On a new Genus mid Species of Parrakeet (Geopsittacus occiden- 

 talis, Gould) from Western Australia. By John Gould, F.R.S. 



All the upper surface grass-green, each feather crossed by irregular 

 bands of black and greenish yellow ; feathers of the crown and nape 

 with a streak of black down the centre ; throat and breast yellowish 

 green, passing into sulphur-yellow on the abdomen ; spurious wings 

 brown ; primaries and secondaries brown, narrowly fringed with a 

 greenish hue on their external webs, with the exception of the first 

 three ; the primaries and secondaries have also an oblique mark of 

 yellow near their bases, which mark increases in breadth and in depth 

 of colour as the feathers approach the body ; two centre tail-feathers 

 dark brown, toothed on the edge of both webs with greenish-yellow ; 

 the next on each side dark brown, toothed on the outer web only 

 with brighter and longer marks of yellow ; the remainder dark brown, 

 crossed bj^ bands of yellow, which in some cases are continuous across 

 both webs, and in others alternate ; under tail-coverts sulphur-yellow, 

 crossed on their outer webs with narrow oblique and irregular bands 

 of blackish brown ; bill horn ; feet fleshy. 



Total length 1 inches, bill ^, wing 5^, tail 5, tr.rsi i. 



Hab. Western Australia. 



Remark. — At a first glance this bird has the appearance of a Pezo- 

 porus formosus with an undeveloped tail ; but on a careful com])ari- 

 son it is found not only to differ from that species in some parts of 

 its colouring, but also in form — sufficiently so, indeed, to warrant the 

 opinion that it will be necessary to make it the type of a new genus. 

 Its whole contour and colour reminds one of Strigops. The points 

 in which it differs from Pezopo7'us are the possession of a thick 

 bluffy head, larger and more swollen nostrils, the total absence of 

 any red mark on the forehead, a much larger wing with more 

 rounded primaries, a very short tail the two centre feathers of which 

 are much shorter than the two next on each side, and, lastly, in 

 having very differently formed feet, with short and feeble nails, 

 whereas in Pezoporus they are prolonged and slender. For this new 

 bird I propose the generic name of Geopsittacus, with that of occiden- 

 talis as its specific designation. — Proc. Zool. Soc. March 12, 1 8(11.
