REPOET ON THE FORAMINIFERA. 
105 
but with few of the rarer species. This is the most southerly Station at 
which Pulvinulina favus has been found. Lagena seminiformis and 
Cassidulina bradyi are perhaps the most noteworthy species. Amongst 
the microzoa were a good many Ostracoda and some Radiolaria. 
Station 304. — December 31, 1875. Lat. 46° 53' S., long. 75° 11' W. Gulf 
of Penas, west coast of Patagonia. Sounding ; depth, 45 fathoms ; sand. 
Clean, dark-coloured, fine sand, with a poor, starved Rhizopod-fauna. Small 
specimens of Pulvinulina Jcarsteni, a form most at home in the Arctic seas, 
here make their appearance, together with Cassidulina parkeriana, Cassidu- 
lina crassa, and Discorbina vilardeboana. 
Station 305. — January 1, 1876. Lat. 47° 48' S., long. 74^ 48' W. Sounding; 
depth, 120 fathoms ; mud. 
This material also presented a sub-arctic list of Foraminifera, and, without 
information as to the locality might have been supposed to have been 
dredged on the coast of Norway. The conspicuous forms were Truncatulina 
refidgens and Truncatulina lobcitula, Pulvinidina punctidata and Pulvimdina 
karsteni, with various species of Lagena , Uvigerina, Nonionina, Bulimina, 
and Cassidulina. Ehrenbergina pupa was perhaps the most notable species 
met with in its examination. 
Station 306. — January 2, 1876. Lat. 48° 18' S., long. 74° 33' W. Off 
Middle Island. Sounding ; depth, 345 fathoms ; bottom temperature, 7°‘6 C.; 
mud. 
Station 306 A. — Same date. In a neighbouring locality. Sounding ; depth, 
565 fathoms ; mud. 
The soundings from both these points yielded Foraminifera of the same boreal 
character as the foregoing, the genera Bulimina and Nonionina being 
especially prominent. 
Station 307. — January 4, 1876. Lat. 49° 24' S., long. 74° 23' W. Sounding; 
depth, 147 fathoms ; bottom temperature, 7° '6 C.; mud. 
Station 308. — January 5, 1876. Lat. 50° 10' S., long. 74° 42' W. Sounding; 
depth, 175 fathoms ; mud. 
Station 309.— January 8, 1876. Lat. 50° 56' S., long. 74° 15' W. Sounding; 
depth, 40 to 140 fathoms ; mud.
