B.fnsiforme of Kicncr, from a specimen in tlie ^[assena Col- 

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

 collection at Copenhagen is named "■ Tritoniuia Ilumphrey- 

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

 * Zoology of Capt. Beechey'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. grcenlandicum of Hancock is a variety of 

 B. (jlaciale. 



The spawn-capsules are smaller than those of B. iindatum, 

 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. granlandicum.

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) ! AVhite Sea and the coasts of Russian 

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

 horeale of B. tenehrosum of Hancock. 



It is the B. M'olleri 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.
