The examination of material from one highly prolific dredging off 

 the south coast of Cornwall, and littoral gatherings from ten locali- 

 ties between the Land's End and Plymouth, has proved to be a 

 task of remarkable interest owing to the richness of the marine 

 protozoan fauna, both as regards its abundance and development, 

 and the result of our examinations has been a list of 221 species 

 and varieties for the area under consideration. This list is ex- 

 panded to 256 by the addition of thirty-five species recorded in 

 the papers of Millett, Worth and Eobertson, to which reference is 

 made below, and which we have added in order that this present 

 paper may be regarded as complete up to the time of writing. 



The major portion of the ground may be said to have been 

 practically untouched hitherto. The late F. W. Millett published 

 in 1885* a list of 108 species and varieties, but his paper, as the 

 Introduction shows, was in the nature of a popular article, and no 

 authors of species, frequencies or diagnostic observations were
