F. CHAPMAN OX FORAMIKIFERA AXD [Mar. 18, 



Gaudryixa baccata Sclivvager. 



Some very fine specimens of this peculiar and rerlundant form 

 occur in the lagoon at Cocos Island. It was not met with at all 

 on the seaward face. The previous occurrences were noted mainlv 

 from deep water ; and in tlais connection it may be remarked that 

 it is not uncommon to find certain forms of Foraminifera in- 

 habiting lagoons as well as deep water, but not in intermediate 

 conditions of depth. 



Spirillina tuberculo- limb ATA Chapman. 



This is a form lately found at Funafuti, which is of peculiar 

 interest on account of its characters partaking of two of Brady's 

 species, namely, aS*. tuherculata and *S'. linibata. It was found 

 somewhat sparingly at Cocos Island both inside and outside the 

 lagoon. 



Gypsixa INH.EREXS Scliultze sp. 



The specimens of the above form from Cocos Island are 

 remarkable for their deep rose-colour, derived presumably from 

 the sarcode of the animal. This colour was a distinctive feature 

 of Schultze's original specimens. The fact of the test being so 

 strongly tinted points to their fresh condition Avhen collected, for 

 they seem to lose it very easily, judging from the rarity of its 

 occurrence. G. inhcerens here prefers the quieter water of the 

 lagoon, but it is also found outside. 



PoLYTREMA MixiACEUM (Pallas), var. ALBA Carter. 



A noteworthy feature of these gatherings was the extraordinary 

 abundance of the white variety of the well-known Polytrema 

 ■miniaceum. It seems restricted in its occuirence to the lagoon 

 deposits.
