Var. elegans, Station 13, 690 fms. This variety was 

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

 of Scotland, in 155-632 fms., and previously by me in Shet- 

 land, in 78-100 fms. Another extreme variety (which has a 

 shorter spire and swollen whorls, 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 Biscay, 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 Sabim'y Gray. 



Buccinum Sahinii, Gray in Suppl. to App, of Parry's first Voyage 

 p. cxl (1824). 



Body milk-white : tentacles awl-shaped and slender : e^Jes 

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

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

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

 the water. 



Station 6, 41,0 fms. ; a young living specimen (this was 

 erroneously named F. fenestratus in my Keport 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) ! Baffin Bay and Behring 

 Strait (Gray) ! North Pacific (Wosnessenski). Spitzbergen 

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

 coasts of Russian Lapland (Baer, Middendorff). Vadso, Fin- 

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

 enby) ! 



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

 ebur, F. togatus, and F. Pfaffii, Morch. The epidermis is 

 usually smooth ; but in one of my Spitzbergen specimens it is 

 finely and closely ciliated. The same difference is observable 

 in the epidermis of F.j)rojnnquus,F. i^T/gmceus, and Buccinum 

 grcenlandicum. The comparative length and curvature of the 

 canal are variable characters.
