Description. — Test free, elongate, early portion closely coiled, 

 planospiral, of one or more volutions, each with five to seven cham- 

 bers, later portion uncoiled, made up of a linear 

 series of chambers, in adult specimens making 

 up the larger portion of the test, wall rather 

 coarsely arenaceous, variable in its surface, some- 

 times fairly smooth, sometimes rough; aperture 

 in the early chambers ■ at the base of the aper- 

 tural face, but in the uncoiled portion in the mid- 

 dle of the terminal face, single, circular; color 

 very variable from light to dark gray or brown. 



Diameter of coiled portion about 1 mm. r total 

 length up to 3 mm. 



Distribution. — Brad} r records this species from FlG . hg.^ammobaculites

ing the depths as 7-3,125 fathoms. 1 am unable 

 to find a record giving the shallowest station, but the other four range 

 as follows: 2,050, 2,300, 2,900, and 3,125 fathoms, showing that it 

 occurred as a rule in deep water. Bagg records the species from one 

 station near the Hawaiian Islands, Albatross D4174, in 735-865 

 fathoms. I have found specimens of this species from six North 

 Pacific stations. Single specimens were obtained from three Alba- 

 tross stations near the Hawaiian Islands — H2764 in 122 fathoms, 

 H2999 in 549 fathoms, and II3009 in 603 fathoms. It was obtained 

 in material taken from the stomachs of Holothurians dredged at 

 Albatross station D3603, 1,771 fathoms in Bering Sea, and at two 

 Nero stations — 1308 in 1,040 fathoms and 1410 in 1,144 fathoms — 

 between Yokohama and Guam.
