NOTICE. 
‘Tue following lists have been prepared in conformity with the desire of the Committee of the 
Natural History Section of the British Association for the Advancement of Science, who, at my 
suggestion, recommended the appointment of a general Dredging Committee, with a liberal grant of 
money for the carrying out of its objects. 
It is intended to place these lists in the hands of the local Dredging Committees and naturalists 
engaged in researches in the most important districts of the coasts of Great Britain and Ireland, 
with a request that they may be returned, with notes on the conditions under which each species of 
the particular district has been found, and memoranda of such additional species as may be obtained. 
By this means it is hoped to collect local lists of great interest, and materials for a more complete 
catalogue of the Invertebrate Fauna of the British Seas. In the preparation of the present lists, I 
have been assisted by Dr. Baird and Mr. 8S. Woodward, and other members of the Dredging Com- 
mittee. The catalogue of Mollusca is taken from the work of Messrs. Forbes and Hanley; that of 
Crustacea has been obligingly furnished by Mr. Spence Bate; of Radiata by Mr. Stewart, of the 
Royal College of Surgeons ; of Sponges by Dr. Bowerbank ; of Rhizopoda by Messrs. Rupert Jones 
and Parker; and to Dr. J. E. Gray I am indebted for permission to extract the list of Anellides 
from an unpublished work by the late Dr. Johnston, of Berwick-upon-Tweed.
