Genus Laoma (Gray, 1840). [P. 733.] 



This genus, as utilized by Suter, is obviously polyphyletic. The type 

 is quite unlike the majority of the species associated with it. 1 have not 

 studied the species sufficiently to give a correct revised grouping. Phrix- 

 gnaihus should be generically utilized at once, whilst my investigation of 

 the Kermadec land molluscs forced me to introduce a new genus Paralaoma : 

 the Neozelanic Laoma lateumbilicata seems to fall into this. Suter's groups 

 in this genus under the subgenus Phrixgnathus are very artificial, being 

 based on the width of the umbilicus. I believe that study of the apical 

 features will aid in forming a natural grouping of this family also, and I 

 hope to provide such when I indicate the Endodontoid genera, as well as 

 the groups of the Flammulinidae, where I have also found the apical features 

 constant and valuable.
