This species was first described as British by Mr. Smith 

 of Jordanhill, who dredged it off Arran. It has been since 

 taken in numerous localities in the Hebrides and Zetlands, 

 in various depths from five to fifty fathoms ; the finest 

 specimens usually from the laminarian zone, and among the 

 stems of Laminarifz (M'Andrew and E. F.). In fifteen 

 fathoms, Eda Sound, Orkneys (Thomas). It has been 

 taken in Ireland (Thompson) ; on the Gal way coasts 

 (Barlee) ; and Cork (Humphreys). Guernsey (Metcalfe). 

 On the east coast of England it has been taken at Whit- 

 burn by the Rev. G. 0. Abbes (Alder). It ranges along 

 the coasts of Spain into and through the Mediterranean. 

 A specimen dredged off Gibraltar by Mr. M'Andrew, is 

 identical with the usual British form.
