Description. — Test elongate subcylindrical or elongate fusiform, 

 tapering at either end, wall longitudinally striate; translucent. 



Length 1 to 2 mm. 



Distribution. — Brady records this species in the North Pacific from 

 a single Challenger station off Japan in 345 fathoms. Goes records 

 it from the eastern Pacific in 782 to 1,132 fathoms. I have had 

 material from three stations off Japan; Nero stations 1305 in 1,289 

 fathoms and 1309 in 891 fathoms; and Albatross D4843 in 100 fath- 

 oms, bottom temperature 39.9° F. 



Except for its striate surface this species is very close to L. elongata 

 (Ehrenberg).

Description. — Test flask-shaped, body portion subglobular, orna- 

 mented with numerous plate-like costse running the length of the test, 

 a few often more prominent than others, rather closely set and numer- 

 ous, sometimes ending in spinose projections at the apical end; neck 

 variously ornamented by cos tee or annular rings. 



Length 0.35 to 0.65 mm. 



Distribution. — The only North Pacific stations from which I have 

 had this species are all from Guam to Japan; off Guam, Nero station 

 1464 in 891 fathoms; between Guam and Yokohama, Nero stations 

 1065 in 1,321 fathoms and 1313 in 1,716 fathoms; and off Japan, 

 Albatross station D4957 in 437 fathoms.
