GREAT-BILLED CROW . — Corvus crassirostris. 
The remarkable bird which has very appropriately been called the Great- 
Billed Crow, is the most singular example of the whole tribe. 
In its dimensions it is much larger than an ordinary crow, and rather smaller 
than a raven, for which bird it might be taken, but for the extraordinary beak. 
The bill of this species is so large as to remind the observer of a toucan or a 
puffin, and the bite of such a powerful weapon must be most formidable. It is 
very deep, thick and rounded, becoming wider at the top and deeply ridged, 
curving suddenly to a point, and very sharp at its extremity.
