be so 
by careful dissection) has a wing-measurement of 16°55, tarsus 
2-1, and middle toe s. uw. 2:0. ‘ 
With regard to the dimensions of Indian females of this 
species, Mr. Hume writes thus in ‘Stray Feathers,’ vol. i11. 
p- 36:—“ The females vary in length from 26 to 28; the 
smallest wing of any female I have met with was 15°75 ; and 
I have one before me, now, with the wing full 18.” 
Mr. Holdsworth, in the P. Z. 8. for 1872, p. 415, and Cap- 
tain Legge, at p. 91 of his ‘ Birds of Ceylon,’ mention an 
opinion which I formerly entertained, that specimens of P. 
ptilorhynchus ‘‘from Ceylon are usually larger than those from 
India;” but I have subsequently ascertained that this opinion 
was ill founded, there being little, if any, difference between 
the average size of specimens obtained in India and Ceylon. 
For detailed measurements of Ceylon specimens I would refer 
to the account of this species in Captain Legge’s work. 
I have noted the following measurements, taken by myself 
from specimens collected in various continental localities to 
the east of the Bay of Bengal.

Mr. Hume, in ‘Stray Feathers,’ vol. iii. pp. 86, 37, gives 
the measurements of three small females from Thayetmyo, 
and adds, “Taking the dimensions of these three females,
