J>fiBd-fbI XXIX. — Some Account of a Dredging Expedition on the coast of the Isle of Man during the months of Mag, 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 during 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 ^glefinus, Cuv. Taken with the long . ilaes : is in best season in the winter and spring. The Cod, Morrhua vulgaris, Cuv. Taken in the same manner as the last. «. ^ilyii a; a^AtiX auia. ^vu\\>s "S^*>v-r> M'.'unac-
