Mr. Jeffreys on British Mollusca. 107 



name has now been generally adopted for Sowerby's species, it seems 

 a pity, by restoring the latter, to create more confusion, especially 

 as the crinitus of Pennant is different from either of them. 



C. Hanleyi, ii. 398. A specimen in my possession, from theShet- 

 lands, measures no less than f ths of an inch in length, and rather 

 more than ^rd of an inch in breadth. 



Patella vulgata, ii. 421. I was amused at seeing a party enjoying 

 a limpet meal on the httle Isle of Herm. It consisted of a farmer, 

 two of his labourers, and a sheep-dog. This meal formed their din- 

 ner, and took place on a grassy plot near the sea-shore. The limpets 

 were cooked by being laid on the ground in their natural position 

 and covered with a heap of straw which was set fire to. When 

 cooked, they were eaten with bread and butter ; and I can answer 

 for their being well-flavoured. 



Calyptrsea Sinensis, ii. 463. Weymouth (Mr. Thompson) . I found 

 at Serk specimens attached to small loose stones which had scarcely 

 a broader surface than the circumference or base of the shell, and 

 into the sinuosities of which they were closely moulded. It would 

 therefore seem that they do not quit their position, like the limpets, 

 but that their food is brought to them. The nucleus or inner circle 

 of this circumference, showing the point of their attachment, is quite 

 smooth, and apparently worn by the action of the foot ; while the 

 outer circle or rim is sometimes encrusted with Melobesia pohjmorjpha, 

 which thus grows inside the shell. 



Fissurella reticulata, ii. 469. I found two or three shells, by 

 dredging in Guernsey, which agree with the F. costaria of Deshayes. 

 One of them has seventy-two longitudinal ribs and costellse ; but 

 specimens of F. reticulata vary much in this respect, as well as in 

 the comparative convexity and proportions of the shell. They may, 

 however, be distinct species. 



Haliotis tuberculata, ii. 485. The principal use to which the 

 shells now appear to be put in the Channel Isles is to frighten away 

 small birds from the standing corn, — two or three of them being 

 strung together and suspended from a stick, so as to make a clatter 

 when moved by the wind. The importation from southern climes of 

 Meleagrince and other nacreous shells, has superseded the use of 

 our native shells for inlaying and ornamental work. 



Trochus umbilicatus, ii. 521. Var. spira elatiore, umbilico fere 

 clauso. This remarkable variety, which Mr. Hanley noticed as having 

 occurred to him at Herm, is abundant on every part of the coast of 

 Guernsey at low water. Dr. Lukis observes that it inhabits quite a 

 distinct zone from the typical form, and that they are never found 

 together ; and he is inclined to believe that the variety remains 

 under water, while the ordinary kind seems ever endeavouring 

 to crawl out of the vessel in which both are kept. In adult speci- 

 mens the umbilicus is entirely closed, but in the young it is partially 

 open. The animals do not appear to present any difference either 

 in their external form and organs, or in their tongues. Mr. Rupert 

 Jones has found the same variety in Jersey. 



r. lineatus, ii. 525. Weymouth {Mr. Thompsoti).
