INTRODUCTION. 



The collection of Sea Anemones with which the present paper is concerned 

 has been made by tin- Fisheries Branch of the Department of Agriculture 

 and Technical Instruction, Ireland, between the years 1S99 and 1913. 

 Mr. C. L Walton Bi.Sc., of thia College, consented at first to identify the 

 contained specimens; but the collection is a very large one, and Mr. Walton 

 was unable to give to it the necessary time, on account of circumstances which 



sequently arose. Be therefore handed the specimens over to me, and for 

 gome time 1 have given them my attention. 



The notes which follow do not deal with more than half the collection at 

 most : but as 1 shall be unable to deal with the remainder for some time, I 

 am publishing the results bo far. I Bhould like t" say that the descriptions 

 which follow are not intended to present an exhaustive study of the species 

 with which they deal - circumstance? have not permitted that; but I hope 

 they will be found to give what is essential for identification and general 

 purposes. My original intention was merely to identify the Anemones; but 



era] of them proved to be new species, and some of them to lie so interest- 

 ing, that it seemed a pity not to publish .some account of them. The micro- 

 scopical part of the work is based for the most part rather on a limited 

 number of selected sections than upon large series, as I have found the latter 

 to be unnecessary for the present purpose. In staining sections of Actiniaria 

 I find the Haematoxylin-Eosin method (see 48,' p. 2) the most generally
