122 EDIBLE BRITISH MOLLUSKS. 



without any passage leading to them.* Those consist- 

 ing of chambers and a long entrance passage, covered 

 by slabs, within a large tumulus of earth, as at Wellow, 

 near Stoney Littleton ; at Rodmarton ; at Uley ; and at 

 Nympsfield, are called Tumps. In speaking of Crom- 

 lechs, in the Channel Islands, I do not therefore allude 

 to monuments such as we call Cromlechs ; which last, 

 though probably sepulchral, have not yet been found to

Necklaces of limpets and other shells, strung together

Limpet shells are also used for mortar. 



In the island of Herm, near Guernsey, poultry are 

 fed on Patella vulgata ; but it is said that they will not 

 touch Patella athletica, which is also considered too 

 tough for bait. 



Sea-birds feed on the Patella, and Mr. Gatcombe, in

 the bird. 



The French call this shell Upas, Patelle, Jambe, ceil
