Hartert on the Types at Tring. 



[Types of Birds in tlie Tring Museum. By Ernest Hartert, Ph.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 Brehm 

 collection, chiefly of Palrearctic 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 Stresemanri 

 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. Debuts. Zasshi, xxxii. pp. 243-24:8, 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 Ji03-210 mm. as against 213-224 mm.
