The localities given may be relied on as correct, all report to the 

 contrary notwithstanding. Such as are doubtful are so marked. A 

 few of the species occur on more than one island ; of such I have 

 given what I suppose to be the original locality, or the one which 

 may be regarded as the metropolis of the species at present. 



the generic position of a few species of Helices is not determined ; 

 they have been arranged provisionally under the genus Helix. Spe- 

 cies of aberrant form are classed under the genera to which they are 

 the nearest related, separated by asterisks.
