Fiuu* beniirietisu, Kinff in Ann. Sc Mag. Nat. Hist, xviii. p. 246 

 (184«>. 



Var. eleganSy Station 13, 690 tms. 'Y\\\a variety wa.s 

 dredged in the 'Porcupine' Expedition, 1869, ofi' the north 

 of Seothmd, in 15.5-632 fnis., and previously b}' nic in Shet- 

 land, in 78-100 tms. Another extreme variety (wliich has a 

 shorter .'^pire and .swollen whorl.>^, and is a thin and delicate 

 shell) was dredged in the same expedition, in 203-290 fms. ; 

 and it was procured in the late Norwegian Expedition. The 

 latter variety may be called injiata. The typical form was 

 dredged in the ' Porcupine' Expedition of 1869 and 1870, 

 Bay of Bi.scay, at depths of from 90 to 690 fms. * Lightning ' 

 Expedition, 189 and 500 fms. Yorkshire, Northumberland, 

 Aberdeenshire, Shetland, Norway, and Arcachon, 50—140 fms. 



It is the Tritonium islandicum of Loven, not Fusus islandi- 

 cus of Chemnitz. 



Fusus Sabinij Gray. 



Buccinum Sabinii, Gray in Suppl. to App. of Parry's fir.'^t ^'oyage 

 p. cxl (1824). 



Body milk-white : tentacles awl-shaped and slender : eyes 

 placed on bulbs at the outer base of the tentacles : foot broad 

 and thick, semicircular and double-edged in front, with short 

 angular comers, rounded behind. Active, and crawls out of 

 the water. 



Station 6, 410 fms. ; a young living specimen (this was 

 erroneously named F. fenestratus in my Report to the Royal 

 Society, Proc. vol. xxv. no 173, pp. 183 and 189) : also St. 1, 

 175 fms. (fragments); 12, 1450 fms. (fragments). Davis 

 Strait (Hancock and others). Melville Bay, 100 fms. (Walker). 

 Gulf of St. Lawrence (Whiteaves) ! Batiin Bay and Behring 

 Strait (Gray) ! Nf»rth Pacific (Wosnessenski). S})itzbergen 

 (Torell) ! Iceland (Morch, as F. tortuosiis). White Sea and 

 coasts of Russian La])land (Baer, ^lidderMjJorff). Yadsii, Fin- 

 mark (G. O. Sars, Verkriizen). Fossil: Bridlington (Leck- 

 enby) ! 



Synonyms : F. tortuosus and F. spitzhcrgensis, Reeve ; F. 

 ebur, F. tojatus, and F. Pfof/'i, M'irch. Tiic epidermis is 

 usually smooth ; but in one of my Sj)itzbcrgen specimens it is 

 finely and closely ciliated. The same difference is observable 

 in the epidermis of F. propinquus^ F. pygimrus^ and Buccinum 

 gra^idandicum. The comparative length and curvature of the 

 canal are variable characters.
