462 THE NATUEAL UISTOET EEVIEW. 



corded by Swinlioe, as a " common summer visitant to tlie whole of 

 China.'-'* 



Of the genus Turdus Eadde records 7 species as met with in 

 these countries, amongst which are several known as rare and 

 occasional visitajits to Europe, but of which Eastern Siberia is the 

 true home. And here we may remark that Herr Eadde has as 

 we believe, committed a serious error in identifying Turdus naumanni, 

 Temminck, so well distinguished and illustrated in the last supple- 

 mentary volume of Naumann's Yogel Deutschlands with Turdus ruji- 

 eollis of Pallas ; the latter being a very distinct species more nearly 

 allied to Turdus atrigularis. Nor can we believe that the bird figured 

 on plate viii. of his work is really a bastard between Tfuscatus andT. 

 rvficollis. It appears to us to be nothing more than a young Turdus 

 naumanni. Although the young birds of the latter species are 

 somewhat difficult to distinguish from those of Tfuscatus, yet a large 

 suite of specimens renders this task comparatively easy, as we have 

 occasion to know from our examination of the very extensive series 

 of thrushes procured by Mr. Swinhoe in various parts of China. 



The true Singers, in which division Herr Eadde places the genera 

 Accentor, Saxicola, Sylvia, Begulus, Zosterps^ Salicaria, Muscicapa, 

 and Lanius, number 43 species in South-eastern Siberia. To this 

 group one of the few supposed novelties obtained by our author 

 belongs — namely, a new Fhyllopneuste allied to P. sihirica, and pro- 

 posed to be called P. schwarzi. This, however, may very probably 

 be the same as one of the several new species of this form obtained 

 by Mr. Swinhoe in China, and previously described in this country — 

 it would be difficult to say which without actual comparison of spe- 

 cimens. The list of Passerine birds of Eastern Siberia is closed with 

 the Swallows, of which four species are included in Herr Eaddc's 

 work. 



The next order of birds, the Gallinacea?, among which our author 

 includes the Pigeons, numbers 18 species in this Fauna. Of these, 

 perhaps the most remarkable is the Pallas, or Three-toed Sand-grouse, 

 (^Syrrlmptes paradoxus), which has of late years created so much 

 excitement in Europe by appearing in large flocks all over the 

 westernmost parts of our continent, even up to the shores of the 

 Atlantic. t This species is at the same time one of the most
