26 THE MOLLUSCA OF THE FIRTH OF CLYDE. 
and down to 10 fathoms. Large specimens are thrown up 
on the beach in many places; especially common under such 
conditions at Fintry and other bays on the west side of 
Cumbrae. Fine living specimens may be obtained at the 
very lowest ebb of spring tides between Fintry and Shell- 
bole Bays. From this locality I have my largest specimens, 
measuring 2} x 24 inches. The fishermen at Millport have 
a name for this shell which savours too much of the older 
zoological authors to be printed in plain English. 
Specimens from this district are seldom rayed so brightly 
as those from more southern latitudes; but the northern 
shells are larger. 
British distribution—Throughout our seas ; common 
everywhere in sandy bays. 
Foreign localities—Norway (Lovén, and others), northern 
and southern Spain and Portugal MW‘ Andrew), and the Medi- 
terranean Sea (Payraudeau, and others). 
* Venus lincta, Pultency. 
Venus lupinus, Poli; Venus sinuata, Turton ; Cytherea 
lunaris and C. lincta, Lamarck ; Artemis lincta, Forbes and 
Hunley. 
Habitat—In deeper water than V. exoleta, in sand and 
nullipore; very common almost everywhere; fine living 
specimens, however, are scarce. 
British distr ibution.—Throughout all our seas; very 
common. 
Foreign localities—Norway (Lovén), northern and south- 
ern Spain and Portugal (/‘Andiew) ; also both sides of the 
Mediterranean and Agean Seas. 
* Venus fasciata, Da Costa. 
Pectunculus fasciatus, Da Costa ; Venus paphia, Pulteney. 
Habitat—I have taken this species under stones a little 
above low water of neap tides at Battery Point, Cumbrae ; 
it is generally obtained, however, in 6 to 15 fathoms, in 
gravelly sand. Common on Tan Spit and west coast of 
Cumbrae; also at Bogany, Craigmore, and Ascog in Bute. 
Specimens ornamented with numerous and bright rays, and 
others having a greater or lesser number of ribs, are occa- 
sionally met with. These differences are hardly of varietal 
rank. 
British distribution.—Everywhere throughout our seas; 
a common shell.
