CARDIAD^. COCKLE. 37 



Mr. Blackburn, in his ' Travelling in Spain in the Pre- 

 sent Day/ says, that one of the best dishes at Seville is 

 composed of rice, pimentoes, cockles (including sand

Cardium kusticum or tuberculatum, Linnaeus. 

 Red-nosed Cockle. — Shell nearly 3 inches in length, and 

 2 in breadth ; very solid, subrotund, opaque, with 21 or 

 more broad ribs which radiate from the beaks, with 

 knots or tubercles on them, which on the anterior slope

 prominent; beaks incurved. Ligament large, central 

 tooth large, and the lateral teeth remote.

 of 1862, the beach was quite strewn with broken single 

 valves of this cockle, and there had evidently been quan-

 to a rich-rufous brown; sometimes there is a white band 

 round the shell and one of a dark chestnut-brown to- 

 wards the margins. The colouring of the animal is 

 most beautiful, the body being of a pink or pale ver- 

 milion, the mantle yellow or reddish, and the long foot 

 of a most brilliant crimson. This foot terminates in a
