Station 2.— May 20th, 1896. Latitude 11^ 5' 0" S., longitude 178° 40' 0" E. 

 Depth, 1489 fathoms. Globigerina Ooze. -Dry, of a pale fawn-colour ; 

 wet, pale reddish brown ; somewhat incoherent. A few valves of Ostracoda 

 present, belonging to the genera Argilloecia, Bairdia, and Kritlie. Also 

 some Radiolaria of the following genera : — -Mhopalastrum and Hymeniastrum. 

 With the exception of a solitary specimen of Biloculina depressa, a Textularia^ 

 and a few hyaline forms, the bulk of this sample is composed of pelagic 

 Foraminifera, chiefly of the following species : — Globigerina conglobata,. 

 G. saccidifera, G. rubra, PuUenia obliquilocidata, and Pulvimdina menardii. 



Station 3.— May 21st, 1896. Lat. 10° 12' 53" S., long. 178° 52' 0" E„ 

 Depth, 2715 fathoms. Grlobigerina Ooze. Dry, pale fawn ; wet, slightly 

 darker ; incoherent. Ostracoda rare : the genera are represented by Argil- 

 Icecia, Cythere, Krithe, and Xestoleberis. Also some Radiolaria of the 

 following genera : — Cenosphcera. Rhopalastrum, Hymeniastruin, and Echinoid 

 spines. 



The foraminiferal fauna is exceptionally rich in species. Of the porce!- 

 lanous forms the deep-water species Biloculina depressa and its variety 

 murrhyna, and also Miliolina venusta, are conspicuous. The textularids are 

 fairly well represented, and the rare Ehrenbergina hystrhv, occurs here. The 

 family Lagenidse is represented by twelve species of the type-genus Lagena ; 

 whilst the subfamily Polymorphininse appears in the genera Polymorphina 

 and Uvigerina. Besides a few rottiline forms, the bulk of the material is 

 composed of pelagic Foraminifera, as Orbidina imiversa, Globigerina conglo- 

 bata, G. cequilateralis, PuUenia obliquilocnlata, and Pulvimdina menardii. 



Station 4.— May 21st, 1896. Lat. S" b2' 0" S., long. 179° 11' 30" E. 

 Depth, 2728 fathoms. Globigerina Ooze. Dry, pale yellowish brown ; wet, 

 reddish brown ; a sticky calcareous mud. No Ostracoda were noted in 

 this sample. Radiolaria (Hymeniastrwn) and Alcyonarian spicules occur. 

 Echinoid spines are fairly numerous, also Fish-teeth. Foraminifera other 

 than pelagic not common, the most interesting being the curious deep-water 

 species Pidvinulina favus. The most abundant species are Globigerina 

 btdloides, G. diitertrei, G. triloba, G. subcretacea, PuUenia obliquilocidata,. 

 Truncatulina pygmcea, Pidvinulina tumida, and P. exigua. 



Station 10.— June 25th, 1896. Lat. 15° 31' 6" 8., long. 177° 31' 2" E. 

 Depth, 1485 fathoms. Globigerina Ooze. Dry, pale fawn ; wet, pale 

 reddish brown ; coherent. Ostracoda frequent, generically represented by 

 Pontocypris, Bairdia, Cythere (with a new sp., C. sweeti), and Krithe. 

 Radiolaria (Rhopalastrum). also occur. Of the Foraminifera, besides the 

 pelagic forms, the commonest genera are Lagena and Truncatulina. The
