,890 MR. F. CHAPMAN ON DEEP-SEA FORAMINIFERA 



pela<2;ic Foraminifera are chiefly represented by OrhuUna universa, Glohi- 

 qerina conglohata, G. triloba, G. sacculifera, Piillenia ohliqidloculata, Pul- 

 vinulina tnenardii, P. tumida, P. crassa, P. canariensis, and P. patagonica. 



Station 11.— July 2nd, 1896. Lat. 16° 20' 0" S., long. 176° 50' 5" E. 

 Depth, 1417 fathoms. Globigerina Ooze. Diy^ pale fawn; wet, pale 

 reddish brown ; coherent. Ostracoda are moderately common, represented 

 by Argilhiecia. (?) Bytliocypris (with a new sp. heterodoxd), .Bairdia, CytJiere 

 (with a new sp. siveeti), Krithe, CytJienira (with a new sp. tenuicosta), and 

 Cytlieropteron. Radiolaria o£ the genus Rliopalastrum. Teeth and otoliths 

 of Fishes. 



Of the Foraminifera the families Miliolidse, Astrorhizidse, Textulariidse, 

 Ltigenidse, Rotaliidse, and Nummulinidse are sparingly represented. The 

 lare Rotalia hroechhimia occurs here. The pelagic Foraminifera form the 

 bulk of the material, the chief of which are Orbulina universa, Globigerina 

 subcretacea, G. saccidifera, G. cequilateralis, G. conglobata, Pidlenia obliqui- 

 locidata, Splicer oidina dehiscens, Candeina ?iitida, Pulvinidina patagonica, and 

 P. truncatidinoides. 



In this sample a piece of pumice of whitish appearance^ measuring about 

 3x2 cm., occurred. 



Station 13,— July 2nd, 1896. Lat. 15° 39' 5" S., long. 177° 3' 0" E. 

 Depth, 1050 fathoms. Globigerina Ooze. Dry, pale fawn ; wet, pale 

 reddish brown ; incoherent. Ostracoda numerous ; the following genera 

 occur : — Aglaia, Pontocypris (with a new sp. davidiana), Argilloecia (with a 

 new sp. gracilior), Bytliocypris (and the new spp. sollasi and lieterodoxa), 

 Bairdia, Cytliere (and the new sp. sioeeti), Kritlie, Loxoconcha, Xestoleberis, 

 Cytlieropteron (and a new var. C. assimile var. fimafutiensis), Bytlio cytliere 

 (and the new sp. retiolata), and Pseudocytliere (with the new sp. funa- 

 futiensis). Hexactinellid Sponge-spicules, Echinoid spines, Pteropods (Sty- 

 liola), and Fish-otoliths. 



This sample is very rich in Foraminifera, miliolid and rotaline forms being 

 especially well represented. The abundant pelagic fauna is chiefly composed 

 of Orbulina universa, Globigerina rubra, G. bulloides, G. saccidifera, G. con- 

 globata, G. triloba, Sphceroidina dehiscens, Ptdlenia obliquilocidata, and Pulvi- 

 7iulina menardii. A noteworthy species occurring in this sample is the 

 beautifully ornate Lagena juddiana. 



Station 19.— July 4th, 1896. Lat. 15° 26' 2" S., long. 177° 17' 0'' E. 

 Depth, 1995 fathoms. Grlobigerina Ooze. Dry, pale fawn ; wet, reddish 

 brown ; coherent. Ostracoda rare, only the usual deep-water form Kritlie 

 tumida occurring here. 



The Foraminifera are not numerous as regards species, but the non-pelagic
