have further distinguished T. rubidiventris of Nipal and Sikirn. from 

 P. melanolophus, Vigors, of the Simla and Masuri mountains; with 

 which the P. melanolophus of Jerdon's catalogue still requires to be 

 critically compared. 



Another bird-novelty is a strongly marked species ofParrakeet, which 

 I procured and kept for some time alive ; but the specimen is now added 

 to the museum. 



Pal^iornis viridimystax, nobis. Size about that of P. malaccensis ; 

 closed wing 6 in. Colour bright golden-green, the green deeper than 

 usual in this genus, with light indigo-blue on the primaries and tail : 

 axillaries, and fore-part of the wing uuderneath, bright yellow : a broad 

 band of peach-blossom red below the eye, from bill to middle and lower 

 portion of ear-coverts; rest of the latter green tinged with verditer; 

 moustachial streak as in P. malaccensis and others, but of a darkish 

 green hue, contrasting with the more yellowish green of the body : a 

 slight pale duskyish streak also from nostril to eye ; and small red spot 

 above the eye (conspicuous in the living bird). Bill duskyish in the indi- 

 vidual, but with the upper mandible doubtless coral-red in the adult. 

 Irides dark greenish-hazel, surrounded by a white ring. Feet pale green- 

 ish-grey. Habitat unknown. 



As an interesting acquisition to our bird-collection, may also be men- 

 tioned a fine specimen of the great Black Cockatoo of N. Guinea (Micro- 

 glossum aterrimum?*), which was brought dead, affording the oppor- 

 tunity of examining it fresh. This bird is remarkable for its enormous 

 beak, and the great ' tooth' or process on the upper mandible ; but its 

 tongue is not particularly small, as the generic name imports. The figure 

 in Edwards's ' Birds' gives a better idea of the species than any other 

 which I have seen. 



Some recent observations lead to the opinion that the great Sulphur- 

 crested White Cockatoo of N. Guinea is distinct from that of JN". S. Wales. 

 A fine living specimen of the latter (Cacattja galerita vera) entirely 

 corresponds with Mr. Gould's figure of the species in the ' Birds of Aus- 

 tralia/f having the bare skin surrounding the eye pure white, or with an 



* I am aware that two species have been discriminated ; but not of their dis- 

 tinctions. 



f "If," remarks Mr. Gould, "we regard the White Cockatoo of Van Diemen's 

 Land, that of the continent of Australia, and that of New Guinea as mere varieties 

 of each other, this species has a more extensive range than most other birds. It 

 is an inhabitant of all the Australian colonies, both on the southern and northern 

 coasts, but has not yet been observed on the western.
