 Inhab. Marquesas Islands. 



I look upon this bird with great interest, since it forms an additional species 

 of a limited but very beautiful group of the Psittacidae, whose natural habitat 

 seems to be confined to the islands of the Southern Ocean. 



From the indistinct character of the markings of the throat and abdomen, 

 the bird from which the above description was taken would appear to be some- 

 what immature. 



The figures are about two-thirds of the natural size.
