 Dentalina filiformis Parker, Jones, and H. B. Brady, Ann. Mag. Nat. Hist., 



ser. 4, vol. 8, 1871, p. 156, pi. 9, fig. 48. 



Description. — Test elongate, slender, arcuate, chambers numerous, 

 elliptical or ovate, elongate, tumid, sutures usually oblique, cham- 

 bers increasing in length toward the apertural end, aperture radiate, 

 slightly eccentric; wall smooth. 



Length up to 5 mm. 



Distribution. — Brady in the Challenger report mentions this spe- 

 cies as being found in the North Pacific, but stations are not given. 

 I have had material from the following stations: Albatross D3608 in 

 276 fathoms; material from stomachs of holothurians, D4900, in 139 

 fathoms off Japan; Nero station 1466, near Guam, in 234 fathoms; and 

 Tuscarora station 11, in 437 fathoms, Iat. 33° 46' N.; long. 140° 21' E. 



Specimens are easily broken and complete specimens seem to be 

 rare.

63, fig. 1.— Flint, Rep. U. S. Nat. Mus., 1897 (1899), p. 310, pi. 56, fig. 5. 



Description. — Test elongate, somewhat arcuate, comparatively 

 stout, composed of few chambers, early ones with little inflation, later 

 ones somewhat inflated, apical end rounded, sutures oblique, wall 

 smooth. 



Length up to 4.5 mm. 



Distribution. — Bagg records this species from one Albatross station 

 off the Hawaiian Islands, H4566, in 572 fathoms. I have had mate- 

 rial from three Nero stations, 10, near the Hawaiian Islands, in 2,098 

 fathoms; 201, near Midway Islands, in 1,033 fathoms; and 990, near 

 Guam, in 859 fathoms. 



The species is not well distinguished from N. communis and seems 

 to be intermediate between this and N. mucronata.
