Recently published Ornithological Works. 551 
labe,' and Kubary, whose collections were worked out by 
Dr. Finsch (P. Z. S. 1880, p. 574), are the only previous' 
authorities on the birds of Rule. Mr. 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 Tephras ruld 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 semperi owsloni, which represents Z. semperi 
of the Pelews in Ruk, and incidentally describes two new 
subspecies of Finches as Erythrura irichroa papuana , from 
New Guinea, and E. trichroa woodfordi, from the Solomon 
Islands. Many notes on the eggs and nests are given in 
this paper. 
82. Hartert on the Birds of Rammer Island. 
[The Birds of Dammer Island, in the Banda Sea. By Ernst Hartert. 
Nov. Zool. vii. p. 12 (1900).] 
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 surveying-ship ‘ Penguin' in 1891, and the ten species 
of birds of which examples were obtained on that occasion 
have been enumerated by Dr. R. R. Sharpe (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 australasice dammeriana , and Chrysococcyx rufomerus 
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.
