428 Mi. H. B. Brady on the Reticularia and 
Cassidulina, Pulvinulina, and Nonionina as its prominent 
associates. 
J, K, and L. Dobbin Bay, Aug. 28 to Sept. 1, 1876, lat. 
79° 35! N. 
The column J includes three soundings, namely in 45, 46, 
and 47 fathoms, whilst K and Lare from 113 and 125 fathoms 
respectively. The muddy material obtained in 46 fathoms 
contained the largest number of forms; in that from the 
greatest depth organisms of all sorts are rare. The leading 
types of Foraminifera are Casstdulina, Pulvinulina, and Poly- 
stomella. 
M and N. Off Hayes Point, Aug. 18 and 19, 1876, lat. 
79° 42) N. 
Two soundings, the one in 22, the other in 35 fathoms, _ 
containing a few Diatomacez and Ostracoda and a sprinkling 
only of Rhizopoda, the latter chiefly Cassidulina and Trun- 
catulina, with Virgulina, Pulvinulina, and Polystomella in 
smaller numbers. 
O and P. Off Cape Frazer, Aug. 24th, 1876, lat. 79° 45! N. 
The column marked O is compiled from a single sounding 
at 50 fathoms; that headed P is from three soundings, all at a 
depth of 80 fathoms. The latter taken together yield by 
far the best representative list of the whole series, comprising 
in all thirty-three species of Foraminifera. The most charac- 
teristic amongst them are Polystomella arctica, which is of large 
size and abundant, and the hitherto undescribed type Hyper- 
ammina. Almost all the genera contained in the other lists 
are present to a greater or less extent, the most important 
exception being Polymorphina. 'The same locality also gave 
the richest list of Ostracoda—eleven species, one of which is 
new to science. 
Q. Discovery Bay, lat. 81° 41’ N. 
Comprises two samples—one from 23 fathoms, the other 
from 25 fathoms. Rhizopoda rare and minute, chiefly Cas- 
siduline, other genera being represented by very poor speci- 
mens. 
R. Fiord Valley, near Lincoln Bay, lat. 82° 8' N. 
Mud taken from between the valves of shells ; yielded little 
beyond Cassiduline and the weak varieties of Polystomella. 
The Ostracoda were of more importance and embraced one 
new species. 
S. Mud from ravine north of Repulse Bay, lat. 82° 10’ N. 
A little sandy glacial mud from Hall’s Land, with the
