Tue present species, while it is closely allied in form to the last-figured bird, and most strictly connected with the natural division alluded to in the preceding description, offers some essential marks of distinction in the plumage ; one of the most conspicuous of which is the different characters of the feathers on the breast, which are marked by beautiful and regular scales, while in the Piews occipitalis an uniform and totally different colouring prevails on the same parts. To this character the bird owes its specific name. _ Its locality is believed, like that of Picus occipitalis, to be confined solely to the higher parts of the mountains. The top of the head, and occiput are scarlet ; above and below the eye passes a yellowish white streak ; a black line extends also from the base of the lower mandible along the sides of the neck ; the upper surface is of a bright green colour; the quill-feathers and tail dull olive black barred with white; the throat and breast are greyish green; the abdomen and under surface of a still lighter tint elegantly marked with black scales, closely and regularly disposed ; the bill is yellowish white, becoming horn-brown at the base ; the tarsi are brown. The figure is of the natural size.
