ABSTRACT
THE eighth and ninth species of Crows are the Alpine Chough, and Cornish Chough. The first, Corvus Pyrrhocorax, is found in the Swiss Alps; and the second, Corvus Graculus, is perhaps the same as is called on the Sussex coast the Saddle-backed Crow. My authority for the name and description of this bird, Elements of Natural History,47 8vo., Cadell and Davies, describes it as being black and violet colour; but the colours of objects of natural history are, I have often observed, liable to be represented differently by different writers. Thus, in botany, flowers are often called scarlet, which I should call pink; and what is generally called purple is often by botanists called carnation, which ought to mean flesh colour.
