Tue group which is characterized above, is at present composed of three well-defined species, according
accurately with each other in their general structure, and differing merely in slight, but still well-marked
modifications of specific character. From their comparative strength of body, the straight base and length-
ened shape of the bill, and the bold habits which are known to belong to one at least of the species, they
seem allied to that division of the Falconide which includes the Eagles ; while some of their minuter pecu-
liarities, particularly the rugose hexagonal scales of the acrotarsia, apparently bring them into immediate
alliance with the Ospreys, or the genus Pandion of M. Savigny.

Two specimens of the species now described have been examined ; one belonging to Mr. Gould’s original
collection, the second to a collection lately sent to this country by Mr. Hodgson, the British Resident at Nepal.
Both specimens correspond in their markings, but differ in size, the latter being about one fourth larger ; a
difference which may probably be attributed to sex. In both birds the colour of the back and wings is of an
intense brown. ‘The head is crested ; the feathers white at the base, of a dark brown nearly approaching to
black at the end, the hind ones being margined with a light rufous band at the apex. The wing-coverts near
the carpal joint are deep brown marked with small white spots; the quill-feathers fuscous, darker at the apex,
and marked with white towards the base of the interior web ; the cere, base of the beak and legs are yellow ;
the claws black.

The Plate represents the bird three fourths of its natural size.
