Mr. Jeffreys on British Mollusca. 193 



M. barbata, ii. 190. Guernsey (/. G. J.); Jersey (Rev. A. M. 

 Norman). 



M. cuprea, Ann. Nat. Hist. 3rd ser. vol. iii. No. 13. p. 40 ; 

 Sow. III. bid. pi. 7. f. 11. Tbe indigenousness of this species is 

 somewhat doubtful, as it now turns out that Mr. Bean's specimens 

 were taken by Mr. Alfred Roberts, a bird-stuffer at Scarborough, 

 from the crop of a Brent-goose (instead of a Sanderling) which had 

 been shot there during the severe winter of 18.55. Roberts appears 

 to have had good cause for remembering the circumstance, from 

 having lost his Sunday dinner. Having heard that the Brent-goose 

 was "an excellent-eating bird," he depended upon this, and bought 

 nothing on the Saturday ; and, to his disgust, when his wife attempted 

 to prepare it for the spit, the ulva on which it had fed smelt so 

 very "loud," that bread and cheese had to be substituted. The 

 Brent-goose is a northern bird, and an occasional visitant to this 

 country. The shells retain all the original brilliancy of gloss and 

 colour, and they may certainly have been picked up on the British 

 coast. 



Crenella rhombea, ii. 208. Gronville Bay, Jersey (Rev. A. M. 

 Norman) . 



Area lactea, ii. 238. In dredged sand from Belfast Bay. 



Pecten furtivus, Lov. (P. striatus, var., ii. 284). A single valve 

 occurred to me in dredged sand from Belfast Bay ; and I have since 

 found it alive, and not unfrequently, in the Irish Sea, off the coast 

 of Antrim. 



P. opercularis, ii. 299. The very young have a rhomboidal form, 

 and the lower or flat valve is much smaller than the other (which 

 overlaps it) and is perfectly smooth. The ribs do not at first appear 

 on the larger valve, but are preceded by a shagreen reticulation. 



Anomia ephippium, ii. 325. Specimens which I found many 

 years ago in Swansea Bay, on a mussel bed which was uncovered at 

 a very low spring tide, present the anomalous character of having 

 the foramen in the lower or flat valve closed by a series of convex 

 layers of thin shelly matter. They were alive, and attached to the 

 mussels by the byssal threads of the latter mollusks ; and it appeared 

 to me that, having been detached from the oysters or stones to which 

 they were originally fixed, and thus deprived of their plugs, they 

 filled up the openings in the above manner for the sake of protection 

 against whelks and other enemies, being securely held by the mussel 

 moorings. 



Gasteropoda Prosobranchiata. 



Chiton gracilis, Ann. Nat. Hist. 3rd ser. vol. iii. No. 14. p. 106. 

 Gronville Bay, Jersey, with C. discrepans ; rare (Rev. A. M. Nor- 

 man). 



C. Hanleyi, ii. 398. In deep water on the north coast of Ireland, 

 with Pholadidea papyracea (J. G. J.). It is recorded in the ' Journal 

 de Conchyliologie ' as having been taken at the Antilles. 



C. cancellatus, ii. 410. With the last, at low water (Rev. A. M. 

 Norman). Irish coast, off Lame, in about 18 fathoms (J. G. J.),
