MARINE BIOLOGICAL STATION AT PORT ERIN. 293 



GasterosteiDtE. — Gasterosteus spinachia (15 spined 

 Stickleback) is a littoral form ; distribution as for the last 



species. 



Labrid^e. — Labrus mixtus (Cook Wrasse) is abundant 

 round the breakwater, and was occasionally taken off 

 Bradda Head and in Bay Fine. 



Gadil\e. — A large number of young forms of various 

 species of Gadus are found around the breakwater. 



Gadus virens (Saithe) : young taken in the dredge within 

 the Bay. Gadus pollachius (Pollack) is abundant : taken 

 within the Bay near the buoy; also taken outside 

 frequently from north of Fleshwick to Halfway rock. 

 Gadus morrhua (Cod) and Gadus ceglefinus (Haddock) : 

 generally taken a few miles outside the Bay. 



Molva vulgar is (Ling) is taken to south of Port Erin 

 (Bay Fine and off the Calf). Merluccius vulgaris (Hake) : 

 distribution as for G. morrhua. Motella mustela and M. 

 tricirrata (Bocklings) are taken in the vicinity of the 

 breakwater. 



OphidiiDjE.— One species only, Ammodytes tobianus 

 (Lesser Sand Eel). This is taken at low tide in pools on 

 the south side of the Bay near the landing stage. 



Pleuronectltle. — I only succeeded in capturing two 

 species of flat fish — Pleuronectes platessa (Plaice) and P. 

 limanda (Dab). I should be inclined to think that other 

 Pleuronectids are common. Both species mentioned were 

 taken frequently in the Bay and outside the Bay from 

 the breakwater to Halfway rock. Young forms were 

 frequently taken in the dredge, both inside and outside 

 the Bay. On Aug. 21st, a shoal of young Pleuronectids 

 were observed at low water opposite the Laboratory. 



ScoMBRESOCiDiE. — Belone vulgaris (Garfish) is taken 

 when "whiffing" for mackerel. Probably accompanies 

 mackerel shoals.
