FOKAMINTFERA OF NOKTH PACIFIC OCEAN. - 19 



nevertheless the general character is the same, the transverse and 

 longitudinal costae being practically of equal prominence and nearly 

 at right angles with one another.

Description. — Test flask-shaped, nearly circular in cross section, 

 body of test subglobular, neck variable in length, usually rather 

 abruptly contracted from the body of the test at its base, surface 

 ornamented with numerous rather fine costse running the entire 

 length of the test, apical end typically broadly rounded, occasionally 

 slightly tapering to a point. 



Length 0.25 to 0.75 mm. 



Distribution. — Bagg records this species from three Albatross sta- 

 tions: H4566 in 572 fathoms, H4567 in 1,307 fathoms, and H4694 

 in 865 fathoms off the Hawaiian Islands. I have had material from 

 Nero station, 2049 in 2,226 fathoms off the Hawaiian Islands, 1309 in 

 891 fathoms between Guam and Yokohama, and at three Albatross 

 stations— D4900 in 139 fathoms, D4958 in 405 fathoms, and D5056 

 in 258 fathoms, all off Japan. 



There are many forms of striate Lagenge, and it is very uncertain 

 from the material I have had at my disposal where to draw lines of 

 demarcation between forms. Unless there have been definite charac- 

 ters which have had some appearance of stability, I have preferred 

 to place them under L. striata. Certain other forms have occurred 

 in some numbers and have had rather definite characters, and for 

 these certain names have been used to distinguish them here.

Description. — Variety differing from typical L. striata in the neck, 

 which is subcorneal with several prominent platelike costae and the 

 apical end with numerous short spines, usually curved outwardly. 



Length 0.65 mm.
