It is recommended to the young student in Con- 
chology, to compare carefully the following Spe- 
cific Descriptions with the Plates to which they 
refer, at the same time turning to the Nomencla- 
ture for the exact signification of the terms. By 
repeating 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 Linneean 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 pro- 
cured 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.
