280 Bihliographical Notices, 



most natural illustrations of a Cephalopod that we have seen ; and 

 at the end of the volume are eight plates illustrating the genera de- 

 scrihed here, and of similar character to the plates of the preceding 

 volumes. But besides these, there are one hundred and two ' Suj)- 

 2)le77ient(d Plates,' containing figures of all the species of shells 

 (and of some of the more marked varieties) described in the entire 

 ■work, which is thus completely illustrated. These plates supply 

 what was felt to be greatly needed in the earlier volumes, and Mr. 

 Jeffreys's work must now become the standard authority on the 

 MoUusca of the nortli of Europe. The figures, upon the whole, 

 are good, certainly better than could ha7c reasonably been expected 

 for the small sum at which the volume is procurable ; but we could 

 have wished that Mr. Sowerby had bestowed more care upon some 

 of the closely allied and less easily discriminated smaller shells, and 

 especially that the plan of giving a single whorl more highly mag- 

 nified had been more extensively carried out. The experienced con- 

 chologist will be glad to find in these plates illustrations of the 

 recent additions to the British fauna in engravings of seventy-eight 

 shells which are not to be found in the older authority, Forbes and 

 Hanley. 



Below we give, as in the previous notices, a concise summary of 

 the MoUusca introduced to us in vol. v. which arc recent acqui- 

 sitions to the fauna of our islands : — 



ApJysia depilans, Linne. Guernsey (Gallienne). 



Eolis ccendea, Montagu. Weymouth (Thoni2)son) ; Salcombe Bay 

 (Hincks). 



E. Adelaidce, Thompson. Weymouth {Thompson) (=E. Roher- 

 tiancc, M'Intosh, St. Andrews). 



Doto cuspidata, A. & H. Slictland {Jeffreys Sf Waller). 



Hero formosa, Lovc'n. Northumberland {G. S. Brady); Firth of 

 Clyde {D. Robertson) ; Minch, off Loch Carron {J. G. J.). 



Lomonotus Portlandieus, Thompson. Weymouth Bay {Thompson). 



Crimora capillata, A. & H. Guernsey {Norman).

Rossia papillifera, Jeffreys. North of Shetland, 60-100 fathoms 

 {J. G. J.). 



In the Supplement we find the following, cither now first added 

 to the British fauna, or forms wliich had been regarded as varieties 

 in the body of the work, but arc here reinstated as of specific rank. 

 The latter we have indicated by brackets, to distinguish them from 

 the true novelties : —
