having now become seven in number (see Trans. L'pool 

 Biol. Soc, vol. V., 1890-91). 



Early in September, three lady students of University 

 College, Liverpool, Miss L. E. Thornely, Miss J. H. 

 Willmer, and Miss M. Beaumont, accompanied by Mr. 

 W. Thornely, spent a week at the Station chiefly in collect- 

 ing and preserving material and in examining the Hydroids 

 and the Polyzoa, at which Miss Thornely and Miss 

 Willmer had been working for some time previously. 



Miss Thornely has examined and identified nearly all 

 the collections of Hydroid Zoophytes and Polyzoa made 

 in the various expeditions during the year, and reports to 

 me that we have now found 71 species of Hydroids in the 

 L.M.B.C. district, and of these 34 have been found on the 

 shores of Puffin Island. Among the rarer forms found 

 recently may be mentioned : Hydranthea margarica, Sertn- 

 larella tenella, Campanidaria hlncksii, Gonothyrcea gracilis, 

 Aglaophenia tuhulifera, and Plumularia echinulata. During 

 her work at Puffin Island Miss Thornely found 

 the following four species of Polyzoa which had not been 

 previously recorded, viz., Lepralia pallasiana, Cellepora 

 avicidaris, Pedicelllna cernua, and P. gracilis. Miss 

 Thornely has also identified 25 species of Polyzoa found 

 by Mr. F. Archer at Bull Bay. 



In April, Dr. Hanitsch, Mr. Hornell, and Mr. C. H. IE. 

 Walker spent some time in collecting at Port Erin, Isle of 

 Man, where they succeeded in getting some remarkably 

 fine specimens of Pachymatlsma johnstoni and other species 

 of sponges, including two new to the district, viz., Reniera 

 ingalli, B., and Chalina montagui, J., the latter an extremely 

 fine specimen, equal to if not surpassing in size any speci- 

 men of the species ever recorded. In fact Dr. Hanitsch 

 considers that in sponges this year has been remarkable 

 rather for the number of fine specimens obtained than for
