This species has occurred in very typical form in the Philippine 

 material and was one of those laid aside in 1910 for later description. 

 I agree with the authors that this is a very distinct species and the 

 Philippine specimens are very close to the figured specimens of 

 Heron- Allen and Earland. 



Most of the stations at which it is recorded are in warm shallow 

 water, where Calcarina, Alveolina and other shallow-water genera are 

 abundant. 



The species probably has a wide distribution in coral-reef regions 

 in the Indo-Pacific.

Description. — Test large and broad, rhomboid, very much flattened, 

 chambers low and long; wall thick, of rather coarse angular sand 

 grains imbedded in an unusually large amount of light gray cement; 

 aperture consisting of a series of small openings running from the 

 inner margin of the apertural face to the highest point at the distal 

 end of the test, about 20 in number; color gray. 



Length up to 6 mm.; breadth up to 4 mm.; thickness 0.5 mm. 



Type specimen. — Cat. No. 8502, U.S.N.M., from Albatross station, 

 D5567, north of Tawi Tawi, 268 fathoms (495 meters), bottom 

 temperature 52.0° F. (11.1° C). 



This is a very large species, and with its peculiar aperture is of 

 more than usual interest. The whole test is rhomboid, very flattened, 

 the two sides seeming to differ, one being slightly convex, the other 

 slightly concave, the concave side having the sutures more prominent 

 than the other. 



It has occurred elsewhere in the region at station D5576, north 

 of Tawi Tawi, 277 fathoms (506 meters), bottom temperature 53.3° F. 

 (11.8° C).
