 man Lab. Foram. Res., 1946, p. 19, pi. 3, figs. 39-42. — Cushman and 

 Todd, Special Publ. No. 21, 1947, p. 11, pi. 1, fig. 30. 



Test with the main portion roughly triangular in longitudinal sec- 

 tion, the sides slightly convex and the greatest width near the base ; wall 

 of the middle portion smooth but with a fine granular appearance and 

 nearly opaque ; base with a few raised costae radiating out from the center 

 of the lower face; apertural end with an elongate, tapering neck orna- 

 mented with longitudinal costae, occasionally tending to become slightly 

 spiral. Length 0.30-0.40 mm. ; diameter 0.25-0.28 mm. 



The types of this species are from the Pleistocene of Timms Point, 

 near San Pedro, California. It has also been recorded from off the state 

 of Washington and occurs in typical form in the Hancock collection. 

 A series showing some of the variations is figured. 



Stations: 1, 1006, 1016, 1042, 1143, 1144, 1158, 1159, 1165, 1166, 

 1167, 1168, 1229, 1231, 1233, 1234, 1239, 1240, 2003, 2157, and 2163. 



Distribution. — All but three of these stations are off the Channel 

 Islands with the range in depth being 31 to 105 fms. The average depth 

 is 50 fms. Stations 2003, 2157 and 2163, off the coast of Mexico, are 

 not far distant from the Channel Islands.

 Gray, Special Publ. No. 19, Cushman Lab. Foram. Res., 1946, p. 19, 

 pi. 3, figs. 35-38. 



Variety differing from the typical form in the angled periphery near 

 the base and the costae largely confined to the very basal part. 



The types of this variety are also from Timms Point, near San Pedro, 

 California. Typical specimens occur at these stations. 



Stations: A-1, 1041, 1042, 1129, 1157, and 1167. 



Distribution. — Stations A-1, Ketchikan, Alaska, in 8 fms., again at 

 Monterey Bay, Point Pinos, Point Fermin and San Miguel constitute 

 the range for these studies. The average depth is 28 fms.
