with no less than thirteen. Characters and descriptions are given 

 of the whole of the species, and references are made to the au- 

 thours by whom they have been described and figured, especially 

 to Rondeletius, whose faithful and spirited though sometimes 

 rude representations, are thus rendered available to modern sci- 

 ence. The local names are also given, the uses to which they are 

 applied are stated, and the modes employed for their capture and 

 preservation are particularized. In this section of the work every 

 thing is in fact attended to which could tend to make it complete. 

 It is illustrated by figures of forty-seven of the species described 

 in it. 



The Crustacea^ two hundred in number, are treated with the 

 same detail as the Fishes, and thirteen of them are figured in the 

 illustrative plates. They also had been the subjects of a former 

 work by M. Risso, which it is the object of his present Natural 

 History of them to reproduce in an improved form, with the addi- 

 tion of such species as have been since discovered by him. Ex- 

 tensive as was his former list, the additions here made to it are 

 numerous. In this department also there are a few new genera ; 

 but they are less frequent than in most of the other classes of 

 Inveriebrata, the authour having adopted the whole of those so 

 ably described by Dr. Leach. 



To Dr. Leach he is also evidently indebted for much assistance 

 in his species of the Myriapoda^ Scorpionidcs^ and Arachnida : 

 and he especially acknowledges the aid of our distinguished 

 countryman in his notice of the Insects captured in the district. 

 This latter extends to only about sixteen hundred species, and 

 exhibits merely a list of their names in Latin and French, except 

 where a very few new ones are characterised and described. Of 

 such there are only thirty-four, and among them are included the 

 thirteen species of Formica^ and three of Culex, described by Dr. 

 Leach at page 289 of our second volume. One new genus of 

 Orthoptera is proposed under the name of Phantoma : it is nearly 

 allied to Phasma. 



The list of Vermes embraces seventy-five species, ten of which 

 are stated to have been hitherto unnoticed. The Radlata, one 

 hundred in number, including those which are found only in the
