Ale longiores et minis concave. Cauda magis quadrata. Tarsi 
breviores. Digiti longiores. 
Types.—Platycercus scapulatus and erythropterus, which will now 
stand as Aprosmictus scapulatus and A. erythropterus. 
The other birds which Mr. Gould proposed to form into a new 
genus are the Petroica rhodinogaster of Messrs. Jardine and Selby, 
and the Petroica rosea of himself. These birds are much more ar- 
boreal in their habits than the true Petroicas, which are expressly 
adapted for the ground, while these are equally so to the thick 
brushwood, to the deepest gullies among which they usually resort. 
For this group he proposed the designation of 
ERYTHRODRYAS. 
Gen. Char. fere ut in Petroicd.—Rostrum attamen brevius, ad basim 
magis depressum, et vibrissis tenuibus anticé ductis naresque ad- 
umbrantibus instructum. Ale breviores, magis rotundate; pri- 
mariis primo et secundo brevissimis, quinto longissimo. Tarsi 
breviores. Digiti longiores ; externi inter se feré equales. Ungues 
acutiores et magis incurvati. 
Type.—Erythrodryas rhodinogaster (Petroica rhodinogaster, Jard. and 
Selb.). 
To this genus also belongs the species characterized by him in the 
Proceedings of the Zoological Society for 1839, p. 142, under the 
name of Petroica rosea, which will now stand as Hrythrodryas 
rosea.
