Show 364 DR. ST. GEORGE MIVART ON THE SKELETON OF [May 7, above the lambdoidal ridge but more rounded and projecting below the latter, and paroccipital processes more sharply inclined backwards and also more distinct from the relatively smaller quadrates. T H E G E N E R A L DORSAL ASPECT of the skull (see fig. 3, p. 367) shows, compared with that of P. erithacus, a relatively short bony beak on account of the sharp vertical deflection of the latter towards its apex. The skull behind the cranio-facial articulation is flatter and the orbits somewhat more deeply incised, the deepest part of the incision being more preaxially situated in the orbital margin. The middle part of the hinder (occipital) margin presents a slight median concavity instead of an evenly and very slightly curved convexity. The dorsum of the skull is flatter antero-posteriorly than in P. erithacus. Fig. 2. Lateral aspect of skull of Psittacus erithacus. da. Depressed area in front of nasal aperture. (The other letters the same as in fig. 1.) THE GENERAL VENTRAL ASPECT (see figs. 6 & 7, p. 378) of the skull of L. fiavopedliatus is very similar to that of the skull of the Grey Parrot, but, as in the dorsal view, the bony beak forms a less proportion of it, as does the space occupied by the palatines, while the basis cranii is relatively more antero-posteriorly extended, the quadrates more anterior in position, while the very elongated lachrymal processes extend beside the zygomata for much more, instead of much less, than half the antero-posterior extent of the latter. T H E G E N E R A L A N T E R I O R ASPECT of the skull (see fig. 8,p. 382) of the Lory is very like that of P. erithacus, but the apex of the beak is more narrow7 and elongated, the nares looking more upwards and less outwards, the postorbital processes project less laterally, while the lachrymals are relatively broader, their processes more elongated, |
