ne. Thisalso apphes to either crotaphyte fossa, which latter is well shownin fig. I of Plate IV. Within either capacious orbit, the foramen rotundum is circularand thoroughly circumscribed by bone ; the large foraminalopening above it merges with the corresponding one of the otherorbit, the two together robbing the anterior wall of the brain-caseof a large part of its osseous partition. The mesial ethmoidal mass is markedly extensive and spreading,forming a broad base for the frontal roof above. Its anterioredge forms the posterior Hne of the cranio-facial hinge in frontof it. Laterally and mesially, the body of the lacrymal, the parsplana, and the mescthmoid are so thoroughly fused together thatall sutural lines of demarcation have been entirely obliterated inthis adult skull. Mesially, the mesethmoid is raised into asharpened crest, which is extended posteriorly over the sphenoidalrostrum to the mid-anterior angular projection of the basi-temporal area.

XX 191S J -^ ^ y u The sderotal plates of the eyeballs that belonged to this speci-men have apparently been lost, so I am unable to describe them. Posteriorly, the rhinal chamber is largely filled by bone,it being co-ossified with the internal lateral and superior walls.Inferomesially, it develops a sharp spine, which projects anteriorlyinto the forepart of the chamber. The narial apertures are sub-circular in outhne, and open internally, side by side, just oppositethe inferior line of the cranio-facial hinge. As in the majority of Parrots, the palatines are big, strongbones. Anteriorly, they are more or less rod-hke, being at firsttransversely flattened, to become compressed in the oppositedirection at their distal terminations. Posteriorly, either boneis an extensive blade—^broad, and with rounded margins. Whenarticulated, this portion is directed downwards and backwards,curling inwards above, to articulate with the
