THE MARINE ALGAE OF THE L.M.B.C. DISTRICT. 125 



in 1889. 7 The identifications recorded in these papers 

 were incorporated in the Revised Report . Short lists 

 are also furnished by Mrs. Gatty 8 and Mr. Garner. 9 



The present paper deals with observations made by 

 us at Port Erin, Port St. Mary, Fleshwick Bay, in April, 

 1911, and April, 1912, and by two of us (M. K. and H. C.) 

 at Peel in July and August, 1911, and August, 1912. 



We have omitted from our present list all reference 

 to the so-called Cyanophyceae, partly on account of the 

 difficulties of identification which such forms present, 

 but chiefly because it is now becoming customary to 

 exclude this group entirely from Algae, in the strict 

 sense of the term, and to associate them with the Bacteria 

 as Schizophyta. The Diatomaceae will also receive 

 special treatment at the hands of Miss E. M. 

 Blackwell, M.Sc. 



Species which have been collected by one or other 

 of us are indicated by the locality only ; other species 

 recorded, but not seen by us, have appended to them, in 

 addition to the locality, also the collector's name, when 

 known. Species which, so far as we are aware, have 

 not been previously recorded from the Isle of Man, are 

 distinguished by an asterisk.
