I have specimens from five stations, Albatross station H2922, in 268 

 fathoms, station H3007 in 323 fathoms, Nero stations 2037 in 55 

 fathoms, 2064 in 1,355 fathoms and 2071 in 271 fathoms. All these 

 five stations are close to the Hawaiian Islands. 



These specimens as well as those which have been described by 

 others are not very distinct from B. punctata except in the striations 

 of the early chambers.

Description. — Test elongate, tapering, the apical end occasionally 

 rounded, but usually pointed with one large spine or two or more 

 small ones; chambers comparatively few, inflated; 

 sutures much depressed; wall calcareous, ornamented 

 by longitudinal raised costse, occasionally branching 

 or anastomosing, continued even on the last-formed 

 chamber; aperture broadly oval, subterminal, occa- 

 sionally with a small tooth projecting into the ori- 

 fice, bordered with a raised lip ; color, white. 

 Length 0.50-0.80 mm. 



Distribution. — Brady found this species abundant 

 in material from the II yalonema- ground south of 

 Japan, in 345 fathoms. I have examined material 

 from more than twenty stations, all in the region 

 about Japan or to the southward. At some of these 

 stations specimens are fairly common. The Albatross 

 material from near the southern coast of Japan in 

 most of stations from D4965 to D4975 contained this 

 species. These stations are in the same region as the 

 Challenger station mentioned above. They vary in 

 depth from 191 to 905 fathoms. The species is well 

 represented in the Nero material, mostly from the 

 line of soundings between Guam and Yokohama. In 

 depth these soundings range within the limits just 

 given for the Albatross stations. In the Tuscarora 

 material lately come under notice there is a single 

 mounted specimen from station 2, which is south of 

 the Hawaiian Islands, in 1,468 fathoms. The speci- 

 men is typical in all its characters. 

 The specimen recorded by Doctor Bagg from the vicinity of the 

 Hawaiian Islands proves upon examination to be Bulimina buchiana, 

 d'Orbigny.
