TROPICAL PACIFIC FORAMESTIFERA OF "ALBATROSS"

toward the apertural end, where height and breadth are often about 

 equal; sutures distinct, shghtly Hmbate, obhquely curved, forming an 

 angle of about 30°-40° with the horizontal, slightly depressed in the 

 adult portion; wall finely perforate, smooth, except for the early 

 portion, which has numerous, fine, longitudinal costae, sometimes 

 running up halfway of the length of the test; aperture elongate, nar- 

 row at the base, and somewhat expanded at the upper end. Length, 

 0.35 mm.; breadth, 0.10 mm.; thickness, 0.03-0.04 mm. 



This species has previously been known only from the Atlantic, but 

 typical specimens occur commonly at Vavau Anchorage, Tonga 

 Island; in Niau Lagoon and off Niau; 12 fathoms off Nairai, Fiji; and 

 slightly less common inside the lagoon at Pinaki Atoll. There is a 

 single record for it in the Albatross material at station H3915, Pinaki 

 Atoll, 3.5 miles southeast, in 860 fathoms, 37.0° F., glob. maug.

Test small, in front view rhomboid, thickest along the median line 

 and with sharp edges; chambers numbermg about fourteen in the 

 megalospheric form, but more in the microspheric form, much longer 

 than wide, slightly inflated in the later portion of the test; sutures 

 distinct, limbate, sinuous, with processes of varying length on the
