REPORT OR THE FORAMINIFERA.

12th. The Foraminifera collected vary but little over the whole area. The Globigerince 
are all referrible to Globigerina bulloides, Globigerina injlata, and Orbulina universa. 
The specimens are small and thin-shelled ; those of Globigerina are non-spinous, whilst 
the Orbulince are sometimes armed with very short delicate spines. No specimens of 
Globigerina borealis , and no Pulvinulince occur in any of the surface-mountings. 
In the summer of 1882 a further investigation of the Faroe Channel was carried out 
in H.M.S. “Triton,” and it is worthy of remark that the most prominent surface Fora- 
minifer obtained by Mr. Murray on that occasion was Hastigerina pelagica, which was 
not only exceedingly abundant in many of the tow-net gatherings, but was represented 
by specimens of large size and great beauty. On the previous expedition this species 
was only met with in the shape of a few dead shells in the bottom dredgings from the 
warm area. 
IV. Arctic Seas. 
The British North-Polar Expedition of 1875-6, under the command of Capt. Sir 
G. S. Nares, and the Austro-Hungarian Expedition of 1872-4, directed by Lieuts. 
Weyprecht and Payer, have put us in the possession of soundings, which, together with 
some material previously worked out by Messrs. Parker and Jones, afford an excellent 
basis for a knowledge of the Arctic Rmzopod-fauna. The results of the examination of 
these various soundings have already been published, so that a summary of their general 
characters is all that is needful in this place. 
British North-Polar Expedition, 1875-6. 1 
Samples of the sea-bottom were brought from twenty-four localities, pertaining to 
three tolerably distinct areas, namely — 1, Baffin’s Bay and Smith Sound ; 2, Hall Basin ; 
and 3, the region north of Robeson Channel. 
1. Baffin's Bay and Smith Sound. Sixteen soundings between lat. 77° 15' and 
79° 45' N., at various depths up to 220 fathoms, but chiefly less than 80 fathoms; the 
material composed of sand and mud, with small rounded stones and fragments of molluscan 
shells. Most of the samples contained a few Ostracoda and some Hiatomacese in addition 
to Foraminifera. The following were the more prominent species of Foraminifera : — 
Cassidulina laevigata and Cassididina crassa, Virgulina schreibersiana, Truncatulina 
lobatida, Pulvinulina Icarsteni, two or three species of Nonionina (notably Nonionina
