Although I have placed all the species known by the trivial name of Coquettes in the genus Lophornis, the L. chalybeus and L. Verreauxi have been separated by M. Cabanis into a distinct genus, under the name of Polemistria.
These birds, as will be seen on reference to the plates on which they are represented, vary considerably from all the true Lophornithes; the feathers of the neck-frill are very different, and the tail is much longer and more rounded. I shall not be surprised if another species of this peculiar form should be discovered; for I have in my possession the skin of a female from Bogota, which I am inclined to think is the female of an unknown species.
