396 Mr. H. B. Brady on some Arctic Foraminifera. 
though the quantity of the material was too small to yield re- 
sults of any great value taken alone, the information it affords 
is of considerable interest in connexion with the still more 
northerly fauna brought to light by the enterprise and perse- 
verance of Lieuts. Weyprecht and Payer. A summary of the 
report, with some slight corrections, is therefore presented 
herewith as a supplementary note, and will be found on a 
later page. 
We may now turn to what is more particularly the subject 
of the present paper—the material procured on the Austro- 
Hungarian expedition. 
The parcel of soundings contained in all sixteen samples 
of the sea-bottom, varying in quantity from 0°15 to 12:0 
grammes, but, for the most part, between one and two grammes 
in weight. ‘Their physical characters and contents are de- 
scribed in general terms in the followmg summary. ‘The 
letters A to P correspond to the headings of the columns of the 
Distribution Table. The depths are given approximately in 
fathoms as well as in metres, for more ready comparison with 
the Tables contained in the memoirs which have been re- 
ferred to. 
A. No.500. 29th July, 1872. Lat. 74°? 46’ N., Long. 53°? 
36’. Depth 400 metres (219 fathoms). 
Fine grey siliceous sand with fragments of slate and occa- 
sional grains of magnetite. In this as well as in some other 
of the soundings there occur little masses of red earth, proba- 
bly the result of the decomposition of some volcanic mineral. 
In sounding 522 (N) the shells of many of the calcareous 
Foraminifera are more or less stained brown by it. 
This sounding is the richest of the whole series in the variety 
of the Foraminifera it contains, thirty-two species in all having 
been found. Of Ostracoda* only a single species was noticed, 
Krithe glacialis, Brady, Crosskey, and Robertson. There 
were also a number of sponge-spicula and fragments of 
Polyzoa. 
B. No. 501. Lat. 74° 48’ N., Long. 54° 53’ EK. Depth 130 
metres (70 fathoms), mud. 
Siliceous sand, with fragments of black shale and of hyper- 
sthene or some similar mineral. The total amount of material 
* The Ostracoda were in all cases reserved when picking out the Fora- 
minifera ; but the number of specimens obtained was too small for sepa- 
rate treatment. My brother, Dr. G. 8S. Brady, has been kind enough to 
to examine them ; and the results are embodied in the present report.
