From a depth of fourteen fathoms, in the Sound between 

 Puffin Island and Penmon, Anglesea, the dredge was brought 

 up several times during the cruise of the " Hyaena," com- 

 pletely filled with specimens of this species. It was also 

 obtained opposite Bangor, on May 24th. During August, it 

 was found to occur in great numbers off Spanish Head and 

 Port St. Mary, Isle of Man, at depths varying from ten to 

 twenty fathoms ; bottom chiefly Nullipore and gravel ; and at 

 low-water mark in Douglas Bay. It was also found at Pen- 

 maenmawr, in July. Byerley {loc, cit,) records it as occur- 

 ring plentifully at Hilbre Island. We have found it in large 

 numbers under stones and among the roots of Laminaria at 

 low water spring-tides at Beaumaris, and in deep water at 

 several points between that town and Puffin Island.
