v.— REPORT ON SAMPLE OF GLOBIGERIXA OOZE. 



Date, 13th July, 1909. Position, 4-- 17 S.. 148.51 E. 

 Depth, 1 122 fathoms (bottom sample). 



Details. — Globigerina Ooze. Colour, pale green, with a 

 slififht grreenish tinge. 



Carbonate ok Li.me. 



Residue. 



Note o\ the Sample. 



This is a fairly typical CAoh'igcrina ooze, with a large per- 

 centage of residue insoluble in HCl, owing to the abundance 

 of silicious sponge-remains. This occurrence of sponge- 

 spicules would naturally lead one to conclude that some of the 

 arenaceous foraminifera which form their tests of these 

 silicious needles would be present, and in this we are not 

 disappointed. Both TechniteUa and Marsipella occur here, 

 and the locality is new for both genera. TechniteUa legumen 

 was previously recorded off Sydney and near Kerguelen Island. 

 T. raplianus is an exceedingly rare form, having been hitherto 

 obtained from only one locality, \'iz., off K.anda\u, Fiji
