FORAMINIFEKA OF THE PHILIPPINE AND ADJACENT SEAS. 465 



Other localities represent 7 stations, ranging in depth from 18 to 80 



fathoms (33 to 146 meters), the average depth being 34 fathoms (62 



meters). Bottom temperatures are given at 2 stations, ranging from 



58.6° F. to 75.7° F. (14.7° C. to 24.2° C). These locahties are China 



Sea, off southern Luzon; off Romblon; off eastern Pan ay; and between 



Bnrias and Luzon, 



This species is a peculiar, and, in the Philippine material, a very 



distinctive one. The peculiar twisted character, long slender form, 



with the extended smooth neck, and especially very coarse material 



of the test, all make it conspicuous among the other arenaceous 



species that occur with it. It is found in comparatively shallow 



water. 



Triloculina tortuosa — Material examined. 



Genus FLINTINA, new genus. 



Description. — ^Test free, m its earliest stages quinqueloculine, fol- 

 lowed very early by a triloculine development, wliich is maintained 

 in all the later chambers, which become planospiral, usually takmg 

 three to make a complete cycle; wall imperforated, porcellaneous; 

 aperture with a large orifice, with a thickened border, and large 

 complex tooth. 



Type of the genus. — Flintina hradyana, new species. 



This genus, while somewhat like Planospirina, differs from that 

 genus in its development. Planospirina has no quinqueloculine or 

 triloculine stages, but has a planospiral test from the beginning. 

 Flintina, on the other hand, has a derivative from Triloculina through 

 the quinqueloculine stages. 



It is named in honor of the late Dr. James M. Flint, whose excellent 

 work on the Albatross Foraminifera is well known. 



FLINTINA BAKTSCHI. new species. 



Description. — Test generally triangular; last-formed whorl of tliree 

 chambers, polygonal in transverse section, the apertural face flat or 

 slightly concave, the lateral faces generally somewhat concave with a 

 sharp angle between the apertural and lateral faces; in the last- 

 formed chamber the lateral face is somewhat convex, the chamber
