of British Insects, comprising the best means of obtaining and preserving them, and 



a description of the apparatus generally used ; together with the genera of Linne, 



and The Modern Method of arranging the Classes Crustacea, Myriapoda, Spiders, 



Mites and Insects, from their Affinities and Structure, according to the views of 



Dr. Leach. Also an explanation of the terms used in entomology ; a calendar of 



the times of appearance and usual situations of near 3000 species of British insects ;

The preface explains that "The Modern System is nearly the same as that given in the 

 Supplement to the Encycloi^aedia Britannica, article Crustaoeology, and Dr. Brewster's 

 Edinburgh Eneyclopsedia, article Entomology, wiih the exception of the foreign Genera 

 and the alteration of Tribes to Families, terminating in idx." Notwithstanding this 

 notice, the three Families belonging to the Amphipoda are given, pp. 101-106, as " Fam. I. 

 Phrontmada Leach's MSS." "Fam. 11. GAMMARiDiE. Leach's MSS." "Fam. IIL 

 Caprellad^. Leach." AU the information is derived from the papers by Leach. The 

 articles referred to in the Preface are probably the Crustaceology of the Edinburgh Ency- 

 clopaedia and the Annulosa of the Supplement to the Encyclopsedia Britannica.

 by the marine insects or microscopically luminous shrimps (Krebsohen). Of these he
