Mr. H. B. Brady on some Arctic Foraminifera. 417 
Polymorphina compressa, D’Orb. Pulvinulina Karsteni, Reuss. 
Cassidulina levigata, D’ Ord. Nonionina umbilicatula, Mont. 
crassa, D’ Orb. stelligera, D’ Orb. 
Discorbina Wrightii, Brady. Polystomella striatopunctata, 
Truncatulina lobatula, W. & J. & M. 
The three remaining soundings are from somewhat greater 
depths ; and their examination has yielded but a poor list of 
species. Whether this arises from the smaller quantity of 
material secured, or from the less plentiful distribution of 
animal life, may be difficult to decide; but the former is the 
more probable explanation. 
5. “ Soundings, June 19th, lat. 73° 10’ N., long. 50° E. 
Depth 30 fathoms.” Clean siliceous sand with dark fel- 
spathic grains; contained but little evidence of animal life. 
There were a few Rhizopoda, belonging to half a dozen 
species, namely :— 
Miliolina seminulum, Linné. Nonionina scapha, F. & M. 
Verneuilina polystropha, Reuss. Polystomella striatopunctata, F. 
Truncatulina lobatula, W. & J. & M. 
Pulvinulina Karsteni, Reuss. 
6. “Soundings, lat. 70° 45’ N., long. 47° EK. Depth 80 
fathoms.” The material in this case consisted only of a 
pellet of mud weighing about 0-3 gramme, which, after wash- 
ing, left scarcely. any residuum. This, however, yielded 
specimens of two arenaceous species :— 
Haplophragmium glomeratum, Haplophragmium nanum, Brady. 
Brady. 
7. “ Soundings, lat. 74° 16’ N., long. 53° 50’ E. Depth 
90 fathoms.” Quantity of material not much greater than 
the last, contained the following forms :— 
Haplophragmium glomeratum, Nonionina stelligera, D’ Orb. 
Brady. scapha, F. & M, 
Cassidulina crassa, D’ Orb. 
The only species of unusual interest contained in these lists 
is Hippocrepina indivisa, concerning which a note will be 
found on a previous page (p.407). The specimens of Nonio- 
nina scapha often approach in character the variety named by 
Dawson JN. labradorica. It is frequently difficult to decide 
whether some of the flat outspread Nonionine are more cor- 
rectly placed with N. asterizans, Bc Me vor NE stelligera, 
D’Orb.; but as the distinction between the two depends pri- 
marily on the extent to which the stellate sutural limbation is 
developed (a comparatively trivial character), they have been 
associated with similar specimens from the more northern 
stations under the latter species.
