We are much pleased to find that a complete account of 

 the valuable zoological results of Prjevalski's expeditions 

 into Central Asia has been planned and commenced. It will 

 be issued by the I. Academy of Sciences of St. Petersburg, 

 at the cost of the Crown Prince Nicholas, who could hardly 

 have devoted his means to a more worthy object. The 

 second volume, devoted to the birds, is being prepared by 

 Herr Th. Pleske, who is in charge of the Bird-Collection of 

 the Academy's Museum, and the first livraison is now 

 before us. 



The present number commences with the Turdoid Passeres, 

 and treats of the genera Turdus, Cinclus, Saxicola, Ruticilla, 

 and their allies. The text is in Russian and German, in 

 parallel columns, and is thus accessible to the whole civilized 

 world. Detailed lists are given of the specimens of each 

 species obtained by Prjevalski. The following species are 

 figured in this part : — 



Plate I. : Pratincola insignis, Calliope tschebaiewi, and 

 Dumelicola major. 



Plate III. : Arundinax aedon, Herbivocula armandi, H. in- 

 dica, H.fuscata, and H. affinis.
