Dillwyn. A Descriptive Catalogue of recent Shells, ar- 

 ranged according to the Linnean method, by Lewis Weston 

 Dillwyn, F.R.S. and F.L.S. in two vols. octavo, 1817- 



Of a forcible and comprehensive intellect, Mr. Dillwyn 

 has already given sufficient proofs. In his present work, 

 however, we cannot resist the suspicion, that he has yielded 

 much to conjecture, and formed his specific characters, 

 more in accommodation to his own opinions than strict pre- 

 cision will justify. 



Tellina Radula and Venus spuria are united, with the 

 specific characters of each combined together. Both the 

 species are before us. The former is dull brownish white, 

 with numerous rough rasp-like transverse ridges, without 

 the longitudinal groove or flexure on the anterior side, 

 where the margin runs in a straight direction from the 

 beaks ; the inside is slightly striate longitudinally, with two 

 primary teeth only in each valve. The latter is glossy- 

 white, with a few transverse wrinkles, and a longitudinal 

 groove down the anterior side, where the margin is rounded 

 from the beaks ; and the inside has no longitudinal striae, 

 with three primary teeth in each valve. The Solen vesper- 

 tinus of modern authors, is referred to the Tellina albida of 

 Linne, with the observation that it answers to the descrip- 

 tion in the Systema Naturae ; a correspondence which we 

 cannot exactly acknowledge. The T. albida is described as 

 smooth, and having three teeth in each valve. The Solen 

 vespertinus is transversely striate, and has a single tooth 

 in one valve and two in the other. Our Tellina tenuis, 

 which has a single cloven tooth in one valve, and two in 

 the other, with a minute lateral tooth in one valve only, is 

 referred to the T. balaustina of Linne, omitting to observe, 

 that this last is described as having lateral teeth in one 

 valve 5 valvuld altera dentibus lateralibus. His" Venus ri-
