It is recommended to the young student in Con- 

 chology to compare carefully, the following Spe- 

 cific Descriptions with the Plates to which they re- 

 fer, at the same time turning to the Nomenclature 

 for the exact signification of the terms. By re- 

 peating this exercise till the species adopted as 

 examples of the different genera and sections be 

 perfectly known, a solid foundation will be laid for 

 a more extensive acquaintance with the numerous 

 beautiful and interesting individuals which are all 

 to be arranged under some one or other of these 

 generic forms. Those who may wish to acquire 

 an accurate knowledge of the Linnaean system 

 with still greater certainty, will find much benefit 

 in selecting for examination a good specimen of 

 each shell here illustrated, and placing them in a 

 cabinet in their proper order. A regular series 

 upon this plan, consisting of more or less valuable 

 shells, with references to the annexed drawings, 

 may be procured from Mrs. Mawe, 149 Strand, in 

 whose superb collection almost every instructive 

 subject may be viewed, and from whose liberality 

 and science much information will be derived.
