AND OSTRACODA COLLECTED ROUND FUNAFUTI. 439 



SUMMARY OF RESULTS. 



The foregoing report deals with 231 species and varieties o£ Foraminifera 

 and 52 species and varieties of Ostracoda. 



The following new species and varieties are herein described : — 



FORAMINIFERA. 



Siloculina lucernula, Schwager, var. striata, nov. 

 Cassidulina hradii, Norman, var. attenuata, nov. 

 Lagena juddiana, sp. nov. 



Ostracoda. 



Pontocypris davidiana, sp. nov. 

 Argilloecia gracilio7\ sp. nov. 

 Bytliocypris sollasi, sp. nov. 

 (?) „ heterodoxa, sp. nov. 



Cythere curvicostata, G. S. Brady, vslv. funa/utietisis, nov. 



„ sweeti, sp. nov. 

 Cytherura tenuicosta, sp. nov. 



Cytherojyteron assimile, Gr. S. Brady, var. funafutiensis, nov. 

 Bytliocythere retiolata, sp. nov. 



„ tuber culata, sp. nov. 



Pseudocythere funafutiensis, sp. nov. 



Some fossil species of Foraminifera and Ostracoda are here noted as recent 

 for the first time. They are : — 



Virgulina pertusa, Reuss (Pliocene ; Antwerp). 



Lagena ventricosa, Silvestri (Miocene ; Piedmont) ; but that author 



compares them with Brady's recorded " L. apiculata.^^ 

 Loxoconclia latissima, Gr. S. Brady (Pliocene ; Antwerp). 



In relation to the question of the influence of light on the coloration of 

 organisms in the ocean depths, it is interesting to note the occurrence of 

 deeply coloured tests of Polytrema miniaceum at a depth of 507 fathoms. 



A special interest attaches to some of the species found in these samples, 

 on account of the great depth at which they were obtained. Particularly 

 would we notice the forms occurring at depths from 2000 to 2728 fathoms, 

 or from 2;|^ to over 3 miles.
