782 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 14 



The ovicell is prominent, about 0.40 mm in either direction, the 

 surface finely granulated like the frontal. 



The most characteristic feature is the spout-like peristome and the 

 small secondary aperture, about 0.18 mm wide by 0.12 mm long (though 

 there is considerable variation). It has been recorded positively only 

 from the British Isles at depths from 80 to 205 fms. O'Donoghue listed 

 it somevv^hat doubtfully from Northumberland Channel, British Co- 

 lumbia, at 15 to 18 fms, but as he did not give a full description and 

 mentioned only a few variations this record must remain in doubt until 

 the species is recovered from that area. 



Point Barrow, Alaska, Arctic Research Laboratory, 48 to 80 fms, 

 G. E. MacGinitie, collector, rather common.
