constituents in the “ Biloculina-ooze”’ of the cold area of the 
North Atlantic) was found, if we except a chance specimen 
or two in No. 518. 
Two species of Ostracoda were noticed, namely :— 
Krithe glacialis, B. C. § R. Cytheropteron arcuatum, B. C. SR. 
H. No. 515. 23rd May, 1873. Franz-Josef Land. Depth 
163 metres (89 fathoms), mud. 
Chiefly reddish siliceous sand, with fragments of Saccam- 
mina-tests. The quantity was too small to yield an extensive 
list of Foraminifera. 
Two species of Ostracoda were found :— 
Cythere mirabilis, Jones. Krithe glacialis, B. C. & R. 
I. No. 515a. 23rd May, 1873. Franz-Josef Land. Depth 
163 metres (89 fathoms), light-coloured mud. 
Very similar to the foregoing, but somewhat richer in the 
smaller Rhizopoda. 
J. No. 516. Ist June, 1873. Franz-Josef Land. Depth 
238 metres (130 fathoms), light-coloured mud. 
Siliceous sand, with fragments of soft brown rock and red 
earth. 
'-The entire quantity of material was less than a gramme ; 
it yielded nevertheless seventeen species of Foraminifera, 
K. No. 518. 4th June, 1873. Franz-Josef Land. Depth 
207 metres (113 fathoms), light-coloured mud. 
Fine clean siliceous sand. One of the richest samples in 
the variety of its Rhizopod-fauna. — 
Contained also specimens of a single species of Ostracoda, 
namely Arithe glacialis, B. C. & R. 
L. No. 5196. 5th June, 1873. Franz-Josef Land. Depth 
198 metres (108 fathoms), dark-coloured mud. 
Siliceous sand, with some brown clay. _ 
Contained very few species, and nothing of much interest. 
M. No 519,a. 6th June, 1873. Franz-Josef Land. Depth 
198 metres (108 fathoms), dark-coloured mud. 
Siliceous sand, with fragments of a brown variety of quartz 
and a good deal of red earth. . 
Like the foregoing, contained only a small number of Fora- 
minifera. Of Ostracoda, Arithe glacialis, B. C. & R., was 
the only species observed.
