LAMELLARIA, VELUTINA. 83 
FamILy VELUTINIDA, Gray. 
LAMELLARIA, Montagu. 
Lamellaria perspicua, Linné. 
Helix perspicua, Linné; Bulla haliotoidea (female) and 
Lamellaria tentaculata (male), Montagu. 
Habitat—In the Laminarian and Coralline zones off Far- 
land Point and the Tan Spit, Cumbrae ; and off Silvercraigs, 
Loch Fyne. Mr. Norman has taken it in a rock pool at 
the Allans Rocks, Cumbrae: and Mr. Hennedy, at Gourock, 
beneath stones. 
British distribution —Generally dispersed throughout our 
seas ; it finds a place in almost every catalogue. Besides the 
above genera this species has been referred to the genus 
Sigaretus (Cuvier) by Fleming, Brown, Philippi, and others ; 
to Coriocella (De Blainville) by Johnston, Kiister, and others. 
It is the Marsenia of Leach, Cryptocella of Adams, and Ermeea 
of J. E. Gray. 
Foreign localities—Norway (Lovéi), Spain, Portugal, the 
Canaries, and Madeira (M‘Andrew), Mediterranean and 
Aigean (Forbes, and others), Labrador (Packard), Massa- 
chusetts (Gould). 
VELUTINA, Fleming. 
Velutina plicatilis, Miiller. 
Bulla plicatilis, Miller ; Bulla flexilis, Montagu ; Sigaretus 
flexilis, Brown ; Coriocella flexilis, Macgillivray; Velutina 
flexilis, Forbes and Hanley. 
Habitat—I took a single live specimen on Bogany Point, 
Bute, near the buoy, on stony ground in about 12 or 15 
fathoms. Forbes and M‘Andrew obtained one specimen in 
Loch Fyne, on stony ground in 25 fathoms. This is probably 
one of our rarest shells. 
British distribution—Rare and local. It is recorded 
from Dunbar (Laskey), Whitburn and Cullercoats (Alder, 
and others), Dunnet Bay (Peach), Stromness Bay, Orkney 
(Forbes and Goodsir), and Tresta Voe, Shetland (Jeffreys). 
Foreign localities—Norway (Lovén, and others), Iceland 
(Steenstrup),Greenland (Mérch). It probably ranges through- 
out the Arctic seas,
