FORAMINIFERA— HERON-ALLEN AND EARLAND. 47 



from the " Terra Nova " material. Residues largely sponge-spicules, but immature 

 Foraminifera were present in some numbers and diatoms in lesser proportion. 

 Much angular mineral matter. 



• No. 6. Station 96. Augusts, 1911. 7 miles E. of North Cape, New Zealand, 

 70 fms. 



Material— Five samples, 96, 96a, 96b, 96c, 96d. 



Sample 96, in spirit, MoUuscan and sponge-deljris. Foraminifera infrequent 

 but varied. 



Sample 96a, in spirit, coarse shell-sand, Polyzoan debris, angular sand. 

 Foraminifera varied and in fine condition, but not abundant. Many of the shells 

 encrusted with the diatom Navicula (Cocconeis) glacialis, Cleve, a species common 

 to both Arctic and Antarctic material. 



Sample 96b, dry, several lumps of a white-grey limestone of organic origin, 

 similar in appearance and origin to samples 91a and 90b. 



Sample 96c, in spirit and formalin, organic debris of every kuid, including 

 many large specimens of Polytrema, and a little mud. 



Sample 96d, in formalin, fragmentary animal remains with some muddy 

 sand and much flocculent organic matter, very difficult to clean. Sieves yielded 

 a few large Foraminifera and abundant and varied smaller forms. 



Owing to the considerable quantity of material received it was possible to 

 work out the fauna of this Station very completely. It yielded a very large ■ 

 number of species, including several new to science, also many of great rarity 

 and interest. Notable species : — Cornuspira diffusa, Iridia diajjhmia, Detidronina 

 arborescens, IK Umoya, JTyperammina novae-zealandiae, JacideUa acuta, Reophax 

 spiridifcra, B. euneta, Nouria pohjmorpliinoides, Hormosina globulifera, Hastigerina 

 pelagica, Anomulina coronata, Carpenteria proteiformis. Residues : — Sponge-spicules, 

 immature and broken Foraminifera and angular mineral grains. The residues of 

 the fossil sample 96b (as with the other fossil samples) were very scanty, almost 

 entirely calcareous debris and innnatm-e Foraminifera, with hardly any siliceous 

 organisms or mineral grains. These facts point to a change in the conditions 

 under which the deposits were laid down as compared with existing conditions, 

 although the Foraminiferal faunas are largely identical. 



No. 7. No Station number. [Label : — Sounding samples off the East Coast 

 of New Zealand, Oct., 1911.] 



Material. — Soundings in formalin. No details of depth or locality. Differen- 

 tiated into Samples A and B. 



Samph A. — Two tubes of greenish-grey sandy mud. dried light grey and weighed 

 about ^ ounce. Broke down readily in water. 'Sieves contained Globigerina, pumice and 

 angular minerals. Notable species : — Bulimina rostrata. Residues, angidar minerals, 

 foraminiferal debris, manv diatoms, a few coccoliths. No Radiolaria were observed.
