TROPICAL PACIFIC FORAMINIFERA OF "ALBATROSS" 31 



fathoms. Our specimens are very typical, and occur at Guam 

 Anchorage, Ladrone Islands, 21 fathoms, and a single specimen from 

 Albatross Station H3866, latitude 17° 17' S., longitude 145° 45' 

 30" W., in 804 fathoms.

Test elliptical or ovate in front view, much compressed, narrowly 

 elliptical in end view, periphery slightly keeled, sides of the test very 

 peculiarly ornamented with a series of fine longitudinal costae in the 

 central portion, from which radiates a series of curved costae forming 

 a distinct border about the central portion; apertural end somewhat 

 extended into a slight neck. Maximum length, 0.45 mm; breadth, 

 0.20 mm; thickness, 0.08 mm. 



This is one of the most beautifully ornamented species of the genus, 

 and is one which is confined to the Indo-Pacific region, although 

 there is a reference for it by Halkyard from the Eocene of Biarritz. 

 All the other records are from the Indo-Pacific. Parker and Jones's 

 types were from Australian coral reefs although they record it also 

 from the Miocene of France. Other records include that of Millett 

 at the Malay Archipelago, where it is recorded as common, from the 

 Southwest Pacific by Sidebottom, rare at Funafuti by Chapman, at 

 several stations in the Kerimba Archipelago by Heron- Allen and 

 Earland, in the Challenger collection by Brady from Nares Harbor, 

 Admiralty Islands, at 37 fathoms, and from Kaine Island, Torres 

 Strait. The species is rare in our collections, occurring off Levuka, 

 Fiji, and at Albatross Station H3993, Schischmarev Pass, Wotje, 

 3 miles N., in 1,187 fathoms.
