Mr. Blackburn, in bis ^ Travelling in Spain in tbe Pre-

Red-nosed Cockle . — Shell nearly 3 inches in length, and 
.2 in breadth ; very solid, subrotund, opaque, with 21 or

of 1862, the beach was quite strewn with broken single

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-

of a most brilliant crimson. This foot terminates in a
