CORRECTION OF AN ERROR IN MR. WETHERELL's PAPER, AND 



NOTICE OF Venus Motrisii, a new fossil shell, by j. de 



C SOWERBY, ESQ., F.L.S. 



The following is a correction of an error in the list of fossil shells 

 given in Mr. Wetherell's observations on sonie fossils of the London 

 clay, published in the London and Edinb. Phil. Mag., vol. ix. page 

 464. (No. 56, for Dec. 1836.) 



Among the Conchifera yenns incrassata is mentioned as occurring 

 in the Hampstead Well andatBrackenhurst; this is an error: the shell 

 found at these places and at Heme Bay, and several other places in 

 Kent, proves, upon careful comparison with the V. incrassata of 

 Mineral Conchology, to be quite distinct j it has a much more slen- 

 der hinge, and is wider in proportion to its length. Having been 

 indebted to Mr, Morris for this discovery, which is important be- 

 cause the true V. incrassata belongs to the upper marine formation, 

 it is desirable to commemorate the fact by naming the new shell 

 Venus Morrisii. I have taken upon me to correct this error be- 

 cause it originated with me. J. De C. Sowerby.
