and bold, and it was impossible to leave anything eatable 
about which it did not attempt to steal. Even milk-pots it 
would deliberately upset to obtain a sup of the contents. 
At the greatest altitudes and through the most absolute 
deserts at least half-a-dozen accompanied the camp, some 
doubtless of the very same birds thus travelling the whole 
way from Le to the vicinity of the city of Yarkand ; when the 
camp divided about half the ravens went with each party. 
On first starting in the morning they always accompanied 
the party to a short distance, and then they returned to the 
old camping ground, apparently to make sure that nothing 
eatable had been left behind, and there they might be seen 
prowling about wisely for an hour or so, again joining the 
party in the afternoon at the new camp. [G. //.] 
This species is a larger bird and has a very much stronger 
and more massive bill than the so-called C. corax, so 
common throughout the plains of the Panjab, but it appears 
to me very questionable whether this latter bird does not 
require specific separation from the English one. I have 
unfortunately no English specimens with which to compare, 
but a Greenland specimen labelled C. littoralis, though sent 
from Europe as C. corax, is a much larger bird than either 
the Panjab or the Tibet Raven, and has a very much more 
powerful bill and feet than either of the latter. In the 
Greenland specimen the bill measures 3'''4 at front, straight 
from forehead to point ; while similarly measured, the bills 
of the Panjab birds do not exceed 2'" "8, and those of the 
Tibetan birds 3''-18. The height of the two mandibles closed 
is about I'^'O in the Panjab birds, V'-% in the Tibetan birds, 
and V'-'Z^ in the Greenland specimen. No male of the 
Panjab bird out of numbers measured in the flesh exceeded 
24'^- 75 inches in length, no female exceeded 23'' "75, and no 
male weighed more than two pounds five ounces. If the 
Panjab bird be considered worthy of specific separation it 
might appropriately bear the designation of Corvus Laurencei, 
in memory of a late viceroy, so long and intimately con- 
nected with the Panjab. 
I note that Dr. Jerdon's dimensions of the Indian Raven 
must have been taken from European authors and not
