WOOD-CUTS. 



THE originals of the wood-cuts representing the lingual hooks, were unfor- 

 tunately mislaid by the engraver ; so that the respective species to which 

 they belonged could not be identified. Many of them were, therefore, intro- 

 duced at random. Some of the drawings having been subsequently foundj 

 the following have been determined : 



Page 44, Helicina orbiculata. 



" 102, Helix albolabris. 



" 131, Helix thyroidus. 



" 139, Tebennophorus Caroliniensis.

NOTE. The name H. dejecta, (pp. 47, 89,) having been previously 

 appropriated, and also H. abjecta, (pp. 122, 135,) which refers to the same 

 shell, the name H. divesta is to be substituted.
