FORAMINIFERA OF THE PHILIPPINE AND ADJACENT SEAS.

thence gradually narrowing toward the apertural end; wall rather 

 thick, composed of fine material with much cement, smoothly finish- 

 ed; aperture rather small, elliptical; color reddish-brown, lighter 

 about the aperture. 



Length 5 to 10 mm. 



Several specimens of this species were found at D5236, oft' the east 

 coast of Mindanao, 494 fathoms (903 meters), bottom temperature 

 41.2° F. (5°.l C). 



This species is much more elongate in regard to its entirety and 

 in its individual chambers than other species of the genus. Its 

 nearest related species seems to be Hormosina carpenteri H. B. 

 Brady, but the curvature of the test and the shape of the chambers 

 is very different.

Description. — Test elongate, composed of several chambers ar- 

 ranged in an irregular line, pyriform, base rounded, tapering toward 

 the apertural end, increasing slightly in size toward the apertural 

 end of the test; wall composed of fine arenaceous material, often 

 made hispid by included sponge spicules. 



Length up to 12.5 mm. or more. 



Distribution. — The only material I have had of this species was 

 rather characteristic, from Albatross D5259, off northwestern Panay, 

 312 fathoms (571 meters), bottom temperature 49.3° F. (9.6° C).
