THE SYSTEMATIC Vist 
The systematic list of algae has been compiled during 
the past ten years by periodic collection from five points 
in the south-west corner of the Island, namely :—Port 
Erin, Port St. Mary, Fleshwick, Castletown gana 
Pooyllvaaish. The nomenclature and system of classifica- 
tion here adopted is that established by Batters (1902) 
in his ‘‘ Catalogue of the British Marine Algae,’ but where 
the author of the catalogue has made alteration in a name 
long familiar to algologists, the older name is introduced 
in brackets. In certain instances Batters’ naming of 
a species has been revised by Mr. A. D. Cotton (1912) in 
his report on marine algae in the Clare Island Survey. 
The revised names have been adopted here. 
The present list is in part an amplification of several 
previous lists, to which has been added a considerable body 
of new data accumulated during the past few years by 
various workers who have visited the station from time to 
time, and by the authors themselves who have collected 
regularly throughout several years over the five collecting 
grounds. 
The only comparatively recent list of the algae of the 
Island is one compiled by MHarvey-Gibson, Knight 
and Coburn (1913) and published in the ‘‘ Transactions 
of the Liverpool Biological Society.’ The list in question 
includes the names of all algae found by the authors 
themselves or occurring in the scientific papers of previous 
collectors (Bradley, 1861; Garner, 1867; Gatty, 1872 ; 
King, 1889; Marrat, 1863-4; Talbot, 1890). Where 
species have been recorded but not seen by the authors 
the authority for the record is given in brackets. The 
present authors have adopted the same policy. | 
Since the publication of the r913 list the recorded
