Test usually less than twice as long as broad, much compressed, great- 

 est breadth formed by the last pair of chambers, periphery serrate or 

 spinose; chambers distinct, numerous, inflated, much broader than high, 

 very slightly overlapping, increasing rather regularly in size as added, the 

 lower peripheral angle in the adult ending in a distinct spine; sutures dis- 

 tinct, depressed, nearly straight, strongly oblique, forming an angle of 

 about 45° with the horizontal; wall smooth, finely perforate; aperture 

 narrow, elongate. Length 0.25 mm. ; breadth 0.20 mm. ; thickness 0.08- 

 0.10 mm. 



Specimens of this species are rather rare in these collections. There 

 seems to be considerable variation, and the specimens on Plate 25, Figs. 

 11, 12, have traces of spines and occur with typically spinose specimens. 

 They are referred here with some question, although they seem definitely 

 related to one another.

Distribution. — Beginning with one record off Redondo, California, 

 in 70 to 240 fms., the series of stations places this species as far southward 

 as Colombia with a depth range from 45 to 116 fms.

 Plate 25, Fig. 13 



Test small, early portion gradually tapering, adult portion with the 

 sides nearly parallel, only slightly compressed ; chambers numerous, dis- 

 tinct, not inflated, very low in the early portion, about as high as broad 

 in the adult; sutures distinct, little if at all depressed, at nearly right 

 angles to the elongate axis ; wall smooth, finely perforate ; aperture elon- 

 gate oval, extending from the base of the last-formed chamber to the 

 middle of the outer apertural end. Length 0.30-0.35 mm.; breadth 0.12 

 mm. ; thickness 0.08 mm.
