However, ha;d Lifter but added an in- 

 dex of the numerous feftions, parts, and 

 chapters, to his work^ his Shells would 

 he very cafily traced, though they feem 

 more confufedly placed than in any other 

 author. His arrangement, though not 

 good m the whole, is fo critically metho- 

 dical, that a perfon the lead convcrfant in 

 Conchology can in^mediately find if a 

 Shell is figured by him or not. For 

 example,- his chapters of the Cowries are 

 regulated as follows, viz. Cowries of one 

 colouro 2d. Streaked. 3. waved. 4. Simply 

 ringed or banded, and banded and fpotted; 

 t;. and 6. Tpotted or painted in a nett- 



w^ork."
