PLEUROTOMA. 95 
British distribution—Chiefly in the Coralline zone on 
the southern and western coasts of Britain, and all round 
Ireland. Mr. Barlee has taken it in the Hebrides, and 
Professor Edward Forbes in the Firth of Forth. This latter 
is the only reliable instance which I have observed of its 
occurrence on our eastern coast. 
Foreign localities—The Atlantic coast from France to 
the Canaries, and throughout the Mediterranean and Aigean 
Seas. 
Pleurotoma rufa, Montagu. 
Murex rufus, Montagu; Fusus fuscus, Brown ; Mangelia 
(Bela) rufa, Forbes and Hanley. 
Habitat—Two small specimens, dead but apparently fresh, 
from Lamlash Bay are all that I have seen—they were 
obtained by my brother many years ago. Messrs. Greville 
and Miles dredged a single example from the same bay, 
from whence also Dr. Landsborough reports it. 
British distribution.—On nearly all our coasts from the 
Channel Islands to the Hebrides on the west, and Moray 
Firth on the east. 
Foreign localities—Norway (Sais), northern and western 
France (Macé, and others), “ Naples (Ziberi, and others),”

* Pleurotoma turricula, Montagu. 
Murex turricula, Montagu; Murex angulatus, Donovan ; 
Defrancia nobilis and D. sealaris, Méller ; Fusus turricola, 
Fleming; Mangelia (Bela) turricula, Forbes and Hunley. 
The variety rosea = Tritoneum roseum, Sas. 
Habitat—On hard ground—gravel and stones—from 8 to 
30 fathoms; rather common in most parts of our Firth. It 
is to be obtained specially fine and plentiful off Bogany, in 
Bute. The variety rosea occurs with the type. 
British distribution.—On all the English and Scotch 
coasts north of the Bristol Channel, and round the whole of 
Ireland, but probably most at home in the west of Scotland. 
Messrs. Leckenby and Marshall record it as very fine on the 
Dogger Bank. Mr. Jeffreys is not satisfied that it has been 
found on the southern coast of England, but it undoubtedly 
occurs on the opposite coast of France. 
Foreign localities—Northern France (De Gerville, and 
others), Norway (Loven, and others), Iceland (Verkriizen), 
Greenland (Mdéller), Labrador (Packard), St. Lawrence 
(Whiteaves), Massachusetts (Gould).
