2, THE MOLLUSCA OF THE FIRTH OF CLYDE. 
also (I am told) at intervals along the whole coast of Ayr. 
Our beds, however, will not compare in size or value with 
many along the coasts of England and Wales. The gastro- 
nomic merits of the cockle have been well known and appre- 
ciated by man for untold ages; birds do not despise it; and 
the predatory mollusca have a special penchant for this juicy 
morsel. Yet in spite of such persecution it still survives, 
possibly in as great abundance as ever—a good example of 
ss the seas abundant progeny, 
Whose fruitfull seede farre passeth those in land.” 
British distribution—KEverywhere on suitable ground ; 
one of our commonest bivalves. 
Foreign localities—Iceland (Mohr), Norway (Lovén, and 
others), Spain, Portugal, and Mogador (M‘Andrew), Aigean 
(Forbes), Caspian Sea (Middendorff, and others). 
Cardium minimum, Philippi. 
Cardium Suecicum, Lovén. 
Habitat—In sand and nullipore; apparently scarce. I 
have taken it living on the Tan Spit, Cumbrae, and at 
Bogany Point, Bute; but have only obtained some half- 
dozen specimens. 
British distvibution.—Chiefly on the western and northern 
coasts of Scotland, and in most parts of Ireland ; but every- 
where scarce. 
Foreign localities—Norway (Lovén, and others), Brittany 
(Carlliawd), Spain and Portugal (WA ndrew), Mediterranean 
and Aigean (Naves, and others). 
* Cardium Norvegicum, Spengler. 
Pectunculus maximus, Lister; Cardiuim levigatum, Pennant 
(not C. leevigatum of Line); Cardium serratum, Lamarck; 
Cardium oblongum, Brown. 
Habitat—Kverywhere throughout the district, in sand 
and nullipore, in 8 to 30 fathoms; not uncommon. Toward, 
Bogany, and the Ascog shore, in Bute, and Tan Spit, Cumbrae, 
may be named as localities where this species may readily 
be found. 
British distribution.— Everywhere throughout the British 
seas, in sand, nullipore, and gravel. 
Foreign localities—Norway (Lovén, and others), Spain, 
Portugal, Canaries, and Madeira (‘A ndrew), Mediterranean 
(Martin, and others).
