THE CABINET OF SHELLS. e 
THIS THEORY, 
or Outline of the Testacea, does not admit of a full de- 
scription of shells or of their habitudes ; but it is a fact worthy 
of observation, that their variety and beauty attracted the at- 
tention of the earliest philosophers. 
THE SCIENTIFIC ARRANGEMENT 
OF SHEELES 
was completed by the immortal Charles Linnezus, M. D. who 
was born in Sweden, in the year 1707. ‘To this great natu- 
ralist we are indebted for the following simple and compre- 
hensive arrangement of the science. 
He has divided the 
CLASS: TE Sv AO hs a 
into three ORDERS, containing thirty-six GENERA. (See 
the plates.) 
Order 1st. Multivalve, or many shells. 
Order 2d. Bivalve, or two shells. 
Order 3d. Univalve, or one shell. 
In the order MULTIVALVE are three Genera : 
Genus 1. Chiton, or Coat of Mail. The animal a Doris. 
Of this Genus are 40 Species. 
Genus 2. Lepas, or Acorn shell, or Barnacle. The animal a Triton. 
Of this Genus are 43 Species. 
Genus 3. Pholas, or Stone-piercer. The animal an Ascidia. 
Of this Genus are 12 Species. 
In the order Multivalve are ninety-five Species, each having 
a separate name, as Chiton Squamosus, Chiton Bistriatus, 
&c.
