In this article Dr. Hagen has described shortly, and given a 

 few notes on, all the species of British Dragonflies, and, in addi- 

 tion, has similarly treated the European species most likely to 

 be found in this country. The list is nearly the same as that at 

 present received ; but six doubtful species, or extremely casual 

 ones are included. The nomenclature also does not greatly 

 differ from that at present recognised. The British species are
