duced, basal end broadly rounded, little if at all extending beyond 

 the previous chamber; aperture rounded with a slightly thickened 

 Up and simple elongate tooth slightly bifid at the tip. 



Length, slightly less than 1 mm. 



Distribution. — Specimens from Tuscarora station 60, in latitude 

 21° 14' N.; longitude 157° 36' W. in 63 fathoms near the Hawaiian 

 Islands seem to belong to this species. 



QUINQUELOCULINA BRADYANA, new species. 



Plate 18, fig. 2. 



Miliolina undosa H. B. Brady (not Quinqueloculina undosa Karrer), Rep. Voy. 

 Cliallenger, Zoology, vol. 9, 1884, p. 176, pi. 6, figs. 6-8. 



Description. — Test stout, usually but slightly longer than broad, 

 chambers angular, more or less plicated laterally, the outer periph- 

 eral angle usually sinuous, the early ones very prominently so; aper- 

 tural end rarely extended to any considerable length, aperture usually 

 narrow with a simple tooth. 



Length, about 1 mm. 



Distribution. — Brady's material was largely from shallow water 

 material of the Indo-Pacific region. The material I have had has all 

 been from comparatively shallow water about the Hawaiian Islands — 

 type specimens, Cat. No. 9160, U. S. N. M., from Nero station 2039 

 in 24 fathoms and another lot from station 2070 in 285 fathoms. 



This species does not seem to be at all identical with the Q. undosa 

 of Karrer described from the Miocene of Austria. Brady himself 

 notes various differences, as do later authors. 



The figured specimen has the apertural end somewhat broken and 

 therefore does not show clearly the complete apertural conditions. 



QUINQUELOCXJLINA UNDULATA d'Orbigny. 



Quinqueloculina undulata d'Orbigny, Ann. Sci. Nat., vol. 7, 1826, p. 302, No. 

 27. — Schlumberger, Mem. Zool. Soc. France, 1893, p. 213, text figs. 23, 24; 

 pi. 1, figs. 53, 54; pi. 2. figs. 60, 61.— Sidebottom, Mem. Proc. Manchester 

 Lit. and Philos. Soc, vol. 48, No. 5, 1904, p. 13. 



Description. — Test irregularly oval in front view, nearly as broad 

 as long, in the young with the chambers very strongly carinate and 

 more or less undulate, sutures indistinct, in the adult becoming more 

 regular; the sutures deeper and distinct, siurface ornamented with 

 rather coarse, slightly oblique, longitudinal striations, the chambers 

 also transversely somewhat wrinkled; apertural end but slightly pro- 

 duced; aperture itself long and narrow with a long tooth, bifid at the 

 tip. 



Length, up to 1 mm. 



Distribution. — The only material which seems to belong to this 

 species is from Nero station 2033 in 249 fathoms off the Hawaiian
