Mr. H. B. Brady on some Arctic Foraminifera. 399 
N. No. 522. 17th June, 1873. Franz-Josef Land. Depth 
222 metres (121 fathoms), mud. 
Fine, white, siliceous sand, with numerous grains of mag- 
netite and a little red earth. Many of the calcareous Forami- 
nifera are stained brown by this or some similar colouring- 
matter, 
Not very rich in organisms ; the Foraminifera belong chiefly 
to the smaller species. 
O. No. 523. 20th June, 1873. Franz-Josef Land. Depth 
22() metres (120 fathoms), dark-coloured mud. 
Siliceous sand with red earth; quantity of material very 
small. List of organisms manifestly imperfect. 
P. No. 525. 12th July, 1873. Franz-Josef Land. Depth 
265 metres (145 fathoms), light-coloured mud. 
Siliceous sand, with fragments of soft brown rock and some 
red earth, also bits of hypersthene or epidote. 
Affords a good representative list of Foraminifera. Some 
valves of Cythere mirabilis, Jones, were also found. 
On reference to the map it will be seen that these soundings 
refer to two tolerably distinct areas. ‘The more southern area, 
represented by Nos. 500-506 (A—F), embraces the western 
shores of Novaya Zemlya between latitudes 74° and 77° N. ; 
whilst the more northern, represented by Nos. 514-525 (G= 
P), lies in the latitude of Franz-Josef Land—that is to say, 
at about 79° or 80° N. 
There is not much that is new to be said respecting the 
general aspect of the Rhizopod-fauna brought into view by 
the careful investigation to which the material has been sub- 
jected. The total number of species obtained from it is 
seventy-one, which suggests a somewhat greater variety in 
the Rhizopod life of the eastern arctic area than exists in the 
western region explored by the British North-Polar expedition 
of 1875-76. The soundings obtained on the latter occasion 
yielded on examination fifty-three species of Foraminifera. 
Too much reliance must not be placed upon these figures in 
either case, inasmuch as the total amount of material that has 
as yet been secured is insufficient to furnish what can be re- 
arded as even approximately exhaustive lists. 
The Distribution Table, which will be found facing page 
418, indicates the prevalence over the whole area of certain. 
species which previous researches had shown to be common 
denizens of polar seas—namely Globigerina bulloides and its 
arctic variety, Pulvinulina Karstent, Truncatulina lobatula, 
Cassidulina: levigata, Cassidulina crassa, and Polystomella 
striatopunctata ; but over this eastern ground there appear in
