Somewhat rare; from shelly sand, Hunde Islands, Disco Bay (Dr. P. C. Sutherland), 
at 60-70 fathoms; also from Baffin’s Bay, lat. 75° 10' N., long. 60° 10' W. (Parry’s 
soundings). 
Nodosaria ( Dentalina ) guttifera , D’Orbigny. Plate XIII. fig. 11 (Arctic). 
Passing out of Dentalina communis towards the perfectly moniliform subvarieties of 
Nodosaria, we have this loosely grown Dentaline form (D. guttifera, D’Orb. For. Foss. 
Vien, pi. 2. fig. 13), near D. Pyrula, D’Orb. It varies much in the gibbosity of the 
chambers. 
Though curved, this Dentalina has an almost central aperture, as shown by a broken 
terminal chamber not here figured. (See Ann. Nat. Hist. 2 ser. vol. xix. pi. 19. figs. 4, 5). 
We have Dentalina guttifera from Norway at West Fjord (Nordland), from a sandy 
bottom at 60 fathoms (MacAndrew and Barrett) ; and from a muddy bottom (Arctic 
Circle) at 160 fathoms. These are two fragments of two large specimens. There is 
no doubt that in this, as in other instances, the small quantity of materials obtained 
necessarily limited the number of individuals. 
Forms similar or allied to this occur both in existing sea-bottoms and in fossil deposits 
with much the same range as that of D. communis ; but they are not so common. 
Vaginulina linearis , Montagu, sp. Plate XIII. figs. 12 a, 12 b, 13 a, 13 b (Arctic). 
The straight varieties of Marginulina Baphanus (or the flattened forms of Nodosaria 
Baphanus, with excentric septal apertures) are known as Vaginulince ; a large group, 
widely extending in time and space ; especially abundant in the Gault and Chalk-marl. 
Of these Vaginulince, V. Legumen, Linn., is the most common among the recent ; and 
the Adriatic Sea may be said to be its home. The subvarieties with linear costation 
are very variable as to their amount of ornament; but they may be all comprised under 
Montagu’s name V. linearis. (See Williamson’s ‘ Monograph Recent Foram. Great Britain,’ 
p. 23, pi. 2. figs. 46-28.) 
We have two small specimens from the mixed sands dredged up between Drontheim 
and North Cape (MacAndrew and Barrett). 
This is not an uncommon form, occurring at moderate depths. It does not appear to 
be so common in the fossil as in the recent state, though it is not without close allies in 
the clays and other deposits of the Secondary and Tertiary formations. 
Marginulina Lituus, D’Orbigny. Plate XIII. figs. 14 a, 14 b (Arctic). 
One of Soldani’s figured Foraminifera from the Adriatic, named Marginulina Lituus 
by D’Orbigny (Annales des Sciences Nat. vol. vii. p. 259. No. 11), well represents our spe- 
cimen from the Arctic Ocean. This may be looked at as a passage-form from a simple 
Vaginulina, oval in section and but little altered from Dentalina, into Cristellaria, through 
innumerable gentle gradations ; or it may be regarded as a medium between Cristellaria 
and Marginulina ; and so leading to Nodosaria, through the flattened forms. Having
