The head and neck yellow; the upper parts olive-green, tinged with grey ; the wings and tail blackish-brown; the first row of small coverts, and the secondary coverts, tipped with whitish, the quills and tail- feathers margined with light greenish-grey.

Length to end of tail 7 inches ; bill along the ridge 7^ lines, along the edge of lower mandible 7^ lines; wing from cubitus 3| inchei; tail 2^; tarsus 10^ lines; hind toe 4^ lines, its claw 6 lines; middle toe 8 lines, its claw 4 lines.
