Dr.. Leches Buccinopsis ovum (Novaja Semlja & Jeni- 
se} Hafsmoll. Pag. 59) maa utvivlsomt komme ind under 
denne Varietet, uagtet han vistnok ogsaa har opført B. 
ciliatum, var. lævior, men Tegningerne af Tænderne viser 
noksom, at han ikke har havt en Buccmopsis for sig. 
Buccinum groenlandicum, Chmn. 
Conch. Cab. X, Pag. 177, Fig. 144. 
Forekomst: Tromsø, Hammerfest, Vardø (littoral); 
Norskøerne, Adventbay, Magdalenbay; fra 10 til 60 Fayne: 
Paa de 3 sidste Lokaliteter (Spitzbergen) forekom en 
smuk, baandet Varietet. 
Var. acuta, nob. Pi. II, Fig. 17 
langt uddraget, konisk Spir og flade Vindinger. 
Et Exemplar fra Hammerfest (littoral). 
Det er maaske nærmere en Monstrositet end Varietet 
og er noget lignende for B. groenlandicum som aceuninatun 
for B. undatum. 
Var. hybrida, nob. 
Formen konisk, har i Regelen Længdefolde, men min- 
dre stærkt udviklet end hos B. undatum. Spiralribberne er 
paa Tophvirvlerne kraftige, men gaar paa Hoyedvindingen 
som oftest over til obscure Folde; Epidermis haaret. 
Hammerfest (littoral). 
Denne Form opfatter jeg som en Hybrid imellem B. 
undatum og groenlandicum. To Exemplarer fra Hammer- 
fest har Spiret fra B. wndatum, men Hovedvindingen fra 
B. groenlandicum, nogle andre mangle igjen fuldstændig 
Længdefolderne, men har dog i sim Sculptur en større Til- 
nærmelse til B. wndatum. Der er i det Hele taget den 
fuldstændigste Overgang mellem begge Arter. 
Buccinum conoideum, Sars (1. c. Tab. 24, Fig. 7) 
holder jeg for at tilhøre den hybride Form, men ligger B. 
undatum nærmest. 
Var. sericata (?), Tab. III, Fig. 19. 
Buccmum sericatum, Hancock. Ann. & Mag. XVIII, PI. 
V, Fig. 6. 
Stat. 192, 267 og 270; fra 136 til 649 Fayne. 
Skallen er tynd, halv gjennemsigtig, hvid med stærkt 
bugede Vindinger. Sculpturen bestaar af tætte, svage Spi- 
ral- og Længdestriæ, der danne et fint Netværk over hele 
Skallen. Epidermis er tæt haaret, næsten ulden. 
Dette er ikke Hancocks typiske B. sericatum, men 
adskiller sig fra denne baade i Form og Sculptur. Jeg er 
forøvrigt aldeles ikke sikker paa, om vi ikke her har en

Dr. Leche's Buccinopsis ovum (Novaja Semlja & Jeni- 
sej Hafsmoll., p. 59) should unquestionably be referred to 
this variety, notwithstanding his having also noted B. cilia- 
tum, var. lævior; but his drawings of the teeth plainly show 
he has not had a Buccinopsis before him. 
Buccinum groenlandicum, Chmn. 
Conch. Cab, X, pag. 177, fig. 144. 
Habitat: — Tromsø, Hammerfest, Vardø (littoral); 
the Norway Islands, Advent Bay, Magdalena Bay; from 
10 to 60 fathoms. 
In the 3 last-mentioned localities occurred a finely 
banded variety. 
Var. acuta, nob. Pl. III, fig. 17. 
very elongate, with a conical spire and flat whorls. 
Only one specimen was obtained at Hammerfest (littoral). 
This form should perhaps be regarded rather as a 
monstrosity than a variety; it bears about the same relation 
to B. groenlandicum as does B. accummatum to B.undatum. 
Var. hybrida, nob. 
Conical in form, and as a rule with longitudinal folds, 
though less developed than in B. undatum; the spiral ribs 
prominent on the top whorls, but on the body-whorl gene- 
rally passing into obscure folds; epidermis hispid. 
Hammerfest (littoral). 
This form I conceive to be a hybrid between B. wn- 
datum and B. groenlandicum. Two specimens from Hammer- 
fest have the spire as in B. undatum, but the head-whorl 
as in B. groenlandicum; in some others the longitudinal 
folds are wanting altogether, but the sculpture on the shell 
denotes a nearer approach to B. undatum. On the whole, 
there is an undoubted transition between the two species. 
Buccinum conoideum, Sars (1. c., Pl. 24, fig. 7), I re- 
gard as a hybrid, approximating closest B. undatum.

Habitat: — Stats. 192, 267, 270; from 136 to 649 
fathoms, 
Shell thin, semi-translucent, white, with tumid whorls. 
The sculpture occurs as faint and closely disposed spiral 
and longitudinal striæ, which give to the shell the appearance 
of a fine network. Bpidermis thickly covered with hairs, 
almost woolly. 
This is not Hancock’s typical B. sericatum, from which 
it differs alike in form and in the character of the sculpture. 
For the rest, I am by no means sure it is not a form per-
