324 Dr. Gwyn Jeffreys on 



B. fusifoyme of Kiener, from a specimen in the Massena Col- 

 lection. Another variety of the present species in Holler's 

 collection at Copenhagen is named '' Tritonium Humplirey- 

 sianumy It is also probably the B. horeale of Gray (in the 

 ^ Zoology of Capt. Beech ey's Voyage^), which he refers to a 

 species said to be so named by Leach in the Appendix to 

 Sir John Ross's first voyage ; but I can find no such name in 

 that Appendix. B. groenlandicum of Hancock is a variety of 

 B. glaciale. 



The spawn-capsules are smaller than those of B. uyidatum^ 

 and are sometimes attached to the stalks of seaweeds and to 

 the shells of Balani. 



B. undatum is apparently rare in the arctic seas, although it 

 is occasionally found with B. grcenlandicum. 



Buccinum ciliatum, Fabricius. 

 Tritonium ciliatum, Fabr. Fn. Gr. p. 401. 



Godhavn, 5-20 fms. ; Holsteinborg, 10-35 fms. Green- 

 land (Fabricius and others). Murray Bay, Gulf of St. 

 Lawrence, 112 fms. (Principal Dawson, Whiteaves) ! Spitz- 

 bergen (Torell) ! White Sea and the coasts of Russian 

 Lapland (Von Baer, Middendorff) ; it is the latter's variety 

 horeale of B. tenebrosum of Hancock. 



It is the B. Molleri of Reeve, whose B. ciliatum is B. 

 grcenlandicum. The B, ciliatum of Gould is apparently a 

 variety of the last-named species. 



Buccinum tenue, Gray.
