464 Recently published Ornithological Works. 



will form the thirty-niath volume of the seventh series of 

 the Memoirs of the Imperial Academy. 



The memoir is based upon the rich collections, now in the 

 Warsaw Museum, made by Dr. Dybowski and his companions 

 from 1865 to 1877 in various parts of Eastern Siberia, and 

 subsequently, during four years and a half, in Kamtschatka 

 and on the Commodore Islands. To these have been added 

 other collections made by M. Jankowski in the island of 

 Askold, and by M. Kalinowski in the marshes of the Sungari 

 and elsewhere. 



After a short introduction, in which the principal previous 

 authorities on the Siberian avifauna are mentioned, and an 

 account is given of the various explorations made and 

 localities visited by the above-mentioned collectors, the 

 author enters upon a systematic review of the numerous 

 species of the East-Siberian ornis. The Accipitres treated of 

 are 35, the Striges 17 in number. The rest of this volume 

 is devoted to the Passeres. Short Latin diagnoses are given 

 of every species. The work, when finished, will be one of 

 the most valuable of recent contributions to geographical 

 ornithology, and will be specially useful to students of the 

 European ornis, as showing clearly the ranges and the varia- 

 tions of the western species, as they extend eastwards.

[Travels amongst the Great Andes of the Equator. By Edward 

 Whymper. London : Murray, 1892.] 



Mr. Whymper^s account of his expedition to Ecuador in 

 1879-80, which has been so long waited for, has now ap- 

 peared, and, as those who know the author will have always 

 expected, leaves nothing to be desired as regards the accuracy 

 of its diction, the beauty of its illustrations, and the general 

 finish of the whole work. Mr. Whyraper's zoological col- 

 lections, which were formed with the view of bringing to- 

 gether the species which range highest in the Andes, chiefly 

 consisted of Insects, Crustaceans, and Reptiles, and are 

 described in a " Supplementary Appendix.'" But several
