XLl.— The Fauna of TwizelL By P. J. Selby, Esq., 

 F.R.S.E., F.L.S., &c. &c. 



[Continued from the ' Magazine of Zoology and Botany,' vol. ii. p. 387.] 



In the ^ Magazine of Zoology and Botany^ the attention of 

 naturalists was directed to the advantage that the zoology of 

 our own islands could scarcely fail to derive from local Faunas, 

 provided they were undertaken and conducted with accuracy 

 and care ; and an attempt was made to point out the precau- 

 tions necessary to be observed in order to render such Faunas 

 of the greatest possible utility to science. Upon a plan of the 

 kind proposed, the investigation of a small district was under- 

 taken by the writer, and lists of the animals, birds, reptiles 

 and fishes* were given in a second communication in the same 

 work, with a few observations upon the oeconomy of such spe- 

 cies as seemed to require additional notice. As a continuation 

 of this Fauna may not be altogether useless or devoid of inter- 

 est to some of the readers of the ^ Annals of Natural History,^ 

 it is proposed to continue it at intervals so as to embrace the 

 various divisions of the invertebrate animals. 



In the present communication catalogues of the coleopterous 

 and lepidopterous insects already found within the precincts 

 of the district subjected to investigation are given; and, as these 

 two divisions have been assiduously attended to for the last 

 three years, it is expected that they contain a great majority 

 of the species inhabiting the district, at the same time the 

 writer is aware that many must have escaped his notice and 

 search, particularly those of minute size, belonging to the Ni~ 

 tidulidce, Anisotomidce, &c., as well as those of rare occurrence 

 in the groups of the Pselaphid(B, Tachyporidce, Btenidce, &c. 

 The catalogue of the coleoptera, so far as they have been veri- 



* In the list of fishes the eels were omitted ; we have the two species 

 Anguilla acutirostris and latirostris.
