INDEX TO PLATES. 27 



PLATE XI a. 



HELIX BUCCULENTA Gould. 



By some unfortunate arrangement of the copy, the de- 

 scription of this species was wholly omitted in the text. It 

 is incidentally alluded to on pages 91 and 109. The omis- 

 sion may be partly remedied by the insertion of the descrip- 

 tion here. See page 9. 



PLATE XII. 

 HELIX DENTIFERA Binney, p. 134. 



PLATE XIII. 



HELIX APPRESSA Say, p. 140. 



PLATE XIII a. 



HELIX DIVESTA Gould. This species appears in the 

 text, under the name of H. abjecta, which name had been 

 previously employed by Lowe (Fauna Maderensis) for a 

 Madeira shell. The above name is therefore substituted. 

 On page 135, at the bottom, for abjecta read divesta. p. 122.
