PEEFACE. 



The want of a Catalogue of British Fossil Crustacea, in which all the 

 s3-nonyms should be given, has long been felt. 



The present task was commenced some years since ; but, owing to the 

 unsatisfactory state of one group, the Bivalved Entomostraca, which 

 greatly needed revision, the work was for some time laid aside for other 

 and more pressing occupations. 



Mr. Woodward completed this Catalogue on 22nd December, 1876 ; 

 and it is but fair to him to state that he could only devote a small 

 portion of liis official time to this work, having to attend to the 

 ordinary business connected with the Department, and also to catalogue 

 the largo accessions to the Fossil Invertebrata. 



Some idea may be formed of the progress of palseontological work 

 in this country from the fact that when Prof. Morris's Catalogue of 

 British Fossils was published in 1854, he recorded only 81 genera and 

 30G species of Fossil Crustacea. 



The present Catalogue contains a record of 107 genera, and lUol 

 species and varieties found fossil in Britain ; so that, since 1854, IIG 

 now genera, and 745 new species and varieties of Fossil Crustacea have 

 been figured and described in Britain.
