MARSHALL : ON THE BRITISH SPECIES OF BUCCINUM, FUSUS, ETC. 45 



apparently dead and water-worn, yet still containing the animal and 

 operculum. As I have explained with regard to examples of Tmrlms 

 in a similar condition, these have been swallowed by fish and voided 

 again, the action of the gastric fluid having meanwhile destroyed the 

 epidermis. 



F. PROPiNQUUS, Aid. — Not Dublin Bay nor Cork, which localities 

 belong to the next species (Jeffreys) ; Birkdale|(Heathcote); Llandulas 

 (Archer); St. Andrew's (M'Intosh) ; off Peterhead 60 f. ("Triton") ! West 

 Orkneys 45 f. ; and North Rona. In the Report of the " Valorous" 

 Expedition, Gwyn Jeffreys has mistakenly recorded this species from 

 the Bay of Biscay 109-1380 f., by the "Porcupine" Expedition of 

 1870, instead of from the West of Ireland, Stations 24 and 30, by the 

 expedition of 1869; and Canon Norman has also mistakenly recorded it 

 from " N. of Hebrides, 189-530 f., "Porcupine" 1869," instead of 

 "Lightning" Expedition 1868. 



Var. turriia, Sars. — East Shetlands, several specimens from 

 Aberdeen trawl-boats (Simpson) ! Its dimensions are i|-in.by f-in.,the 

 apex is much more pointed than in the type, and it is very rare on our 

 Shetland coasts. One of my specimens is almost smooth. Searles 

 Wood figures a specimen from the Red Crag (pi. ii, fig. 15) as what 

 he considers " an abnormal form of F. propinquus." It is not very well 

 executed, but fairly represents this variety. Various misconceptions 

 have centred round the identity of this shell. The specimens ascribed 

 to it by Mr. H. K. Jordan (') are not this variety, but small typical speci- 

 mens. Some writers prefer to consider it a variety of i^. foiiuosu>i, G. O. Sars, 

 and it is so described and figured by him, though from a poor specimen 

 minus the apex. ('^) The difference between Sars' var. turritus and var. 

 attenuatus (•') is not apparent, certainly not in the figures, and I con- 

 sider them the same thing; while Gwyn Jeffreys held that F. tortuosus, 

 G. O. Sars (non Reeve, which is F. sahini, Gray) is another variety of 

 F. 'propin(pm>< ("*). However that may be, from my own specimens I 

 can easily graduate vars. furrifufundaffe/matus 'uitotypica.\F.2Jropin(piU(t, 

 from which they do not differ in any particular except that of propor- 

 tion. Sars was mistaken in quoting F. attenuatus, Jeffr. as a synonym 

 of his var. attenuatus ; they have nothing in common except the name. 

 The latter, as well as forfuo.^us and turritus, are attenuated at each end, 

 which gives them a cylindrical outline, whereas F. attenuatus, Jeffr., 

 and F. consirnilis. Marsh., are attenuated in the spire only, but have a
