Description. — Test subspherical, sometimes compressed laterally, 

 composed of numerous chambers, making three or four volutions, 

 each consisting of four chambers, entirely embracing so that the last 

 volution only is visible from the exterior; surface of the test smooth; 

 wall very finely but indistinctly perforate; aperture a narrow semi- 

 circular curved slit near the base of the ventral face of the last-formed 

 chamber and the previously formed volution. 



Diameter usually less than 0.50 mm. 



Distribution. — This is a rare species in the western Atlantic collec- 

 tions. The small size makes it easily overlooked, although it as a rule 

 occurs in the " fioatings '' if at all. The few stations in the accompany- 

 ing table representing the Albatross records show that it has usually 

 occurred as single specimens in the material examined. The only 

 station at which it occurred in any numbers is in cold water, and as 

 this is not known as a pelagic species nor does it show any special 

 adaptations for pelagic life, it may be inferi'ed that it is most at home 

 in deep and cold waters. The desirability of placing this species and 

 the following one with P. obliquilocidafa seems very questionable.
