about Guam at several Nero stations, 891 to 1,143 fathoms. It 

 occurs usually in but small numbers. 



This is a pelagic species and in the adult with the very large aper- 

 tures it is easily possible for the sarcode to extend out to form the 

 usual vesicles. The tips of the long chambers are pointed, flattened, 

 fimbriate or even sometimes show a tendency toward branching. 



"GLOBIGERINA DUTERTREI d'Orbigny. 



Globigerina dutertrei d'Orbigny, in De la Sagra, Hist. Fis. Pol. Nat. Cuba, 1839, 

 Foraminiferes, p. 95, pi. 4, figs. 19-21. — H. B. Brady, Rep. Voy. Challenger, 

 Zoology, vol. 9, 1884, p. 601, pi. 81, figs. la-c. 



Description. — "Test Kotaliform, suborbicular, both faces convex, 

 margin thick and rounded; composed of about three convolutions, 

 the last of which consists of five segments; segments gradually 

 increasing in size from the commencement, somewhat inflated, espe- 

 cially the later ones; aperture a single arched orifice at the inferior 

 umbilical margin of the final segment. 



"Diameter, gVjth inch (0.5 mm.) or less." 



Distribution. — The only record for this species in the North Pacific 

 is that of Picaglia, who records it from a single station of the Vettor 

 Pisani, long. 109° 58' W.; lat. 0° 47' N., depth 4,670 m. 



I have found no material which seems referable to this rather 

 doubtful species. The description is from Brady.

Description. — Test composed of numerous inflated chambers, 

 usually arranged in a spiral test of about three volutions, the last 

 one composed of four chambers, upper side of test flattened, lower 

 end of chambers prolonged so that in side view the test is about as 

 high as broad; surface reticulate, but usually less conspicuously so 

 than most of the other species of the genus; aperture a long arched 

 opening at the base of the inner face of the chamber. 



Diameter 0.40-0.80 mm.
