IIG Mr. Jeffreys o» British Mollusca. 



Mr. Woodward has undertaken to describe it, with other Norwegian 

 shells, in the ' iVnnals.'

Mr. Hyndman discovered two specimens in shell-sand which had 

 been dredged from the Turbot Bank in Belfast Bay, and obligingly 

 presented me with the one above described. Both are worn shells, 

 and neither of them is quite perfect ; but they cannot be mistaken 

 for any other species. They have somewhat the appearance of the 

 Strombifs Turboformis of Montagu (Suppl. p. 110) ; but the latter 

 wants the sjiiral intercostal striae and the basal keel, which are evi- 

 dent in this. 



Buccinum undatum, iii. 401. I found a dwarf and thin variety 

 on the shores of the Solent Water at Southampton, — a full-grown 

 specimen measuring not quite an inch and a quarter in length. Other 

 species iu the same locality are depauperated, perhaps owing to the 

 chemical nature or quality of the water. 



B. ciliatum. Tritonium ciliatum, Fabr. F. G. p. 401. no. 402. 

 Mixed with the deep-water variety of B. undatum from the Shet- 

 lands, I found an adult and several half-grown specimens of the 

 above distinct and remarkable species. It is rather more ventricose 

 than the variety of B. undatum, and the transverse striae are much 

 more numerous ; but the especial character which distinguishes the 

 two species (as Fabricius remarked) is that the epidermis in this is 

 raised into short close-set hair-like tufts. It appears to be the same 

 species as that which Professor E. Forbes noticed and figured in his 

 " Records of Dredging" (Mag. of Nat. Hist. vol. viii. p. 593. fig. 62), 

 and for which he suggested the name of " Zetlandicum,'" but which, 

 in a subsequent part of the same paper, he considered, as well as 

 Buccinum fusifoi'me, to be only varieties of ^. undatum. This spe- 

 cies cannot be identical with B. Hiimphreysianvm, as conjectured by 

 the authors of the 'British Mollusca' (iii. 411, foot-note), because 

 the latter never has any epidermis, even in the living state. 



B. acuminatum (Broderip), Zool. Journ. v. p. 44. B. undatum, 

 monstr. B. M. iii. 405. This form appears to he constant, but rare ; 

 and I believe it constitutes a distinct species. I have specimens from 

 Cork and the mouth of the Thames. The typical specimen in the 

 British Museum is said to have cost 3612, being the highest price I 

 have known to be paid for a British shell. 



Fusus Islandicus, iii. 416. Weymouth (Mr. Thompson). 



F. propinquus, iii. 419. With the ordinary form, from deep 

 water in the Shetlands, I observed a monstrosity which appears to 

 agree with the description of Mr. Alder's variety, noticed at p. 420.
