Lagena vulgaris, var. spinicosto-marginata Rymer-Jones, Trans. Linn. Soc 

 London, vol. 30, 1872, p. 57, pi. 19, figs. 34-36. 



Description. — Test ovate, compressed, wall smooth, periphery 

 keeled usually, with several spines symmetrically arranged about 

 the border; aperture fissurine. 



Length about 0.5 mm. 



Distribution. — Apparently this species has not previously been 

 recorded from the North Pacific. It has occurred at three Nero 

 stations; 91 hi 1,983 fathoms and 170 in 1,990 fathoms between the 

 Hawaiian and Midway Islands and 862 in 1,550 fathoms off Luzon, 

 Philippine Islands. 



Both three- and five-spined specimens occur, but the range of 

 variation shown by Sidebottom does not seem to exist in our speci- 

 mens. The figured specimen is very similar to the one figured by 

 Sidebottom as Lagena fasciata Egger, var. spinosa Sidebottom, 1 

 but our specimen lacks the ornamentation of L. fasciata. Otherwise 

 the two are very similar. 



LAGENA TRUNCATA H. B. Brady. 



Plate 19, fig. 3. 



Lagena truncata H. B. Brady, Rep. Voy. Challenger, Zoology, vol. 9, 1884, p. 

 457, pi. 56, figs. 31, 32. 



Description. — Test elongate, pyriform; greatest breadth below the 

 middle, aboral end broadly rounded; apertural end obtusely rounded; 

 wall smooth; aboral end with two or more short spines; aperture 

 radiate. 



Length 0.4 to 1.0 mm. 



Distribution. — This species occurred in material from Nero station 

 1065 in 1,321 fathoms between Guam and Yokohama. 



Brady speaks of the aperture as " either round or fissurine" but 

 the specimen figured has a decidedly radiate aperture. The optical 

 section gives the form and comparative length of the entosolenian 

 tube.
