102. Seebohm's 'Monograph of the Thrushes' 



[A Monograph of tho TurdidjB, or Family of Thrushes. By the late 

 Henry Seebohm. Edited and completed (after the Author's death) by 

 R. Bowdler Sharpe, LL.D., F.L.S., &c. Part VI. Imperial 4to. 

 London: Henry Sotheran & Co., 1899.] 



The following species are figured in the sixth part of 

 the Monograph of the Thrushes^ which advances steadily 

 towards completion : — Tardus confinis, T. miyratorius, T. ruji- 

 venter, T. magellanicus, T. falklandicus, T. flavirostris, 

 T. graysoni, T. chiguanco, T. tephronotus, T. olivaceus, 

 T. abyssinicus, T. elgonensis. 



The preseiit part begins with the " Robin " group of North 

 America — Tardus migratorius and its allies — and then passes 

 to the South-American T. rufiventer and T. magellanicus ; 

 but we do not quite understand how T. chiguanco comes in 

 here_, for its true place is surely near T. fuscater and T. gigas. 

 The monograph then proceeds to the African group which is 

 typified by T. olivaceus, and four species are figured.

[A Study of the Type Specimens of Birds in the Collection of the 

 Academy of Natural Sciences of Philadelphia, with a brief History of the 

 Collection. By Witmer Stone. Proc. Ac. Nat. Sci. Philad. 1899, p. 5.] 



This is a useful and important paper, containing a com- 

 plete list of the types in the famous collection of birds 

 belonging to the Academy of iMatural Sciences of Phila- 

 delphia, and a good historical account of the way in which 

 the collection was formed. In 1856 it was stated by Sclater, 

 who had devoted several weeks to its examination, that, in 

 his opinion, this collection of birds was sujierior to that of 

 any other museum then existing. Among the many liberal 

 contributors to this splendid series, which was estimated in 

 1860 to contain some 26,000 specimens, the chief donor was 

 the late Dr. Thomas B. Wilson, at one time President of the 

 Philadelphia Academy. Dr. Wilson purchased in Europe 

 tlie large collection of Victor Massena, Due de Ilivoli, the 

 Bourcier collection of Parrots and Tanagers, the large col-
