374. Calyptorhynchus Baudinii, Vig. ; : : : : : : : d 3 : Wol, W. JA, 13

Inhabits Western Australia, and is distinguished by its small size and by the white marks on the tail.

Genus CatLocernaton, Less.

Of this form only a single species is known.

 

375. Callocephalon galeatum  . : : : : : : : Wolk We JB ii,

Inhabits the southern coast of Australia and Van Diemen’s Land.

Genus Potyrenis, Vag.

This genus comprises two species, both of which are peculiar to the southern portions of Australia. They

have many characters common to, and resemble in appearance, the Palgorni of India.

Genus Aprosmicrus, Gould.
Generic characters.
As in Platycercus, but the bill more feeble; cere and nostrils covered with fine hair-like feathers ; wings longer
and less concave ; ¢ail more square; tars? shorter and toes longer than in that genus.
Two, if not three species of this form inhabit Australia, and others are found in New Guinea and the
neighbouring islands. They are distinguished from the Platycerci by the possession of a well-developed os
Jurcatorium, a bone which is entirely wanting in the members of that genus ; in their habits they are mainly

arboreal, and in their disposition are morose and sullen.

378. Aprosmictus scapulatus . : : : : : : : ; : : ‘ Wok We Jel, Wy.

This species appears to be confined to New South Wales.

379. Aprosmictus erythropterus : : : : : : ; Vor Vie ri 1s.

The red-winged Parrakeets from the north coast are nearly a fourth smaller than those inhabiting the Liver-

pool plains and similar districts of the south coast ; are they varieties of each other or distinct species ?

Genus PLarycercus, Vig.

In my opinion the New Zealand birds that have been placed in this genus are not true Platycerci, all the
known species of which are confined to Australia; they comprise fourteen species which appear to be naturally
divisible into minor groups, to which generic appellations may hereafter be given; for instance the P. semitorquatus,
P. Baueri, P. Barnardi, &c. form one; the P. Adelaidie, P. Pennantu, P. flaveolus, P. Jlaviventris, &c. form another :
P. eximius, P. splendidus, P. icterotis, &c. form a third; and P. pileatus a fourth.

The members of this and the two next genera lay from seven to ten eggs in the holes of trees.
