49. Seebohm's ' Monograph of the Thrushes' 



[A Monograph of the Turdid«, 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 I. Imperial 4to. London : 

 Henry Sotheran & Co., 1898.] 



We are much pleased to have before us the first part of 

 the long-expected ' Monograph of the Thrushes/ upon the 

 preparation of which our late friend and colleague Henry 

 Seebohm was engaged for many years, but which was 

 unfortunately left unfinished at the time of his decease. 

 Messrs. Henry Sotheran & Co., having acquired the whole 

 stock of the work, have "^^secured the co-operation of Mr. See- 

 bohm's old friend, Dr. Bowdler Sharpe/' ^^to superintend 

 the publication of the work on the lines indicated by the 

 author." The plates were all drawn by Keulemans under 

 Seebohm's eyes, and those now before us are examples of 

 that artist's well-known talents. The work will be issued in 

 twelve parts in imperial quarto, at intervals of two montlis. 



The following species are figured in the first part : — 

 Geocichla varia, G. hancii, G. dauma, G. pai'virostris, G. nil- 

 (/iriensis, G. imbi'icata, G. horsfieldi, G. heinii, G. papuensis, 

 G. cuneata, G. lanulata, G. macrorhyncha, G. dixoni, G. mol- 

 lissima, G. spiloptera, G. princii, G. guttata, G. gurneyi, 

 G. crossleyi.

[Hybrids between the Game-cock and the Guinea-fowl. By Juan 

 Vilaro, M.D. Bull. Amer. Mus. Nat. Hist. ix. p. 225, 1897.] 



The pugnacity of the Game-cock is notorious, while those 

 persons who have kept Guinea-fowls are aware that both 

 male and female members of the genus Nuinida are of a 

 quarrelsome and aggressive disposition. Of four hybrirls (in 

 which the father was the Game-cock), three Mere males, but 

 had no spurs, while the fourth was a female ; and all of them 

 were so outrageously vicious — the hen being the worst — that 

 they had to be destroyed. The cocks did not crow, but 

 emitted a feeble chirping. The plumages are described in
