Mr. H. B. Brady on some Arctic Foraminifera. 405 
the summer of 1880 (lat. 59° 37! N., long. 7° 19! W.), BR. 
diflugiformis was found in abundance, whilst R. scorpcwrus 
was entirely absent. 
15. Reophax fusiformis, Williamson, sp. 
Proteonina fusiformis, Williamson, 1858, Rec. For. Gt. Br. p. 1, pl. i. 
fig. 1. 
A starved variety of F. scorpiurus ; occurs in the shallow 
water of the Matyushin Shar. 
16. Reophax scorpiurus, De Montfort. 
Reophax scorpiurus, De Montfort, 1808, Conchyl. Systém. vol. i. p. 330, 
88° genre. 
Very common over the whole area. 
17. Reophax nodulosa, Brady. 
Reophax nodulosa, Brady, 1879, Quart. Journ. Micr. Sci. vol. xix. n. s. 
p- 52, pl. iv. figs. 7, 8. 
Small specimens occur in most of the soundings on the 
shores of Franz-Josef Land ; but it is absent from those further 
south. It is nevertheless a very widely distributed species, 
and specimens an inch (25 millim.) or more in length have 
been found in some of the ‘ Challenger’ deep-water dredgings. 
18. Reophax arctica, sp.nov. (Pl. XXI. fig. 2 a, b.) 
Test elongate, tapering, often more or less irregular, com- 
pressed, only slightly constricted at the septal lines. Seg- 
ments numerous ; septation indistinct ; aperture simple ; walls 
arenaceous, very thin. Length 0°3 millim. ~ 
This is an exceedingly minute and obscure species, which 
may be regarded as the sandy isomorph of Lingulina. With 
the exception of a single specimen from Station 504, and one 
which had been previously recorded, without a specific name, 
from Capt. Markham’s soundings, all the specimens are from 
Station 503; so that the distribution appears confined to the 
Novaya-Zemlya Sea. 
HAPLOPHRAGMIUM, Reuss. 
19. Haplophragmium canariense, D’Orbigny, sp. 
Nonionina canariensis, 1)’Orbigny, 1839, Foram. Canaries, p. 128, pl. ii. 
figs. 83, 34. | 
A very widely distributed species; some of the more 
northern specimens are rougher and thicker-shelled than 
usual.
