USEFUL WORKS OF REFERENCE. 



The following list includes only such works as will aid the 

 student in arranging and identifying his collections, all mor- 

 phological papers being purposely omitted. The more useful 

 of these are printed in full face type. While the list is far 

 from perfect it is hoped that it will prove of use to the 

 zoologist. 



The majority of the titles have been translated either in 

 full or in abstract, but the language in which the article is 

 written is indicated by the abbreviation following the title. 

 For a more complete list of papers, students should refer to 

 the various special bibliographies quoted. The catalogues 

 published by Friedlander und Sohn of Perlin will also prove 

 useful. 



All Museums should possess Dictionaries of French, 



German, Latin, Swedish, Danish, Spanish, Italian, Portuguese
