On several New Species of Birds from various parts op 

 THE World. By John Gould, V.P., F.R.S. etc. 



Mr. Gould called attention to three species of Australian birds 

 collected by Mr. Elsey during the recent expedition under A. C. 

 Gregory, Esq., from the Victoria River on the north-west coast to 

 Moreton Bay : two of these birds were of especial beauty and in- 

 terest, viz. a Psephotus and a Malurus. The former is allied both 

 to the P. pulcherrimus and P. multicolor, but differs from either, 

 among other characters, by the rich yellow mark on the shoulder ; 

 and the Malurus is distinguished from all the other members of its 

 genus by its larger size and by the beautiful lilac circlet which 

 adorns the crown. The third species alluded to was a Petroica, 

 allied to the P. superciliosa, a bird discovered by the late Mr. Gilbert 

 in the neighbourhood of the Burdekin Lakes, and which with the 

 present would admit of separation from the other species of the 

 genus. 



For the Parrakeet Mr. Gould proposed the name of 



PSEPHOTUS CHRYSOPTERYGIUS.

 posterior angle, very pale yellow ; on the centre of the crown a patch

 verditcr blue, somewhat greener on the cheeks and upper tail- coverts ; 

 immediately below the eye a tinge of yellow ; back of the neck, 

 back and scapularies, light greyish-brown, slightly tinged with green ; 

 shoulder and lesser wing-coverts fine yellow ; primaries and se- 

 condaries black, margined externally with blue ; feathers of the lower 

 part of the abdomen, vent, and under tail-coverts, light scarlet, mar- 

 gined with greyish green ; two centre tail feathers dark green at the 

 base, passing into deep blue towards the extremity, and tipped with
