Rare specimens occur only at station 5. They are composed of small, 
angular quartz grains, with a whitish cement, and no visible apertures. The 
species is recorded from a very wide range, but there are entirely different 
forms which should be carefully studied. I have recorded a large form from the 
western Atlantic (Bull. 104, U.S. Nat. Mus., pt. 1, 1918, pl. 13, fig. 6; pl. 14, 
figs. 1-3) which may not be this species. It is certainly not like this northern 
form which seems to be typical. The type station is Hougesund, Norway, 
120 fathoms. iy
