OF THE BAYS BETWEEN THE START AND EXMOUTH. 545 



LIMPET EOCKS OFF TORCROSS. 



A haul of the dredge was taken on this ground. Of the fifty-seven 

 species recorded, twenty-six, all mollusca, were represented by dead 

 shells only. Corhula nucleus, Solen pellucidus, Syndosmya alha, and 

 Niicula nitida were each represented by two living specimens, these 

 being the only living specimens of those species which we obtained. 

 Shells of Mactra stultonim were common, although it was not found 

 alive, nor in the stomachs of any fish captured in the bays. It was 

 found, however, in spawning Plaice caught in the deep water off 

 Portland. Of the other species recorded only few specimens were taken. 



Soil, coarse sand and rocks.
