INTRODUCTION. 



This report, which is based on the collection made by the 

 Harriman Alaska Expedition, includes a systematic account of 

 the Anemones collected. It also includes a description of a 

 new Halcampid, Harenactis attemiata, from California, a dis- 

 cussion of the variation in Metridmm dtantkus, a few facts 

 concerning Epactis -prolifcra^ Verrill, and figures, from photo- 

 graphs, of several previously described species. In the Alaskan 

 collection six genera and six species are represented of which 

 one genus, Charisea, and two species, Charisea saxicola and 

 Ep'actis ritteri are regarded as new to science and are here 

 first described.
