Show -J'5- MR. l<\ CHAPMAN 0\ FORAMINIFERA AND [Mar. IS, GAUDRYINA BACCATA Schwasrer. Some very fine specimens of this peculiar and redundant form occur in the lagoon at Cocos Island. It was not met with at all on the seaward face. The previous occurrences were noted mainly from deep water ; and in this connection it may be remarked that it is not uncommon to find certain forms of Foraminifera inhabiting lagoons as well as deep water, but not in intermediate conditions of depth. SPIRILLINA TUBERCULO-LIMBATA 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, S. tuberculata and S. limbata. It was found somewhat sparingly at Cocos Island both inside and outside the lagoon. GYPSINA INH^EREXS Schultze 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 when collected, for they seem to lose it very easily, judging from the rarity of its occurrence. G. inhoerens here prefers the quieter water of the lagoon, but it is also found outside. POLYTREMA MINIACEUM (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 occurrence to the lagoon deposits. 1. 2_ 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 15. 16. 17. Foram in if era from Coco Species.
