(Beck) Mørch (Cat. Moll. Spitzb., Pag. 14). Bu oddt anid: 
lertid denne er identisk med Verkriizens Art har jeg ikke 
hayt Anledning tilfredsstillende at faa undersøgt. Dr. W. 
Leche (1. ce. Pag. 64) holder dem for Synonymer. 
Fra B. Humphreysianwn adskiller den sig ved en 
grovere Seulptur paa Tophvirvlerne. Udenfor Norge er 
Arten ikke med Sikkerhed kjendt. 
Buccinum Humphreysianum, Bennett. 
Zool. Journ. I, Pag. 298, Pl. 30. 
Forekomst: Station 195, 107 Favne. 
Et ungt dødt, men vel vedligeholdt Exemplar. 
Prof. Sars har fundet denne Art i Finmarken, dog 
kun i smaa, ikke udviklede Exemplareyr. 
Ovennæynte Station ligger nær under Tide Bredde- 
grad, er Artens yderste kjendte Nordgrændse.

Buccinum hydrophanum, Hanck. Ann. & Mag. N. H. XVII, 
1846, Pag. 325, PI. V, Fig. 7. 
Forekomst: Stat. 18, 124, 164, 192, 200, 223, 251, 
267, 326, 338, 357, 363, 366. Fra 30 til 649. Favne 
Den typiske Form er forholdsvis sjelden og forekom 
kun paa Stat. 251 — 634 Favne og 366 (Magdalenebay, 
Spitsbergen) 60 Favne. 
Var. tumidula, Fie. 21. 
B. tumidulum, G. O. Sars, 1. c. Pag. 263, Pl. 25, Fig. 5, 6, 
og Var. elata, nob., Fig. 20. 
er de almindeligste Former og findes meget talrig sammen 
paa de middelmaadige Dyb over hele Ishavet. 
Formen elata har et langt uddraget Spir og Mund- 
aabningen meget kortere end Spiret. 
Var. Mørchi, Fig. 22. 
B. Mørchi, Friele, *Prelim. Rep.” Pag. 4. 
Formen konisk, flade Vindinger, violet farvet. 
Denne Varietet synes særlig at høre de større Dyb til 
og forekom paa Stationerne 18, 124, 200, 164 og 192, alt- 
saa imellem 350 og 650 Favne. 
(Beck) Möreh (Cat. Moll. Spitzb., p. 14); but whether 
identical with Verkriizen’s species, I have not had sufficient 
opportunity of deciding. Dr. W. Leche (1. c., p. 64) re- 
gards them as synonyms. 
From B. Humphreysianum it is distinguished by the 
coarser sculpturing of the top whorls. Elsewhere than on 
the coast of Norway, this species has not been recorded 
with certainty. 
Buccinum Humphreysianum, Bennett. 
Zool. Journ. I, p. 298, Pl. 30. 
Habitat: — Station 195, at a depth of 107 fathoms. 
A young specimen, dead, but in a good state of pres- 
ervation. 
Professor G. O. Sars has met with this species in Fin- 
mark, but only represented by small and immature examples. 
Station 195 lies but a short distance from the 71st 
parallel of latitude, which constitutes the extreme northern 
limit of distribution for this species.

Buccinum hydrophanum, Hanck. Ann. & Mag. N. H. XVII, 
ETO 249 ol OV OC 
Habitat: — Stats. 18, 124, 164, 192, 200, 223, 251, 
267, 326, 338, 357, 363, 366; from 30 to 649 fathoms. 
The typical form is comparatively rare; it was met 
with only at Station 251, in 634 fathoms, and at Stat. 366 
(Magdalena Bay, Spitzbergen), in 60 fathoms. 
Var. tumidula, fig. 21. 
B. tumidulum, G. O. Sars, 1. c., p. 263, Pl. 25, figs. 5, 6, 
and Var. elata, nob., fig. 20, 
are the most frequent forms; they occur abundantly together 
at moderate depths throughout the whole of the Arctic Ocean. 
The form elata has a long, produced spire, than which 
the aperture is much shorter. 
Var. Mörchi, fig. 22. Å 
B. Mörchi, Friele, “Prelim. Rep.,” p. 4. 
Form conical, flat whorls, violet-coloured. 
This variety would appear to occur chiefly in the deeper 
strata; it was brought up at Stats. 18, 124, 200, 164, and 
192, from depths varying between 350 and 650 fathoms.
