much as in Q. parlceri. It is not as common as the following variety, 

 but has occurred at eight stations in the region, ranging in depth 

 from 14 to 260 fathoms (25 to 476 meters). 



The following localities are represented: Malampaya Sound, 

 Palawan Island; Palawan Passage; Sulu Archipelago, off Tawi Tawi; 

 off Jolo; China Sea, off southern Luzon; and one station to the south 

 in Sibuko Bay, Borneo. 



Quinqueloculina kerimbatica, var. reticulo-striata — Material examined. 



QUINQUELOCULINA KERIMBATICA, ?ar. PHILIPPINENSIS, new variety. 



Plate 89, figs. 2, 3. 



Description. — Test elongate, quinqueloculine ; peripheral margin of 

 the chambers broadly rounded, sides convex, surface ornamented; 

 the peripheral face with regular reticulations with thin walls between, 

 large but very regular, sides either with the reticulate pattern en- 

 tire, or becoming obsolescent or even wanting, especially in older 

 specimens; apertural end of the chamber projecting and contracted 

 to form an exsert cylindrical neck without ornamentation, with a 

 thin border, not thickened, but with a phialine lip and a simple 

 bifid tooth. 



Length seldom exceeding 1 mm. 



Description. — Type specimen (Cat. No. 13510, U.S.N.M.) from 

 Albatross station D5159, Sulu Archipelago, Tawi Tawi Group, in 

 10 fathoms (18 meters). 



It has occurred at numerous stations, all but one in the Philippine 

 Archipelago. There are 32 stations, ranging in depth from 10 to 

 500 fathoms (18 to 914 meters), the average depth being 62 fathoms 

 (1 14 meters) . Bottom temperatures are given for only two stations — 

 one in 375 fathoms, 56.4° F. (13.5° C), the other in 50 fathoms 

 (914 meters), 76.3° F. (24.6° C). Therefore the average, including 

 the various shallow-water stations, would be close to the latter 

 figure. The species is abundant in shallow water and becomes less 

 common as depths increase above 50 fathoms (91 meters). 



These stations include the following localities: Tacloban Anchor- 

 age; China Sea, off southern Luzon; Sulu Sea, off western Mindanao,
