Description. — Test planospiral, composed of about two coils, cham- 

 bers very low and broad making a subglobose test, usually three or 

 four chambers making up the last-formed coil, slightly concave at 

 the umbilici, wall coarsely arenaceous, rather rough, thin; aperture

at the base of the apertural face consisting of a short slit which is 

 often obscured by sand grains; color variable, depending largely upon 

 the material composing the test. 



Diameter 0.25-0.75 mm. 



Distribution. — Brady gives but one North Pacific Challenger station 

 for this species, off the Philippines in 2,550 fathoms. The volume 

 on the "Summary of Results" also gives a record off Japan, Chal- 

 lenger station 237 in 1,875 fathoms. 



A number of specimens from Nero station 1295, in 1,415 fathoms 

 between Yokohama and Guam, are possibly this species. Otherwise 

 I have seen no North Pacific material referable to it.

Description. — Test usually planospiral consisting of two or more 

 coils, involute, depressed at the umbilici, chambers very broad and 

 low, wall arenaceous somewhat roughened but variable, chambers 

 usually seven or eight in the last-formed coil, making the test as a 

 whole subglobose, aperture a more or less elongated slit at the base 

 of the apertural face, simple; color gray or brown. 



Diameter 1-2.5 mm. 



Distribution. — As Haplophragmium latidorsatum this species has 

 been widely recorded. There are given eleven Challenger stations in
