British distribution.—Nearly everywhere on hard ground, 
from the Channel Islands to Shetland. 
Foreign localities.—Iceland (Steenstrup), Norway (Lovén, 
and others), Spain, Portugal, Madeira, and Canaries

FAmMILy PLEUROTOMATIDE, Lovén. 
DEFRANCIA, Millet. 
Defrancia teres, Yorbes. 
Pleurotoma teres, Forbes; Pleurotoma boreale, Lovén ; Man- 
gelia teres, Forbes and Hanley. 
Habitat.—Outside the Tan Spit, and on a rough banx oft 
Shellbole Bay, Cumbrae; only three or four specimens, all 
dead. Mr. Norman took a single specimen alive in Lamlash 
Bay, where Drs. Greville and Bryce are also said to have 
taken it. Mr. Barlee records this species from Loch Fyne. 
British distribution.—Scarce throughout our seas. Mr. 
Jeffreys quotes the following localities—Cornwall, Plymouth, 
Northumberland, Durham, Berwick Bay, Shetland, Orkney, 
west of Scotland, Antrim, Connemara, and west of Ireland. 
Foreign localities—Norway and Sweden (Lovén, and 
others), Spain, Madeira, and Canaries (‘A ndrew), the Medi-

Pleurotoma gracilis, Fleming; Mangelia gracilis, Forbes 
and Hanley; Pleurotoma vulpecula (of Brocchi), Lamarck, 
ed. Desh. 
Habitat—On hard ground from 10 to 25 fathoms; a rather 
scarce shell. I have taken fine specimens on Bogany Point, 
and on the Craigmore shore, in Bute; off the Little Cumbrae, 
south of the Castle; and on the rough bouldery bank off 
Shellbole Bay, Cumbrae. My finest specimens measure 115" 
in length. Mr. Norman does not seem to have taken this 
species, but M‘Andrew and Landsborough record it from the 
Clyde district. 
British distribution —From Guernsey to Shetland ; com- 
mon in the south, becoming scarcer on the western and
