XXIX. — Some Account of a Dredging Expedition on the coast 

 of the Isle of Man during the months of Maij, June, July and 

 August 1852. By T. C. Eyton, Esq., F.L.S., F.Z.S. 



Having been staying at Douglas, Isle of Man, for a period 

 of nearly four months during the past summer, and having a 

 small yacht, I have been out dredging, chiefly from off Douglas 

 Head to Maughold Head, weather permitting, pretty constantly 

 dui'ing that period ; it may not therefore be uninteresting to the 

 readers of this Magazine to know what the products have been, 

 more especially to those who may follow me over the same 

 ground. Professor Forbes has investigated the fauna of the 

 sea off the island, but his labours have been confined chiefly to 

 the S.W. coast, while mine, on the contrary, have been on the 

 N.E. side of the island. The beds I have been working upon 

 extend nearly continuously from about a mile and a half off 

 Douglas Head to Maughold Head ; the depth varies from 16 to 

 27 fathoms. The greatest portion of the bottom is covered with 

 Nullipore ; on some portions scarcely a live shell is found ; other 

 parts, especially off Douglas Head, Laxey Point and Maughold 

 Head, abound in scallops and oysters; the former are chiefly 

 dredged by the fishermen to set the deep sea line with, and fur- 

 nish an excellent bait for many kinds of fish, especially haddock. 

 The fishermen generally bait their lines with the scallops ob- 

 tained the first haul, while the dredge is down for another, 

 throwing the shells overboard, which will account to a certain 

 extent for the large number of dead shells on the beds. The 

 following is a list of the fish I observed while on the island : — 



The Haddock, Morrhua Mglefinus, Cuv. Taken with the long 

 lines : is in best season in the winter and spring. 



The Cod, Morrhua vulgaris, Cuv. Taken in the same manner 

 as the last.
