FORAMINIFERA OF NORTH PACIFIC OCEAN. 57 



1145, 1293, 1299, and 1302, between Guam and Japan, with depths, 

 respectively, 2,119, 2,141, 1,817 and 1,331 fathoms. 



At Nero station 1145 a specimen was found, plate 35, figures 6a, o, 

 which may be compared to some of the abnormal specimens, figured 

 by Brady and others. Such forms seem to occur rather frequently 

 in this species. 



NODOSARIA JAPONICA, new species. 

 Plate 28, fig. 4. 



Description. — Test much elongate, large, tapering, composed of 

 numerous cylindrical chambers, sutures of clear material, walls of 

 chambers whitish; apical end often slightly bulbous at the beginning 

 then somewhat contracting before again enlarging as chambers are 

 added; walls smooth, sutures indistinct in outline, but very distinct 

 on account of the difference in texture of the material forming them; 

 last formed chamber in adult specimens often more rounded and 

 distinct, aperture with a tapering neck which is fluted about the 

 opening. ■ 



Length up to 16 mm. 



Distribution. — This species has occurred off japan at Albatross sta- 

 tion D4900 in 139 fathoms, bottom temperature 52.9° F. This seems 

 to be a well-distinguished species. 



Type-specimen. — Cat. No. 8544, U.S.N.M. 



NODOSARIA CATENULATA H. B. Brady. 



Plate 25, fig. 3. 



Nodosaria catenulata H. B. Brady, Rep. Voy. Challenger, Zoology, vol. 9, 1884, 

 p. 515, pi. 63, figs. 32-34.— Flint, Rep. U. S. Nat. Mus., 1897 (1899), p. 312, 

 pi. 58, fig. 2. 



Description. — Test elongate, slender, straight or more often slightly 

 arcuate, tapering; apical end bearing a well-developed spine; cham- 

 bers numerous, elliptical or ovate, distinctly separated by deep 

 sutures ; walls smooth, ornamented by four or six equidistant longi- 

 tudinal costse bridging the depressions between the chambers but 

 usually not continuous over the chambers; costse more or less 

 rounded; aperture small at the end of a long tapering neck, the 

 aperturai end of which is costate giving a stellate appearance in end 

 view. 



Length up to 2 mm. 



Distribution. — Brady described this species from off the Philippine 

 Islands in 95 fathoms. The only other North Pacific record I have 

 for this species is Albatross station H2922 in 268 fathoms off the 

 Hawaiian Islands. Brady records it also from Torres Strait and it 

 is apparently a warm-water species. 



The figured specimen is a young one consisting of but three cham- 

 bers. The view by transmitted light shows the relation of the 

 chambers and the wall.
