THE VOYAGE OF H.M.S. CHALLENGER. 
Station 332.— March 10, 1876. Lat. 37° 29' S., long. 27° 31' W. Depth, 2200 
fathoms ; bottom temperature, 0°’4 C. ; Globigerina ooze. Might with equal 
propriety be termed “ grey mud.” 
The dredged material was rich in Radiolaria, but the Foraminifera were all of 
the common Globigerina ooze species. 
Station 335.— March 16, 1876. Lat. 32° 24' S., long. 13° 5' W. Depth, 1425 
fathoms ; bottom temperature, 2°’3 C. ; Globigerina ooze. 
A somewhat muddy Globigerina ooze, with a considerable number of Ostracoda. 
Contained a large variety of Foraminifera, but comparatively few rare species ; 
amongst the less common may be cited : — Candeina nitida, Spiroloculina 
acutimargo, and Bolivina reticulata. The sandy forms were poorly repre- 
sented. 
Station 337.— March 19, 1876. Lat. 24° 38' S., long. 13° 36' W. Depth, 1240 
fathoms ; bottom temperature, 2° '5 C. ; Globigerina ooze. 
The bottom at this locality and at Station 339 furnished interesting examples 
of what is termed by Mr. Murray “ Pteropod ooze ” (vide, p. 80). The washed 
material consisted chiefly of Pteropod shells ; and the Foraminifera present 
belonged exclusively to surface species. Amongst the latter are most of the 
known forms of Globigerina and of pelagic Pulvinulince, together with a 
considerable number of Hastigerince and Candeina. 
Station 338.— March 21, 1876. Lat. 21° 15' S., long. 14° 2' W. Depth, 1990 
fathoms; bottom temperature, 1 0, 8 C. ; Globigerina ooze. 
A clean Globigerina ooze, with a list of species very similar to No. 335 but 
with a comparative absence of arenaceous types. Candeina nitida, Hasti- 
gerina pelagica, Polymorphina longicollis, Nodosaria calomorpha, and a 
great variety of Lagence, were the most noteworthy Ehizopoda. 
Station 339.— March 23, 1876. Lat. 17° 26' S., long. 13° 52' W. Depth, 1415 
fathoms; bottom temperature, 2° '5 C. ; Globigerina ooze. 
More strictly a Pteropod ooze. Yellow pasty mud, the residue of which after 
washing consisted almost entirely of Pteropod shells and surface Foraminifera. 
Nearly all the known pelagic species were present, including Hastigerina 
pelagica and Candeina nitida. Amongst the bottom forms, the genera Bilo- 
culina, Miliolina Ophthalmidium, Gaudryina, Uvigerina, and Truncatulina 
were best represented. Of the rarer species Spiroloculina acutimargo, 
Ophthalmidium inconstans, Cassidulina calabra, and Truncatulina culter are 
the most interesting. Arenaceous types were conspicuously absent.
