366 Miscellaneous. 



Elytra of a brilliant golden green, as wide as the thorax in front, and slightly 

 attenuated at the apex, where each is rounded and the edge furnished 

 with minute denticulations. 



I have dedicated this species to the Rev. W. Little, as a small 

 testimonial of the extensive services he has rendered to British En- 

 tomology in exploring its productions in the northern parts of the 

 island. 



Mr. Stephens, upon the faith of a casual glimpse of this insect, 

 says in the Appendix to his ' Manual,' that this species greatly re- 

 sembles the A. mendax of Dejeari, described by Mannerheim, ' Bullet, 

 des Natural, de Moscou,' 1837, No. viii. p. Ill ; by a comparison of 

 the two descriptions, it will however be found that two insects, in 

 the same genus, could not well differ more, their only points of re- 

 semblance being the small carinse at the base of the thorax. The 

 A. mendax is also one and a half line longer, a great difference in 

 small insects. 



ON MR. gray's edition OF TURTOn's MANUAL. 



Notice respecting the new edition of ' Turton's Manual of the Land- 

 and Fresh-water Shells of the British Islands, thoroughly revised 

 and much enlarged, by John Edward Gray, Esq., F.R.S. 8fC.' By 

 the Rev. William Hincks, F.L.S. 



Though far from being all that might be desired. Dr. Turton's 

 Manual has been found a convenient and useful book by those inter- 

 ested in the study of the British land and fresh-water molluscous 

 animals ; and though some may wish that Mr. Gray had rather been 

 induced to publish an original work on the subject, his improvements 

 in this edition give it a greatly increased value, and will be grate- 

 fully received by the lovers of this pleasing and generally accessible 

 branch of Natural History. 



But there is one part of Mr. Gray's plan, which he deserves our 

 thanks for introducing at all, which he was obliged to execute, as he 

 himself informs us, from such very imperfect materials, that the 

 benefit we derive from what he has attempted will consist rather in 

 the quantity of information that he will cause to be collected, than 

 in any great reliance that can be placed on what he has now given. 

 I refer to that part of his introduction which relates to the geo- 

 graphical distribution of the land and fresh- water mollusca in Great 

 Britain. His materials are no doubt good as proofs of the presence 

 of certain species in certain districts, but they are too imperfect to 

 allow of any safe negative conclusions. 



From no disposition to depreciate his admirable work, but for the 

 assistance of those who use it, I here note down a few facts which 

 have fallen under my own notice in contradiction to his statements.
