190 THE ZOOLOGIST. 



Alphabetique des Personnes avec lesquelles nous avons corres- 

 pondu au sujet des Hybrides" is a most representative one, 

 including many of our own contributors, some under a new 

 appellation, as, for example, the Curator of the Leicester Museum, 

 who appears as " pasteur a Rotterdam (Hollande)." 



Neither time, trouble, nor expense has evidently been with- 

 held in the production of this book, which incorporates a large 

 amount of scattered information in a systematic and judicial 

 manner, and will for a long time prove a recognized reference to 

 a most important factor in zoological philosophy. 



A Dictionary of Bird Notes, to which is appended a Glossary of 

 Popular, Local, and Old-fashioned Synonyms of British 

 Birds. By Chas. Louis Hett. Jacksons', Market Place, 

 Brigg. 

 In these pages (1897, p. 505) we published an announcement 

 by Mr. Hett that he was preparing a Dictionary of the Call-notes 

 of British Birds, and we have now received a tasteful and in- 

 expensive book — interleaved for the record of observations by the 

 reader — which may well find a place in the ornithological library. 

 The method pursued is as follows : — Firstly, under " Note-Bird" 

 an alphabetical list of the notes, with the name of the avian 

 vocalist attached, is given, and then, under " Bird-Note," the 

 arrangement is reversed. Easy reference is thus afforded, and 

 the equivalents of the sounds themselves will and must be judged 

 by specialists in the appreciation and interpretation of bird-notes. 

 The Glossary of Popular, Local, and Old-fashioned Names of 

 British Birds is a most excellent and useful compilation, which 

 should prevent many errors on the part of too hasty transcribers 

 of observations, and prove a boon to puzzled readers of local 

 notes. A List is given of the 376 Birds accepted as British by 

 the Committee of the British Ornithologists' Union in 1883, and 

 also of the " Terms applied to Wild Fowl," as, for example, 

 " Buff. ( a hill of,' several."
