Description. — Test plano-convex, compressed, dorsal side slightly 

 convex, ventral side flat or somewhat concave, umbilicate ; peripheral 

 margin thin, slightly lobulated, carinate; chambers usually six in the 

 last-formed coil; sutures somewhat depressed, especially below, on the 

 dorsal side limbate and curved, ventrally simply depressed, straight, 

 in a radial position; wall usually smooth and punctate but sometimes 

 slightly granular; aperture a rather well-developed opening at the 

 umbilical end of the chamber, with a projecting valvular lip. 



Diameter up to 1.27 mm. 



Distribution. — This species of world-wide distribution is not uncom- 

 mon in the North Pacific. Goes records its being taken in a pelagic 

 condition. Picaglia records it at three stations of the Vettor Pisani 

 just north of the Equator. Bagg records it at 18 out of the 19 

 Albatross stations from which he had material in the vicinity of the 

 Hawaiian Islands, depths ranging from 104 to 1,544 fathoms. I have 

 records of its occurrence at a hundred or more Albatross, Alert, Nero, 

 and Tuscarora stations in the area, and this could have been multi- 

 plied several times but it was thought not worth while to record 

 further. It is common in the North Pacific wherever conditions of 

 depth and temperature are right for the formation of Globigerina ooze.

Description. — Variety differing from the typical in the smaller size 

 and spinose character of the peripheral keel. 



Distribution. — Bagg records this variety from three Albatross sta- 

 tions in the vicinity of the Hawaiian Islands, depths from 3S4 to 1,307 

 fathoms. I have seen a few rather poorly representative specimens 

 from this same region, but there does not appear to be as good a devel- 

 opment of the variety as occurs in the Gulf of Mexico for example.
