labe/ and Kubary, M'hose collections were worked out by 

 Dr. Finsch (P. Z. S. 1880, p. 574), are the only previous 

 authorities on the birds of Ruk. IMr. Hartert now writes on 

 the large collections made there and transmitted to Tring 

 by Mr. Alan Owston, of Yokohama, of which the most im- 

 portant features are the new Tephrus riiki and a fine series 

 of eggs and nests. Altogether 35 species of birds are now 

 known from this island. Mr. Hartert makes a new sub- 

 species, Zosterops semjjeri oivstoni, which represents Z. semperi 

 of the Pelews in Ruk, and incidentally describes two new 

 subspecies of Finches as Erythriira irichroa papuana, from 

 New Guinea, and E. irichroa woodfordi , from the Solomon 

 Islands. Many notes on the eggs and nests are given iu 

 this papei". 



82. Hartert on the Birds of Dummer hi and. 



[The Birds of Dammar Island, in the Banda Sea. By Ernst Hartert. 

 Nov. Zool. vii. p. 12 (11100).] 



Dammer is a volcanic islet halfway between Timor and 

 Timorlaut, less than ten miles in length and five in width, and 

 almost entirely covered by dense vegetation. It was visited 

 by the surveyitig-ship ' Penguin" in 1891, and the ten species 

 of birds of which examples were obtained on that occasion 

 have been enumerated by Dr. R. B. Sliarpe (Ann. & Mag. 

 N. H. (6) xiv. p. 56, 1894). Mr. Hartert now treats of the 

 birds collected on Dammer by Mr. H. Kuhn and sent to 

 Tring in 1899, and refers them to 49 species, amongst 

 which Gerygone kuehni, Pachycephala melanura dammeriana, 

 Halcyon australasiee dammeriana, and Chrysococcyx rafomeru» 

 are now described as new species or subspecies. Mr. Hartert 

 thinks that some of the species hitherto only known from 

 Dammer may likewise be met with on the neighbouring 

 Serwatty group when it has been thoroughly explored.
