SUPPLE MENTAEY EEPOET upon the HYDKOID 

 ZOOPHYTES of the L.M.B.C. DISTKICT. 



By Miss Laura Roscoe Thorni«:ly. 

 With Plate IX. 



[Read February 9th, 1894.] 



Editorial Note. 

 The first vohime of the Fauna of Liverpool Bay, published 

 in 1886, contained a report upon the Hydroida, drawn up 

 by Mr. W. R. Melly, Dr. Sibley Hicks and myself, in which 

 were recorded 63 species. Since then a certain amount 

 of work upon the Zooph^^tes of the district has been done 

 by Mr. W. J. Halls and by Mr. O. W. "Wood, and the 

 additions to our list made by these gentlemen, and by Miss 

 Thornely, have been noted from time to time in the annual 

 reports. But by far the greater part of the work in this 

 group since 1886 has been done by Miss L. R. Thornely 

 who has worked carefully through all the mass of material 

 brought home by the various dredging and other collecting 

 expeditions and has identified and mounted the species 

 new and old. Miss Thornely's work has been carried on 

 to some extent in the Zoological Laboratory of the 

 College, where she has arranged the Hydroida and the 

 Polyzoa in the "Local Collection"; and she has also stud- 

 ied the living material at the Port Erin Biological Station. 

 The success of her w^ork will be seen from the numerous 

 entries in the carefully compiled table of geographical 

 distribution in the district w^hich follow- s, from the fact that 

 the total number of species has been raised from 63 in 1886 

 to 87 in 1893, and from the accompanying plate (PI. IX.)
