Test small, compressed, planispiral, periphery sharply angled, slightly 

 lobulated, consisting of about three coils, involute, but not completely 

 so, the previous coil slightly exposed in the umbilical region; chambers 

 numerous, about 15 in the last-formed coil, triangular in face view, 

 sutures slightly sigmoid, distinct, slightly depressed; wall arenaceous, 

 porous within and showing a tendency to become labyrinthic, surface 

 smooth; aperture a curved slit at the base of the apertural face; color 

 reddish brown. 



Diameter, 0.50-1.50 mm. 



Rather typical material of this small species occurs at localities 227 

 and 2070. 



Distribution. — Both of the station records indicated are located off 

 the Guadalupe Island, Mexico, in 200 to 250 fms.

This species is a very variable one and widely distributed along the 

 eastern shore of the Pacific. The specimens range from very rough to 

 rather smooth, and there is considerable difference in the relative 

 breadth. Our two figures show the extremes.
