 that of the British Isles. 



Adopting the same plan as in the previous two Reports 

 the localities where work has been carried on may be 

 enumerated as follows :— 



I. Puffin Island— chiefly shore hunting. 



II. Isle of Man, visited at Easter, when the electric

the Report by E.L.b. and E.L.s. for the bottom and sur- 

 face respectively. 



III. Colwyn Bay from the Little Orme (8 fath ) to 

 Penmaenrhos. The greater part of the species collected 

 here were obtained by using a small dredge with a frame 

 of sheet brass 12in. long by ^m. wide with a bag of 



cheese-cloth " open at the tail end but closed by a 

 wrapping of string. A small lead weight was attached to 

 the dredge cord about 3ft. in front of the dredge. After 

 dragging the dredge for a short time on sandy gi-omid it 

 would be brought up containing a considerable quantity of
