17. Radde on the Birds of the Caucasus. 



[Vierter Naclitrag zur Ornis Caucasica. Von Dr. Gustav Radde in 

 Tiflis. Ornis, vi. p. 400 (1890).] 



In tlie new number of ' Ornis ' will be found a " fourth 

 supplements^ by Dr. Radde to his 'Ornis Caucasica.^ It 

 contains a number of interesting notes upon the birds of this 

 country "^ by the author and his assistant workers on the 

 Caucasian avifauna. A fifth supplement is promised to 

 appear shortly. Dr. Radde^s so-called '' Porphyrio veterum " 

 (well-figured in ' Ornis Caucasica/ pi. xxiv.) from the Len- 

 koran district is, we believe, identical with the Indian P. 

 polio cephalus. It has been already shown (Ibis, 1879, p. 195) 

 that there is no such name as "veterum, S. G. Gmelin;" and, 

 as Mr. Seebohm has stated (Ibis, ISS-l, p. 429), the Caspian 

 bird (which the traveller S. F, Gmelin referred to as the 

 '^ Porphyrio" of the ancients) is the same as the Indian species, 

 and quite distinct from P. cceruleus of Southern Europe. 



18. Ramsay on the Birds in the Australian Museum. 



[Supplement to the Catalogue of the Australian Accipitres, or Diurnal 

 Birds of Prey, in the Collection of the Australian Museum at Sydney,

 Catalogue of the Australian Striges, or Nocturnal Birds of Prey, in the 

 Collection of the Australian Museum at Sydney, N. S. W. By E. P. 

 Bamsay, LL.D., Curator, 8vo. Sydney : 1890.] 



Dr. Ramsay has now resumed the publication of his cata- 

 logue of the specimens of birds in the Australian IMuseum, 

 Sydney, and has issued a supplement to the catalogue of 

 Accipitres published in 1875, and a catalogue of the Striges. 

 The first of these contains accounts of additional specimens 

 of 9 species, amongst which are many in nestling-plumage. 

 The Australian Owls all belong to two genera — Strix and 

 Ninox — according to Dr. Ramsay's views. Of Strix he recog- 

 nized 4 species and 2 subspecies ; of Ninox 9 species. Of the 

 latter genus two recently described species are N. peninsularis, 

 of Cape York, and N. albaria, of Lord Howe Island. The Aus- 

 tralian IVIuseum does not appear to contain specimens of these 

 forms, and in most cases the list of specimens is not very long.
