FUETHEE EEPOET upon the FEEE-SWIMMING 



COPEPODA of the WEST COAST 



OF IEELAND.

[Read May 14th, 1897.] 



The former Eeport (Trans. Biol. Soc, L'pool, Vol. X., 

 p. 92) dealt with a collection of plankton, the result of a 

 series of tow-nettings made by my friend Mr. Edward T. 

 Browne, B.A., of London, off Valencia on the West of 

 Ireland during the summer and autumn of 1895. 



Mr. Browne again made Valencia his head-quarters 

 in July 1896, remaining there until near the end of 

 September, using the tow-net on most suitable days 

 either inside or outside of the harbour. The results are 

 contained in 41 bottles, numbered 1 to 41 in accompanying 

 tabular resume, the total number of species found being 29. 

 During part of the time Mr. Browne had as companions 

 Mr. A. 0. Walker, F.L.S. , of Colwyn Bay, and Mr. F. 

 W. Gamble, of Owens College, Manchester. Both of 

 these gentlemen have kindly sent me material they 

 collected by tow-net. The conditions under which the 

 latter were obtained being similar to those of Mr. Browne, 

 they are included in the tabulated results, having no 

 specially distinctive features. Through the kindness of 

 the Misses Delap, daughters of the Vicar of Valencia, 

 themselves trained naturalists, the work of tow-netting 

 was continued throughout the autumn and winter up 

 to March 1897, the bottles numbered 22 to 41 being 

 contributed by them. 



The previous Eeport had to do chiefly with tow-nettings 

 taken during the months — April, May and June 1895,
