Recently published Ornithological Works. 757 
volume of this most useful work, which also, according to 
the present arrangement, forms part of the f International 
Catalogue of Scientific Literature/ was issued in December 
1909. As in the preceding years, the section “Aves,” in 
which we are specially interested, was compiled by the late 
Dr. Dowdier Sharpe (with, we believe, the able assistance of 
Mr. Charles Chubb), and was one of the last pieces of good 
work that our much lamented friend performed*'. 
The Record of “ Aves” commences, as usual, with a List of 
the Titles of all works and memoirs relating to Ornithology 
issued in 1908, arranged in alphabetical order under the 
authors’ names. The Titles are 1949 in number. The 
corresponding number of Titles in 1907 was 1 716. 
Next to the “ List of Titles ” comes the “ Subject Index/’ 
divided up, as we think, into too many heads, and concluding 
with the Geographical Index. In the “ Subject Index ” the 
titles are not fully repeated, but conveniently referred to by 
the name of the author and the number of his book or 
memoir in the “ List of Titles.” 
The third section of the Record of “Aves” is very 
important for workers in Systematic Ornithology, as it 
tells us what has been done during the past year in each of 
the Orders of Birds arranged according to Dr. Sharpe’s 
own system, and in each Family of the Passeres. For 
example, if working at Paradise-birds, one has only to 
turn to “ Paradiseidse ” in the Systematic Index to find 
references to the various publications of 1908 in which 
information has been given on this group and the names of 
the newly described species. This, we need hardly point out, 
is a very great convenience to working writers in Ornithology. 
Mr. W. L. Sclater, F.Z.S., M.B.O.U., has been appointed 
to succeed the late Dr. Bowdler Sharpe in preparing the 
section “Aves” for the Zoological Record, and is now at 
work on the ornithological literature of 1909. 
* Altogether Dr. Sharpe prepared the Reports on u Aves ” in twenty- 
five of the forty-fiye volumes of the ‘ Zoological Record.’
