Whilst two specimens shot at Laehung had the following dimensions : —

2, 1325 8-75 2-4 2-35 20- 



Neither of these had completed its motdt, but probably the longest 

 quills and tail feathers are full grown. A specimen obtained by Dr. 

 Stoliczka in Western Tibet measures

And in all the bill, although not longer from the gape, is stouter and higher, 

 and the gonys apppears longer. But on the other hand a specimen brought 

 by Captain Elwes from Laehung has the wing only 12 "2, tail 8 inches, 

 whilst a specimen from the Chola range has the same measurement precisely. 

 The sexes are unfortunately not recorded on my specimens. 



Under all the circumstances I do not like to propose a new name, but it 

 is quite possible that the Himalayan form is larger than that found in the 

 plains of India. The dimensions given by Jerdon for G. culminatus : 

 length 21 inch, wing 13f, tail 7-|, equal those of Himalayan specimens. 

 This variability in size probably explains the difference of opinion between 

 Mr. Blyth, (Ibis, 1868, p. 132,) and Captain Beavan with Colonel Tytler 

 (Ibis, 1867, p. 328), as to the distinction, or otherwise, of the Andaman crow. 

 Specimens of G. Vaillaiiti from Malacca precisely resemble those from 

 Bengal. 



Crows were common up to about 13,000 feet, above which elevation 

 they seemed to be replaced by ravens. They appeared far more abundant 

 about 8,000 feet in the higher valleys than below that elevation ; there were 

 large flocks of them near most of the villages, but, as usual with G Vaillaiiti, 

 not about houses like the Indian G. splendens. 



666 Nucifbaga hehispila, Vigors. — This is rare on the outer ranges 

 of Sikkim, but common in the pine forests of the interior. It is not a very 

 wary bird, but is usually to be seen on the edges of open glades or on trees 

 outside the forest. Its cry and flight are both decidedly corvine. I once saw a 

 pah' hawking after butterflies just as crows may sometimes be observed to do ; 

 the white of the outer tail feathers becomes very conspicuous when the birds 

 are thus engaged. The iris is dark brown.
