 Rep. Voy. Challenger, Zoology, vol. 9, 1884, p. 474, pi. 59, fig. 12.

LAGENA AURICULATA H. B. Brady, var. SUBCARINATA, new variety. 



Plate 17. fig. 4. 



Lagena auriculata H. B. Brady, var., Sidebottom, Journ. Quekett Micr. Club, 

 vol. 11, 1912, p. 421, pi. 20, figs. 15-18. 



Description. — Test ovate, somewhat compressed, central portion 

 somewhat irregularly roughened, basal portion or whole test with a 

 wide peripheral keel with two tubular projections from the lower 

 border; entosolenian tube long and sinuous. 



Length about 0.25 mm. 



Distribution. — This variety occurred at Nero station 1300 between 

 Guam and Yokohama, type-specimen, Cat. No. 8535, U.S.N.M., 

 and at Albatross station D4957 in 437 fathoms off Japan. 



This is the variety noted without name by Sidebottom. It seems 

 worthy of some distinctive name that its distribution may be noted.
