Reophax horrida Cushman, Proc. U. S. Nat. Mus., vol. 42, 1912, p. 229, pi. 28, 

 figs. 3, 4. 



Description. — Test elongate, of several chambers, with a nearly 

 straight axis, chambers gradually increasing in size; wall arenaceous, 

 with an abundance of included sponge spicules so arranged as to give 

 a bristly appearance to the exterior of the test; aperture terminal, 

 with a well-developed neck. 



Length about 3 mm. 



This species occurred at D5582, vicinity of Darvel Bay, Borneo, 

 890 fathoms (1,628 meters), bottom temperature 38.3° F., (3.4° C), 

 and D5630, south of Patiente Strait, 569 fathoms (1,081 meters). 



This species differs from others described in the character of the 

 wall, the great number of included spicules bristling in all directions 

 giving a spiny appearance to the wall. 



Reophax horridus — Material examined.

Reophax agglutinatus Cushman, Proc. U. S. Nat. Mus., vol. 44, 1913, p. 637, pi. 

 79, fig. 6. 



Vescri'ption. — Test large and stout, composed of several chambers, 

 nearly globular or slightly pyriform; wall composed almost entirely 

 of aggultinated foraminiferal tests of Globigerina and Pulvinulina, 

 held together by a light grayish cement; aperture with a slightly 

 protuberant neck. 



Length about 6 mm. 



This species was described from Albatross station D5377, in 400 

 fathoms (732 meters), off Marinduque Island. 



This is a large species and peculiar in its agglutinated test, made 

 up almost entirely of other foraminiferal tests. In this respect it 

 resembles R. hilocularis Flint, but is a typical uniserial Reophax. 



It has also occurred at the following stations: D5201, Sogod Bay, 

 southern Leyte, 554 fathoms (1,012 meters); D5259, off north- 

 western Panay, 312 fathoms (571 meters); and D5582, Darvel Bay, 

 Borneo, 890 fathoms (1,628 meters).
