24 EDIBLE BRITISH MOLLUSCA. 



in Spain (where it is known by the following names, 

 Arolas, Orolas, and Navallon), viz., Lutraria elliptica, 

 very unlike the Madridce in appearance, and not 

 tempting to look at. It is a broad flattish shell, about 

 live inches long, and three in height, with a long tube, 

 something resembling Mya arenaria. It lives in 

 muddy estuaries, and at the mouths of rivers, buried 

 to the depth of one and a half to two feet ; and I have 

 had some fine specimens from the mouth of the Towy, 

 in Carmarthenshire. 



Mr. Dennis * says the Lutrarice are called Clumps at 

 Herm, and I am told by Mr. Morton, that the fisher- 

 men in Jersey know them by the name of Horse-shoes. 

 In Devonshire they are called Glams. In cooking 

 them, they are first boiled, then taken out of their 

 shells and fried. 



Lutraria oblong a, whicli is a common species in 

 some of the little muddy estuaries near Croisic and 

 Piriac, on the coast of the Loire Inferieure, is said by 

 M, Cailliaud to be very generally eaten, but it is a 

 rare species with us, though it has been taken on the 

 Devon, Cornwall, and Dorset coasts. At Mahon the 

 name for it is Guitzii ; Quiquirig alias, and Cobras at 

 Santander, and Ropamaceiras at Vigo.f 



Mr. J. K. Lord states that in British Columbia and 

 Vancouver's Island the large Lutraria Maxima, called 

 the great clam, or otter-shell, is one of the staple 

 articles of winter food on which the Indian tribes who 

 inhabit the North- West Coast of America in a great 

 measure depend. The squaws fish for them, as it is
