Nodosaria subsoluta Cushman, Bull, 104, U. S. Nat. Mus., pt. 4, 

 1923, p. 74, pi. 13, fig. 1. — Norvang, Zoology of Iceland, vol. 2, pt. 2, 

 Foraminifera, 1945, p. 16. 



Test large, elongate, more or less tapering, somewhat arcuate, initial 

 end usually with a short but distinct spine ; chambers few to many, very 

 variable in their separation and increase in size, subglobular or slightly 

 pyriform ; sutures depressed in variable degree ; wall smooth or occasion- 

 ally very slightly costate; aperture terminal, radiate, slightly produced. 

 Length up to 7 mm. 



This species seems to belong really in Dentalina. Specimens show a 

 wide variation as shown in our figures but there seem to be intermediate 

 forms that unite them.

 1246, 2070, and 487. 



Distribution. — Stations 1057 through 1246 are off the Channel Is- 

 lands. They show a depth range of 35 to 490 fms. with the average being 

 111 fms. One record off Mexico, Station 2070, shows 250 fms. and one 

 record. Station 487, off Chatham Island is for 400 fms. Specimens were 

 most abundant off Santa Rosa Island in 56 fms. 



Dentalina hancocki Cushman and McCulloch, new species 

 Plate 41, Fig. 7 



Test elongate, slightly curved, early portion irregularly quadrangular 

 in section with raised angles, later with globular chambers, first with 

 longitudinal costae ending in spinose projections above the basal suture, 

 latest ones smooth; chambers of the early part increasing very slowly 

 in size as added, quadrate, later globular; sutures distinct, earlier ones 

 somewhat curved and not depressed, in the adult strongly depressed and 

 nearly straight; wall with continuous longitudinal costae in the early 

 part, then costae confined to a single chamber and finally smooth ; aper- 

 ture in the adult with an elongate, cylindrical neck with slightly radiate 

 lip. Length of holotype 1.20 mm.; diameter 0.14 mm. 



Holotype (AHF no. 67) from Station 1080. 



This distinctive species is very rare, being represented by a single 

 specimen in our material. 



Station: 1080. 



Distribution. — The type locality. Station 1080, is off San Clemente 

 Island in 150 fms.
