Habitat.— Tenby (Goodall) ; Falmouth (Cocks) ; Berwick Bay (Johnston) ; Shetland 

 (Daly ell). Large examples are found in the creek to the south of the jetty at Loch- 

 maddy, and at various parts of the Loch at extreme low water, under stones, and 

 especially where the bottom is composed of shell -gravel ; dredged in Fermain Bay, 

 Guernsey, attached to the interior of an old valve of Pecten ; not uncommon in old valves 

 of Lamellibranchs in the laminarian region (6 — 8 fathoms) in Bressay Sound, and more 

 frequently in 8—10 fathoms amongst horse-mussels in the West Voe of Scalloway. It is 

 abundant at Herm under stones near low water-mark, and dredged in various shells off 

 this island in 12—20 fathoms. Dredged off Peel, Isle of Man, 10—12 miles from shore
