POLYMORPHINA ANGUSTA Egger. 



Plate 39, fig. 6. 



Polymorphina (Globulina) angusta Egger, Neues Jahrb. fiir Min., 1857, p. 290, pi. 

 13, figs. 13-15.— H. B. Brady, Rep. Voy. Challenger, Zoology, vol. 9, 1884, 

 p. 563, pi. 72, figs. 1-3. 



Description. — Test elongate, compressed, cylindrical, apical end 

 acute and subacute, apertural end obtuse, chambers comparatively 

 few, elongate, sutures but very slightly depressed; wall smooth, 

 aperture finely radiate. 



Length 0.6 to 0.8 mm. 



Distribution. — Brady records this species from one Challenger station 

 in the North Pacific, station 241, in 2,300 fathoms. Bagg also 

 records it in another, Hawaiian Islands, Albatross D4017, in 305 

 fathoms. Bagg's specimen which I have examined seems more like 

 a Quinqueloculina than a Polymorphina, but it is too poor to make out 

 surely. I have had specimens from three Nero stations, 170, north- 

 west of the Hawaiian Islands toward Midway Island, 1,990 fathoms; 

 station 1300 in 1,088 fathoms, and 1301 in 1,529 fathoms, both south 

 of Japan. 



POLYMORPHINA LANCEOLATA Reuss. 



Plate 40, fig. 2. 



Polymorphina lanceolata Reuss, Zeitschr. d. deutsch. geol. Ges., vol. 3, 1851, p. 83, 

 pi. 6, fig. 50; Sitz. kais. Akad. Wiss. Wien, vol. 62, 1870, p. 487, No. 12.— 

 H. B. Brady, Rep. Voy . Challenger, Zoology, vol. 9, 1884, p. 564, pi. 72, figs. 5-6. 



Polymorphina fusiformis H. B. Brady, Parker, and Jones (part), Trans. Linn. 

 Soc. London, vol. 27, 1870, p. 219, pi. 39, figs. 56, c. 



Description. — Test elongate, compressed, cylindrical, fusiform, ini- 

 tial end rather acute, apertural end obtusely pointed; chambers sev- 

 eral, smooth, elongate, tumid, sutures somewhat depressed, last 

 formed chamber rather more inflated; wall smooth. 



Length 1 to 1.25 mm. 



Distribution. — This species has not previously been recorded for 

 the North Pacific. Material referable here has been obtained at 

 several Nero stations between Guam and Japan, depths between 

 1,529 and 2,119 fathoms. The species is not well distinguished from 

 Polymorphina rotundata, differing especially in the more elongate 

 form and less tapering outline.
