440 THE ZOOLOGIST. 



in some of the ornithological secrets of Siberia in Europe being 

 unravelled. 



The portraits given are the strength of the illustrations ; it 

 is pleasant to see the features of colleagues with whom one is 

 unacquainted, and of whom we may have formed an erroneous 

 impression. There is often much friction among naturalists, 

 and much of it might be avoided or reduced by a little personal 

 knowledge or acquaintance. 



Genera Avium. Edited by P. Wytsman. Parts 1-5. Brussels : 

 Verteneuil & Desmet. 

 This work, which is to be published entirely in the English 

 language, has secured the co-operation of P. L. Sclater, E. B. 

 Sharpe, W. R. Ogilvie- Grant, E. Hartert, E. Hellmayr, T. Salva- 

 dori, and other ornithologists, and promises to be a work of 

 considerable importance. Five parts have reached us, each with 

 a coloured plate, and following the plan of the publication, viz., 

 each family to appear separately with separate pagination, and 

 the history of its classification to be given with synoptical tables 

 of the genera (or subfamilies) ; a description of each genus, and 

 a list of species, subspecies, and varieties, with bibliographical 

 references and details of geographical distribution. The draw- 

 ings are made by M. Keulemans, and no effort to obtain accuracy 

 and to bring up the work to date has been spared.
