LAGENA HISPIDULA, new species. 



Plate 5, figs. 2, 3. 



Lagena Isevis H. B. Beady (part) (not L. Isevis (Montagu)), Rep. Voy. Chal- 

 lenger, Zoology, vol. 9, 1884, pi. 56, figs. 10, 11. 



Description. — Test flask-shaped, broadly rounded at the base, 

 abruptly narrowed above into a long tubular neck, whole surface 

 very finely and evenly hispid; aperture rounded. 



Length 0.60 to 0.95 mm. 



Distribution. — This species occurred in the North Pacific material 

 off the Hawaiian Islands, Nero station 2049 in 2,226 fathoms, off 

 Japan, Albatross station D4950 in 529 fathoms, bottom temperature 

 38.9° F., in Gaspar Straits, North Pacific Exploring Expedition, 

 Captain Rodgers, and at several Nero stations along the line of sound- 

 ings between Yokohama and Japan, as follows : 1 137 in 2,250 fathoms; 

 1160 in 1,907 fathoms; 1163 in 2,049 fathoms; 1209 in 660 fathoms; 

 1264 in 2,080 fathoms (type-locality); 1306 in 1,208 fathoms and 

 1310 in 518 fathoms. 



Type.— Cut. No. 8526, U.S.N.M. 



This species, which has been included in Lagena Isevis, has a very 

 characteristic form and is as far as I have observed invariably hispid. 

 In fact in selected material this form has been taken out first with 

 a low-power lens on account of form alone, and has always been found 

 hispid when examined with a higher-power lens. It seems worthy 

 of being separated from the smooth, more pyriform L. Isevis.

1, fig. 5. — Sidebottom, Journ. Quekett Micr. Soc, vol. 11, 1912, p. 384. 



Description. — Test subglobular, broadest slightly below the mid- 

 dle, apertural end broadly truncate with a raised rim about the 

 aperture at some distance; apical end with an external tube usually 

 somewhat curved; wall of the test rough granular. 



Length 0.4 to 0.6 mm. 



Distribution. — The only occurrence of this species in the North 

 Pacific material examined is Nero station 2037 in 55 fathoms off the 

 Hawaiian Islands.
