BULLETIN 104, UNITED STATES NATIONAL MUSEUM. 



Descrijjtion. — Test elongate, usually straight, composed of several 

 (3-8) chambers usually in a straight line, the earlier ones especially, 

 pyriform with a truncate base, well separated from one another by 

 the slender necks, anterior end tapering; wall of rather coarse sand 

 grains firmly cemented but with a rough exterior; aperture circular 

 at the end of a short cylindrical tapering neck; color yellowish brown. 



Length up to 1.6 mm. 



Distribution. — Brady records this species from the Faroe Channel in 

 540 fathoms (987 meters) and from three CJiallenger stations in mid- 

 Atlantic, west of the Azores 1,675 fathoms (3,063 meters), a single doubt- 

 ful specimen off Palma, Canaries, 1,125 fathoms (2,057 meters) and very 

 typical material from the South Atlantic east of Buenos Aires in 1,900 

 fathoms (3,475 meters). Goes records it from Spitzbergen. 



In the Albatross dredgings I have had material from seven stations 

 off the northeastern coast of the United States between latitude 37° 

 and 40° N., and longitude 69° and 74° W. The material from two 

 of these stations is very fine but is small and resembles very closely 

 the figures given by Goes from off Spitzbergen. Except at one 

 station the species is very rare. 



It is also known from the North Pacific in deep water. 

 Reophax guUifer — -material examined.

Description. — ^Differs from the type in the wall of the test which 

 has numerous sponge spicules. 



Rhumbler records but two specimens and these but end chambers. 

 They were from near St. Vincent, Cape Verde Islands, in 659 fathoms 

 (1,205 meters).

Description. — Test large, of few chambers (3-4), each nearly spher- 

 ical and much larger than the preceding, wall very firmly cemented, 

 of coarse angular sand grains, surface roughened by large angular 

 fragments attached to the exterior; chambers distinct, sutures de-
