APPENDIX. 
I. SYNONYMS OF MOLLUSCA. 
In consequence of the great change that has taken place in the no- 
menclature of this class, the names used by Mr. Thompson are, in many 
cases, different from those of Forbes and Hanley, the latest authorities on 
the subject. It has therefore been considered desirable to enumerate all 
such species, giving in one column the name employed by Mr. Thomp- 
son, and opposite to it in another column, the corresponding term of 
Forbes and Hanley.
