Hartert on the Types at Tring. 
[Types of Birds in the Tring Museum. By Ernest Hartert, Pli.D. 
-B. Types in the general collection. Nov. Zool. xxvi. pp. 123-178, 
1919, and xxvii. pp. 425-505, 1920.] 
Dr. Hartert has already rendered a great service to 
ornithology by his Catalogue of the types in the Brelim 
collection, chiefly of Palsearctic forms (Nov. Zool. 1918, 
pp. 4-63). He has now in the papers before us commenced 
to list those in the general collection, and although he has 
enumerated 878 he has not completed the Passeres. 
This is a striking testimony to the value and completeness 
of the collections in the Tring Museum gathered together in 
so comparatively short a space of time by the enthusiasm of 
Lord Rothschild and Dr. Hartert. 
The majority of the birds described from the Tring 
collections are naturally those named by Lord Rothschild 
and Dr. Hartert themselves, though a good many have been 
described by Drs. Hellmayr, Neumann, and Stresemann 
and others who have worked at Tring. 
There are also a number of types which have been acquired 
with collections which had already been described elsewhere. 
The names which are now regarded as synonyms are marked 
with a dagger (f), and appear to be very few compared with 
those that are considered valid; while there are quite a 
number of new subspecies and names mentioned for the 
first time, which must be carefully noted by the working 
ornithologist. 
Kuroda on new Japanese and Formosan birds. 
[Descriptions of three new forms of birds from Japan and Formosa. 
By Nagamichi Kuroda. Dobuts. Zasshi, xxxii. pp. 243-248, 1920.] 
The birds described are Milvus lineatus formosanus from 
Formosa, distinguished from the mainland form by its 
smaller dimensions ; Nyroca ferina ferinoides from Japan 
in winter, probably breeding in south-eastern Siberia. It 
differs from the Common Pochard by its shorter wing, 
which measures 203-210 mm. as against 213-224 mm,
