following the example of our worthy President^ Lord Lilford, 

 who has recently had a decoy constructed for him near 

 Oundle, in Northamptonshire, by T. G. Skelton, one of tlie 

 celebrated decoy-making family. We heartily recommend 

 the bookj and hope it will be productive of good. 



90. Radde's Fauna and Flora of the South-western Casj)ia7i 

 District. 



[Die Fauna unci Flora des siidwestliclien Caspi-gebietes : wissenscliaft- 

 liclie Beitrage zu den Reisen an der Persisch-Russisclien Grenze. Von 

 Dr. Gustav Kadde. Leipzig : Brockhaus, 188G. 1 vol. 8vo. 420 pp.] 



Dr. Radde has_, perhaps wisely, issued in a separate volume 

 the systematic account of the zoological and botanical results 

 of his travels in the district adjoining the south-western por- 

 tions of the Caspian Sea, which border on the present frontier 

 between Russia and Persia. He had himself prepared the 

 portion relating to the Mammals, Birds, and Fishes of this 

 little-known region, besides the Botany, having obtained 

 the assistance of other well-known savants for the various 

 groups of Arthrozoa and MoUusca. As regards the Birds, 

 this part of the subject has been recently treated of very 

 fully in the author^s ' Ornis Caucasica,' published at Cassel 

 in 1884, In the present work we have therefore only a 

 list of the species as yet known to occur in " Talysch," as 

 this district is called, with remarks on their horizontal and 

 vertical distribution. The nomenclature and arrangement 

 of the ' Ornis Caucasica ' are adhered to. The species 

 included in the list are 312, and 40 'Warieties,^' i. e. sub- 

 species. The ' Ornis Caucasica ' gave us 370 species and 66 

 varieties. We observe that the Porphyrio of the Caspian is 

 still called '' veterum, S. G. Gmelin,-" although it has been 

 shown that that ancient naturalist never made such a name, 

 and, moreover, that the species in question is the Indian 

 P . polio cephalus [cf. Ibis, 1885, p. 111).
