FORAMINIFERA OF THE NORTH PACIFIC OCEAN. 7 



Distribution. — Like the foregoing species this is found almost always 

 when Globigerina types are found. It is recorded by Brady in the 

 Challenger Report from the North Pacific; by Bagg from eight 

 Albatross stations off the Hawaiian Islands. I have had material 

 from a great number of stations wherever Globigerina ooze material 

 has occurred. 



This species, while related to G. bulloides, has a much more definite 

 form and the coiling is very even ; the outline from above or below is 

 nearly circular. 



GLOBIGERINA CRETACEA d'Orbigny. 



Globigerina cretacea d'Orbigny, Mem. Soc. Geol. France, ser. 1, vol. 4, 1840, p. 34, 

 pi. 3, figs. 12-14.— H. B. Brady, Rep. Voy. Challenger, Zoology, vol. 9, 1884, 

 p. 596, pi. 82, figs. lOa-c (?).— Bagg, Proc. U. S. Nat. Mus., vol. 34, 1908, 

 p. 153. 



Description. — Test similar in general characters to G. dubia but 

 more compressed, number of chambers larger in each coil, smaller in 

 size. 



Diameter about 0.5 mm. 



Distribution. — In the North Pacific Bagg records this species from 

 three Albatross stations off the Hawaiian Islands, in 572-1,343 

 fathoms. 



While the fossil forms described by d'Orbigny seem to be dis- 

 tinctive, in the recent material there seems to me to be little to 

 separate these two forms.

Description. — Test spiral, regular, consisting of two or three volu- 

 tions, early chambers inflated, subspherical, later chambers much 

 elongated, pointed or otherwise modified at the tip, spreading radially; 

 wall reticulate; aperture opening into the central umbilical opening, 

 or in the elongate chambers making up the larger part of the base of 

 the chamber, the area of attachment being very much reduced. 



Diameter in adults up to 2 mm. 



Distribution. — Bagg records this species from seven stations of the 

 Albatross in the vicinity of the Hawaiian Islands, depths ranging from 

 384 to 1,259 fathoms. I have had material from about the Hawaiian 

 Islands, Nero station 2037 in 55 fathoms, the shallowest, and from
