Show 1895.] ON THE SKELETON OF LORIUS FLAVOPALLIATUS, ETC. 363 4. The Skeleton of Lorius flavopalliatus compared with that of Psittacus erithacus.-Part II. By ST. G E O R GE MIVART, F.R.S. [Received M a y 1, 1895.] In a preceding paper1 I described the postcranial part of axial skeleton of Lorius flavopalliatus and Psittacus erithacus. I now proceed to describe the characters presented by the skulls of those two species. THE SKULL. General Description. Fig. 1. sFh \ c clot Lateral aspect of skull of Lorius flavopalliatus. da.

T H E GENERAL LATERAL ASPECT of the skull of Lorius flavopalliatus (compared with that of P. erithacus) shows a cranium rather more flattened, a relatively somewhat more slender and elongated bony beak, a more nearly enclosed orbit, palatines which do not descend beyond the level of the ventral margins of the quadrates, an occiput which is less rounded and more sharply inclined preaxiad 1 See P.
