QUINQUELOCULINA PYGMAEA Reuss. 



Quinqueloculina pygmaea Reuss, Denkschr. Akad. Wien, vol. 1, 1850, p. 384, 



pi. 50, figs. 3a, 6. 

 Miliolina pygmaea H. B. Brady, Rep. Voy. Challenger, Zoology, vol. 9, 1884, 



p. 163, pi. 113, figs. 16, a, b. 



Distribution. — To this species Brady refers specimens from the 

 North Pacific from Hongkong Harbor and south of Japan. 



QUINQUELOCULINA FEROX (Rhumbler). 



Plate 17, figs. 5-7. 



Miliolina ferox Rhumbler, Zool. Jahrb., Abteil. Syst., vol. 24, 1907, p. 47, pi. 3, 

 figs. 29-31. 



Description. — Test generally oval, quinqueloculine, generally 

 smooth, sometimes with a tendency to longitudinal striations; aper- 

 ture elongate, slit-like, narrow, tooth longitudinally more or less 

 split up into distinct tooth-like projections. 



Length, 0.6 to 0.9 mm. 



Distribution. — Rhumbler described this species from shore sand of 

 Laysan where it was frequent. 



Typically the projections of the tooth are distinct at the tip as 

 in figure 6, or occasionally they are united again above leaving a 

 series of openings. 



QUINQUELOCULINA SPIRALIS, new species. 



Plate 20, fig. 1. 



Description.— Test elongate, twice as long as broad, quinquelocu- 

 line, chambers long and narrow, sutures distinct, peripheral margin 

 bluntly angled, occasionally dividing into two blunt carinae with a 

 peripheral depression; wall smooth; whole test twisted about the 

 longitudinal axis, the chambers each making about a half turn; 

 apertural end somewhat extended, especially on the peripheral edge, 

 but only a slight contraction produced; aperture long and narrow 

 with a straight simple tooth nearly the length of the aperture. 



Length, 0.60 mm. 



Distribution. — Type-specimen (Cat. No. 9161, U.S.N.M.) from Nero 

 station 1466 in 234 fathoms off Guam. 



This is a rather striking species in its spirally twisted contour, 

 reminding one somewhat of certain of Terquem's, fossil species from 

 Europe.
