TROPICAL PACIFIC FORAMINIFERA OF ALBATROSS 15 



This species was originally described by Bagg from off the 

 Hawaiian Islands. It is now known from numerous stations, espe- 

 cially from the Philippine region and in the North Atlantic. It has 

 proved to be the most common species of the genus in these collec- 

 tions but occurs only in the Albatross material from comparatively 

 deep water as follows: Station H3808, entrance to Avatoru Pass, 

 Rahiroa Atoll, Paumotus, 645 fathoms; H3810, same locality, 661 

 fathoms ; H3959, Ngaruae Pass, Fakarava Atoll, 666 fathoms ; H3860, 

 off Fakarava, 602 fathoms; and H3954, off Nomuka Island, Cook 

 Islands, 600 fathoms. 



The specimens are uniform in showing the peculiar flaky rough- 

 ness, especially over the earlier chambers, obscuring the sutures to a 

 considerable degree.

The peculiar form figured here occurred in Makemo Lagoon, 

 Paumotus. No other specimens were found with this to give the 

 complete characters of the species.

Plate 4, Figures 1 a, b 



Test large, stout, somewhat longer than broad, early triserial 

 portion usually confined to the earliest stages, later becoming biserial 

 for most of the growth, periphery broadly rounded ; chambers fairly 

 distinct, with the lower side much excavated, sometimes with one 

 or more backwardly directed projections overlapping onto the pre- 

 ceding chamber; sutures distinct, depressed, nearly horizontal or 

 somewhat upwardly curved in the middle ; wall arenaceous, but with 

 much cement rather smoothly finished; aperture a low opening at 

 the inner margin of the last-formed chamber. Length, 2 mm.; 

 breadth, 1.35 mm. ; thickness, 0.75 mm. 



Holotype. — Cushman Coll. No. 14698, from Alofi Niue. 



This species has been often recorded from the Indo-Pacific as 

 Tevetularia rugosa (Reuss). The early stages are, however, 

 triserial, and the species should be placed in Gaudryina. This has 

 been noted by Heron-Allen and Earland in their Kerimba paper, 

 and shown by them in figures in that same paper (pi. 47, figs. 7-9). x 



Though the species described by Reuss from the Tertiary from 

 Gaas has apparently chambers that are excavated somewhat at the 

 base, it is certainly not the same as this very large species, so
