TROPICAL PACIFIC FORAMINIFERA OF ALBATROSS 69 



Holotype of variety. — Cushman Coll. No. 14741, from Mokaujar 

 Anchorage, Fiji. 



This variety has also occurred off Levuka, Fiji, in 12 fathoms, and 

 off Nairai, Fiji, 12 fathoms. Somewhat less typical specimens, but 

 probably belonging to this same variety, occurred off Rotonga, 7 

 fathoms, and at Vavau Anchorage, Tonga Islands, 18 fathoms. 



It is close to the species I have described as Nodohacularia antil- 

 larum from the West Indian region. The Pacific specimens, how- 

 ever, uniformly have more and sharper costae, and the earliest cham- 

 bers are more compressed and smaller in comparison with the adult 

 chambers.

Test with the early chambers planispiral, the later ones rectilinear 

 and rapidly increasing in size as added, adult chambers very strongly 

 pyriform, greatest breadth at the base, and thence rather rapidly 

 contracting toward the apertural end, which is expanded into a 

 broad smooth lip; sutures distinct; wall ornamented by a few, 12 

 to 18 usually, high, thin, platelike costae, which terminate in spines 

 at the basal end, those of the later chambers often bifurcating; 

 aperture elliptical, with a very broad lip. Length, 1.5 mm. ; breadth, 

 0.5 mm.; thickness, 0.35 mm. 



Holotype. — Cushman Coll. No. 14743, from Mokaujar Anchorage, 

 Fiji. 



This is probably the same form as that described and figured by 

 Millett in the above reference from the Malay Archipelago. His 

 specimens, however, show a much larger proloculum, and the coiled 

 chambers show practically no compression, while in our speci- 

 mens from Fiji there is a strongly compressed young stage. Later 

 chambers, however, seem to be very close to ours. It may be that 

 his specimens are the megalospheric form, while ours are micro- 

 spheric. This is a fine distinctive species, beautifully ornamented, 

 and so far as the material we have shows, has only occurred off Fiji 

 at Mokaujar Anchorage, and off Levuka in 12 fathoms. It is 

 common at the type locality. 



In the early stages there may be developed short chambers of one- 

 third of a coil in length, which begin to take on the characteristic 

 costse ornamentation before the adult uniserial stage is developed.
