Description. — Test free, rounded, ovoid or irregular in sliape, 

 consisting of a single chamber without divisions of any kind; wall of 

 variable thickness, loosely cemented, consisting of fine white sand 

 or amorphous material, interior smooth, rounded; exterior roughened 

 by numerous protuberant points and ridges; no visible aperture; 

 color whitish or grayish brown. 



Diameter, up to 3 mm., usually less. 



Distribution. — No well characterized material of this species was 

 dredged by the CJiallenger, according to Brady, who records the 

 following stations: Coast of Norway, Bukkenfiord, 365 fathoms 

 (Schulze); Kors Fiord, 180 fathoms (Norman); Faroe Channel, 530 

 fathoms (Murray); and Bay of Biscay (Norman). A poor specimen 

 possibly referable to this species was obtained by the Challenger 

 from station 323, in 1,900 fathoms, in the South Atlantic. 



Flint records the species from Albatross D2385, in 730 fathoms, in 

 the Gulf of Mexico. 



In the material I have had it has been very scarce, the following 

 stations only havmg given it: D2174 in 1,594 fathoms, D2208 in 

 1,178 fathoms, and D2716 in 1,631 fathoms, all southwestward of 

 Georges Banks, and D2399 in 196 fathoms and D2385 in 730 fathoms, 

 both in the Gulf of Mexico. 



STORTHOSPHAERA ELONGATA, new species. 



Plate 18, figs. 1, 2; plate 19, fig. 1. 



Description. — Test free, elongate, in the longest specimens more 

 than twice as long as wide, consisting of a single undivided cavity.
