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 antice ductis naresque ad- 

 umbrantibus instructum. Alee breviores, magis rotundatse ; pri- 

 mariis primo et secundo brevissimis, quinto longissimo. Tarsi 

 breviores. Digiti longiores ; externi inter se fere aequales. 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 Erythrodryas 



rosea.

Mr. Prince exhibited, on the part of Mr. Gould, two new species 

 of Australian Birds. These Mr. Gould characterizes as follows : — 



Astur cruentus. Ast. capite et occipite plumbeis ; torque nuchali 

 castaneo dorso, alis, cauddque eplumbeo-fuscis ; fusco colore apud 

 dorsum magis prcevalente, plumbeo apud ceteras partes ; remigum 

 primorum pogoniis internis ad basim albescentibus et plumbeo- 

 fasciatis ; corpore inferior e ferrugineo, fasciis crebris, angustis et 

 semicircularibus ornato. 

 Male. — Crown of the head and occiput dark slate -colour ; sides of 

 the face grey ; at the back of the neck a collar of chestnut-red ; back, 

 wings and tail slaty brown, the brown hue predominating on the 

 back and the slate-colour upon the other parts ; inner webs of the 

 primaries fading into white at the base, and crossed by bars of slate- 

 colour; the interspaces freckled with buff; inner webs of the tail- 

 feathers marked in a precisely similar manner ; chin buffy white ; all 

 the under surface rust-red, crossed by numerous narrow semicircular 

 bands of white ; irides bright yellow ; cere dull yellow ; bill black at 

 the tip, blue at the base ; legs and feet pale yellow ; claws black. 

 Total length, 14± inches; bill, f ; wing, 7 ; tail, 6 ; tarsi, 2j. 

 Hab. Western Australia. 



This species is intermediate in size between Astur approximans 

 and Accipiter torquatus, but is of a more grey or blue colour on the 

 back, and has the transverse lines on the breast narrower and more 

 rufous. 



Lobivanellus personatus. Lob. vertice et occipite nigerrimis ; 

 faciei lateribus nucha, uropygio, et corpore inferiore albis ; dorso 

 et plumis scapularibus pallide fuscescenti-cinereis ; paleis penden-
