JORDAN: ON THE GENUS FUSITS. 233 



then I have obtained it from the long line fishermen from 

 north of Unst, 90 fathoms. 

 F. gracilis var. convoluta.— Massive sub-cylindrical speci- 

 mens 375 inches in length from Wick, N.B. 



7. — Fusus propinquus, Alder. 

 This species has a northern range, but it has been taken in 

 the Bay of Biscay, 109 — 1380 fathoms. Mr. J. T. Marshall 

 dredged a good many specimens on the Dogger Bank off the 

 Yorkshire coast. The localities ' Cork ' and ' Dublin Bay ' 

 given in " British Conchology " are erroneous. It is a difficult 

 shell to obtain as it so much resembles — to the uninitiated eye 

 — the common J^. gracilis ; consequently the fishermen do not 

 distinguish the shell and throw it away with the ' common herd.' 

 My collection contains two examples which have no epid- 

 ermis, the surface of the shells is polished. 

 F. propinquus var turrita. — A few specimens only, from 

 70 fms., on the east of Shetland in company with F. gracilis 

 var. coulsoni with which it agrees closely in shape, but the 

 more turrited form and, above all, the nucleus of F. propin- 

 quus serve to distinguish it. 



8. — Fusus JefTreysianus, Fischer. 



Fine specimens, both in size and condition, have been 

 taken off the Waterford Coast in 20 — 30 fathoms, soft ground, 

 and several specimens were brought to me from the beach near 

 Wexford, having been cast up by a storm. Also in 40 fathoms 

 15—20 miles off Milford Haven. The Irish specimens 

 (especially those from the deep water) are thinner and have a 

 paler-coloured epidermis than the South Devon examples. 

 About twenty-four years ago this shell came under my notice 

 and believing it to be an undescribed species I sent the examples 

 to the late Dr. Gvvyn Jeffreys, who forwarded them to Dr. Joshua 

 Alder for his opinion : Alder returned the specimens with the 

 expression " not xxvj propinquus.'''' 



I took no immediate steps to describe and name the shell
