PAL-aEOSTTOLOGY. 



4. INDEX OF NEW SPECIES. 



Owing to the fact that palaeontological memoirs may contain descriptions 

 of animals belonging to different zoological groups, no zoological arrangement of 

 papers can be adopted, save at the expense of great repetition. To meet this 

 difficulty the following analytical index has been made, in the hope that it will 

 serve as a key to the abstracts. 



The genera and species are arranged in alphabetical order under their zoolo- 

 gical groups. A worker, therefore, in any branch of Palaeontology is enabled to 

 refer to the papers in which he is interested, and to form a notion of the dis- 

 coveries of the year in that branch. 



Names of new genera or subgenera are marked with an asterisk. The numbers 

 are those of the pages, where a reference to the species will be found ; " Add." and 

 " Suppl." respectively refer to Addenda and Supplement for 1874.
