ings are broadly margined \vith silvery vvhite ; and there are, in ad- 

 dition to the spots of the upper surface, a small round spot in the 

 cell close to the base, and an oval one above the first median ner- 

 vule near its origin, both black with a silvery border. Beyond the 

 middle is a silvery \vhite irregular band, narrowed on the costa, where 

 it is marked by four black dots, the third and fourth indistinct, 

 broadest on the inner margin, \vhere it becomes of a pearly hue. 

 Between this band and the margin the prevailing colour is a pale 

 fulvous. A band composed of a series of silvery grey lunules com- 

 mences on the costa and terminates on the submedian nervure. 

 These lunules have their points directed inwards, and are margined 

 intemally ■vvith black, those nearest the costa less broadly than the 

 others. The terminations of the nervules are bordered with silvery 

 grey, and beyond this with black, and the cilia are spotted with the 

 šame colours. The posterior \vings are bright deep fulvous, paler 

 tovvards the outer margin, traversed beyond the middle by a flexuous 

 silvery band. At the base, before the precostal nervule, is an oval 

 black spot bordered vvith silvery -vvhite ; beyond this is a macular 

 band composed of four black transverse vittae bordered vvith silvery 

 vvhite, extending from the costa to the abdominal fold ; the inner 

 vitta transverse only at its origin, extendiug dovvn the abdominal to 

 unite vvith a similar fold vvhich traverses the cell and descends ob- 

 liąuely betvveen the first median nervule and the submedian nervure. 

 The inner margin of the silverj'^ band is marked vvith a series of bJack 

 spots and vittse, and the abdominal fold is beautifuUy marked vvith 

 ai tematė silvery, bright fulvous and black vittae. Near the outer 

 margin is a broad silvery vvhite band sprinkled vvith grey and ful- 

 vous scales, and clouded vvith these colours, bordered externally vvith 

 black. On the outer margin itself is a narrovv black border, mar- 

 gined intemally vvith vvhite. Cilia, except on the tail, vvhite. 



Head fulvous. Thorax fulvous above, streaked below vvith fulvous 

 and vvhite. Legs vvhite.

5. Description of Strigops habroptilus. By G. R. Gray, Esq., 

 F.L.S. &c. 



With reference to the interesting particulars about Strigops habro- 

 ptilus, communicated by Mr. Gould (supra p. 50), I am induced to 

 remark that this singular bird was first noticed under the native name 

 of Kakapo in the Appendix to Dr. Diefiįnbach's Travels in New 

 Zealand, vvhere it vvas suggested to belong to the family of Cuculidce, 

 from the supposed similarity of the few feathers brought by that 

 gentleman to those of the genus Centropus. This idea vvas at once 

 dispelled by the arrival of the perfect specimen novv in the British 

 Museum, from vs-hich a figure vvas made by my friend Mr. Mitchell, 

 and published as pi. 105 in the ' Genera of Birds.' The singular ap- 

 pearance of the feathers of the head, and especially their arrange-
