284 On a Dredging Expedition on the coast of the Isle of Man. 



Salmon Trout, Salmo Trutta. Taken in the same manner as 

 the last species. 



Herring, Clupea Harengus, Linn. The Isle of Man is cele- 

 brated for its herrings, which appear generally on the Peele side 

 of the island in June ; towards August they are chiefly found on 

 the Douglas side, but are not considered such good-eating then 

 as they are when taken on the Peele side. A very large number 

 of fishing smacks, or luggers, as they are called on the island, are 

 employed in the herring trade ; I have counted upwards of ninety 

 within sight at one time from the Calf; there are also several 

 carrying-boats employed to take the herrings off for sale to 

 Liverpool and elsewhere. 



Skate, Kaia Batis, Linn. Common. 



Sand Ray, Raia maculata, Mont. Not uncommon, but not 

 so frequent as the last. 



Worm Pipe-fish, Syngnathus luhriciformis, Jen. One speci- 

 men taken under stones in Douglas Bay.
