Test planispiral, compressed, early portions coiled, later chambers 

 uncoiled but obliquely placed, periphery rounded, chambers compara- 

 tively few, only four or five in the uncoiled portion, sutures distinct but 

 slightly depressed ; wall composed of coarse sand grains but smoothly 

 finished, with a yellowish brown cement ; aperture simple at the distal 

 or peripheral end of the chamber in the uncoiled portion ; color yellow- 

 ish brown. 



Length up to 1.50 mm. 



This typical Arctic species occurs in some numbers in our collec- 

 tions from the Alaska region as follows: A-4, A-7, A-13, A-14, A-15. 

 It shows, as usual, considerable variation in the amount of uncoiling. 



Distribution. — Cordova, Alaska, in 2 fms. ; Skagway, in 6 fms. ; at
