2 PREFACE. 



dustry of Plymouth, prepared by Mr. Walter Heape at tlie 

 request of tlie Council of the Association, with the view of 

 furnishing to naturalists information concerning the food- 

 fishes taken off Plymouth and their mode of capture, 

 which is necessary as a preliminary to those " accurate 

 researches leading to an increase of our knowledge as 

 regards the food, life-conditions, and habits of British food- 

 fishes and molluscs," which the Association was founded to 

 promote. 



A list of the Fauna and Flora of Plymouth Sound, so far 

 as known at the present date, i. e. before the Association has 

 commenced its operations, will be published in the next 

 number of the Journal. It will be one of the objects of the 

 naturalists working at the Plymouth Laboratory to extend 

 this list, and to ascertain the relations to one another and 

 to physical conditions of the various organisms therein 

 included, especially of those which are either themselves 

 commercial fishes or serve as the food of such fishes. 



Communications intended for the Journal should be 

 addressed to the undersigned.
