Pi .toms, having the same general aspect as those obtained on March 3, 1874, towards 
the Antarctic, but the species were different ; Ithizosolenia was the most abundant. The 
1 »i itoms were sometimes massed together, looking like some of the compound Radiolaria ; 
• Mie jelly -mass observed seemed to be covered with small cylindrical forms, containing 
iinid' of tin- two or three lanceolate or fusiform varieties, which exhibited motions. 
The niii'-o were of a brown-green colour, and were sufficiently numerous to colour the
