 Lagena bicarinata Balkwill andMiLLETT, Journ. Micr., vol. 3, 188^, p. 82, pi. 2, 

 fig. 4. 

 But one station is recorded for this species in the Philippine mate- 

 rial I have examined, Albatross station H4914, in 464 fathoms (848 

 meters), China Sea off southern Luzon, bottom temperature 46.5°F. 



(8°C).

LAGENA LAMELLATA Sidebottom. 



Lagena lam^llata Sidebottom, Journ. Quekett Micr. Club, ser 2, vol. 11, 1912, p. 

 396, pi. 16, figs. 24, 25. 



Descriptivn. — Test pyriform, tapering to a slender neck with spiral 

 markings, wall compound, outer coating thin and flaky, resting 

 upon fine tubular spines which in turn come out from an inner thick- 

 ened wall with a polygonal structure when denuded of spines and 

 seen in surface view or from within. 



Diameter about 0,3 mm. 



Distribution. — The only Philippine material I have seen is from 

 Albatross station D5187, in 225 fathoms (412 meters), Tanon strait 

 east coast of Negros, bottom temperature 53.6° F. (12° C). This 

 is the first record for the North Pacific. The specimens described 

 by Sidebottom were from the South-west Pacific, depths of 505 and 

 484 fathoms (923 and 885 meters). 



This is a complicated test and the specimens showed nothing 

 which will add to the characters as shown by Sidebottom.
