been obferved to me +, that a female raven weighs two pounds ten 
ounces, but the egg fearcely feven drams, fo that forty-eight of them 
would only make up the weight of the bird. The egg of the Cuckow 
is lefs difproportionate, requiring only thirty-eight to equal the parent 
in weight. 
Levaillant found that ef which he gives a figure, in Saldanha Bay, at 
the Cape of Good Hope, where it not unfrequently unites in large flocks, 
attacking young antelopes, and likewife killing them: that the 
male and female are generally tegether, making the neft in the clefts 
of rocks, as well as in old buildings. This is certainly a variety only 
of our Raven, differing roerely in being bigger, and the bill a trifle more 
bent.

R. Levaillant is certain that it is a diftin@ fpecies; he obferves, 
that it is rather lefs than a Raven, and is eighteen inches in 
length, with a cuneiform tail, and the wings are three inches longer : 
it is flrongly characterifed by a white patch at the nape of the neck, 
added to a white mark feparating the fides of this white patch, and 
encircling the neck; this ftripe is itfelf not very apparent, being
