TROPICAL PACIFIC FORAMINLFERA OF ALBATROSS 



55 



Holotype.—U.S.NM. No. 22078, from Albatross Station H3935, 

 1 mile west of Hereheretue Atoll, Paumotus. 



This species, with its large flat tooth and broad, semicircular open- 

 ing with the acutely angled chambers, seems to be a distinct one 

 in fairly deep water among the islands of the South Pacific. There 

 are specimens from Pinaki Atoll and from the beach off the wharf 

 at Hereheretue. It occurs also at a number of Albatross stations, 

 the data for which are given in the accompanying table.

TKILOCULINA OCEANICA, new species, FLINTIANA, new variety 



Plate 12, Figures 4 a-c 



Variety differing from the typical in the ornamentation of the 

 surface, which consists of numerous additional fine costae, especially 

 on the periphery, in addition to the angles of the chambers. 



Holotype of variety.— U.S.N.M. No. 22089, from Albatross Station 

 H3857, one-half mile east of Center Tikei Island, Paumotus. 



This variety is evidently closely allied to the species, but seems 

 to be worth a distinction from the smoother form.
