Distribution . — Brady records this species from 12 Challenger sta- 

 tions in the North Pacific. Flint * records the species or at least 

 the genus from Nero station 11 in 1,983 fathoms between the Hawaiian 

 Islands and Midway Island and 166-174, 1,593-2,111 fathoms 

 between Midway Island and Guam. Bagg does not record it 

 from the region of the Hawaiian Islands; and in all the material I 

 have examined I have failed to find specimens, whether from lack of 

 care in searching the material or too rough handling in washing the 

 material, or what, I do not know. 



The species may be distinguished from Globigerina sequilateralis 

 which it somewhat resembles in contour by the thinner wall and the 

 peculiar spinose character of the surface. 



Hastigerina pelagica is truly pelagic, and in the specimens obtained 

 in a living condition by the Challenger the sarcode was expanded in 

 the bubblelike form seen in different members of the pelagic group 

 of Foraminifera. 



Genus CANDEINA d'Orbigny, 1839. 



Candeina d'Orbigny (type, Candeina nitida d'Orbigny), in De la Sagra, Hist. 

 Fis. Pol. Nat. Cuba, 1839, Foraminiferes, p. 107.— H. B. Brady, Rep. Voy. 

 Challenger, Zoology, vol. 9, 1884, p. 622. 



Description. — Test usually in the form of an elevated spire, but 

 may be more or less compressed, chambers several, increasing in size 

 as added, globular or subglobular; wall usually clear, finely per- 

 forate, translucent; apertures numerous, elliptical in form along the 

 sutural lines between the chambers. 



This genus is unique in the family in the manner of its develop- 

 ment of numerous apertural openings along the border of the last 

 formed chamber where it comes in contact with the preceding cham- 

 bers. It is represented in the North Pacific material by the follow- 

 ing species : 



CANDEINA NITIDA d'Orbigny.
