Radiolaria of the Arctic Expedition, 1875-76. 429 
label “ brought by Mr. Egerton, April 1876.” It contained 
but few specimens, and these of only four species. Though 
manifestly insufficient to show the extent of the fauna, they 
have been allowed a column in the Table as representatives of 
a region somewhat separated from the rest. Ostracoda were 
present, but in very small numbers. 
T. Winter quarters of the ‘ Alert,’ 1875-6, 6 fathoms, lat. 
82° 27' N. 
Four tubes containing dried mud. Foraminifera chiefly 
of the genera Globigerina, Cassidulina, Nonionina, and Poly- 
stomella. Some of the tubes gave also a few Diatomacez 
(Triceratium arcticum) and occasional valves of Ostracoda. 
U. Mud-beds, 150 feet elevation, lat. 82° 27’ N. 
This material was found to be almost devoid of organic 
remains of any sort; the few specimens of Foraminifera were 
of quite the commonest species. 
V. Floeberg Beach, July 1876, lat. 82° 29' N. 
A small tube of sand from the shore, and a pill-box with 
mud and stones from a depth of 10 fathoms, only furnished 
together what appears to be an incomplete list ; and the speci- 
mens were all very small. There were a few Ostracoda also 
present. 
W. Cane Ravine, June 1876, lat. 82° 33! N. 
A lot of finely divided silt, taken out of a specimen of 
Astarte borealis, from mud-beds 100 feet above the sea-level, in 
Grinnell Land; containing small examples of a few of the 
common arctic types of Foraminifera and Ostracoda. 
X. Sounding, May 11, 1876, 72 fathoms, lat. 83° 19" N. 
The most interesting sounding in the entire collection, not 
merely as being the most northerly, but also, considering the 
minute quantity that could be obtained for examination (only 
a few grains altogether), as presenting the most varied range 
of Microzoa. It consisted of fine soft mud containing Diato- 
macez (Coscinodiscus radiatus), Radiolaria in greater variety 
than any other sounding, and Foraminifera of no less than 
eleven genera, the most abundant of the latter being a dwarf 
variety of Globigerina. 
Tn tracing on the map the area represented by this collec- 
tion, and comparing it with that covered by previous researches, 
it becomes manifest that the ground is altogether new. Our 
present knowledge of arctic Rhizopoda is chiefly derived from 
the labours of Profs. W. K. Parker and T. Rupert Jones, and of 
the Rev. A. M. Norman. The memoir of Messrs. Parker and
