FOKAMINIFEKA OF NORTH PACIFIC OCEAN. 15 



LAGENA AMPUIXA-DISTOMA (Rymer- Jones), var. CRIBROSTOMOIDES, new variety. 



Plate 4, fig. 3. 



Description. — Like the typical, but the aperture a sieve-like plate, 

 with numerous small rounded openings, apical end with numerous 

 spines as well as the apical tubular projection. 



Length 0.4 mm. 



Distribution.— Type-specimen, Cat. No. 8527, U.S.N .M., from Nero 

 station 1310 in 518 fathoms between Guam and Yokohama. 



Thia variety shows a rather unusual type of aperture for this 

 genus. 



LAGENA HYSTRIX Reuss.

 Lagena histrix Terquem, Mem. Soc. Geol. France, ser. 3, vol. 2, 1882, p. 28, pi. 



1 (9), fig. 14; ser. 3, vol. 4, 1886, p. 7, pi. 1, fig. 7. 



Description. — Test flask-shaped, somewhat compressed, broadest 

 at about the middle, neck short; surface with spine-like tubes, open 

 at the end, intermediate spaces punctate. 



Length 0.5 mm. 



Distribution. — Specimens which from their peculiar surface orna- 

 mentation seem to belong to this species occurred off Japan, Nero 

 station 1294 in 1,417 fathoms and Albatross H4878 in 84 fathoms, 

 bottom temperature 51.9° F. 



A figure is given showing the surface view of the tubulations. 

 These are apparently not broken spines, as suggested by Brady, but 

 are a definitely developed surface character in the test of this species. 



LAGENA PUNCTULATA, new species. 

 Plate 5, fig. 4. 



Description. — Test flask-shaped, broadest below the middle, 

 apical end rounded, apertural end gradually tapering to a short neck 

 with a phialine lip; rounded in cross section; surface with an orna- 

 mentation consisting of an irregular series of large punctse or fine 

 pores, with the areas between finely punctate. 



Length 0.4 mm. 



Distribution. — Type-specimen, Cat. No. 8528, U.S.N.M., from Alba- 

 tross station H4878 in 84 fathoms off Japan. 



This species is perhaps related to L. hystrix, but the ornamentation 

 consists of pores instead of spine-like tubulations.
