FOEAMINIFEKA OF NORTH PACIFIC OCEAN. 



87 



Albatross stations D3375, D3376, 1,132 and 1,201 fathoms. I have 

 examined his material from the latter station, two specimens, each 

 with eight chambers, evidently not complete, but of the typical form. 

 One of these specimens is figured (fig. 120).

Fig. 121.— Reophax 

 dentaliniformis. 

 X 20. 



Description. — Test slender, tapering, composed of a 

 few (five or six) elongated chambers, but slightly tumid 

 in the middle, in a straight or slightly curved line, 

 walls composed of rather coarse sand grains but very 

 neatly cemented together, giving a fairly smooth exte- 

 rior, aperture rather large, at the end of the short tubu- 

 lar neck ; color gray. 



Length up to 2 mm. 



Distribution. — This species is now known from fifteen 

 stations in the North Pacific, down to 3,950 fathoms 

 off Japan. Schlumberger records the species from the 

 Okhotsk Sea and the other stations cover rather well 

 the area south of lat. 40° N. from the coast of Japan 

 to the Hawaiian Islands and off the west coast of Mexico and 

 Central America. 



Goes's specimens from Station D3276, 1,132 fathoms, are for the 

 most part complete and typical. The specimen referred by Bagg to 

 Reophax nodulosus is really a specimen of R. dentaliniformis H. B. 

 Brady.
