The Genera of Recent and Fossil Shells, for the use of Students 

 in Conchology atid Geology. By G* B. Sowerby, F.L.S. 

 With original Plates^ by J. D. C. Sowerby, F. L. S. 

 No. xxvii. 



In this number, as in the preceding ones, five genera are illus- 

 trated. 1. Siliquaria ; an interesting genus of Annelida, sepa- 

 rated from the Linnaean Serpulce by Bruguiere ; the very splen- 

 did specimen of the S. anguina, which formed part of the Tanker- 

 ville collection, being the prominent figure in the accompanying 

 plate. 2. Octomeris ; a new genus oi Cirripeda described by Mr. 

 Sowerby, at page 244 of our present volume. 3. Pinna; illus- 

 trated by the P. serrata, and the P. nigrina, forming two plates. 

 4. Mytilas ; the species figured being the M. achatinus; M. crena" 

 tus; and the M. polymorphus, a native of the Danube, which has 

 recently been naturalized in the Commercial Docks, near Lon- 

 don. 5. Modiola, illustrated in two plates, which exhibit the 

 M. picta, M. Silicula ?, M. Tulipa, M. semifusca, M. plicata^ 

 M. discrepans, and M. discors. The two latter species, which 

 are natives of the British coasts, difiier much, as Mr. Sowerby ob- 

 serves, from the conimon Modiolce, and might, perhaps, with pro- 

 priety be considered, together with some others, that resemble 

 them in form, as constituting a distinct genus.
