FORAMINIFERA OF THE PHILIPPINE AND ADJACENT SEAS. 433 



tions range from between 52.2° F. to 54.3° F. (11.2° C. to 12.3° C), 

 the average being 52.7° F. (11.4° C). 



No specimens referred to this species occurred at less than 200 

 fathoms, while most of the specimens of Q. rugosa occurred in much 

 shallower water. The surface in typical Q. contoHa is smooth and 

 matt, and is very different from the pitted surface of Q. rugosa. 

 The stations for Q.contorta are in the following localities: Off north- 

 ern Mindanao; off Jolo; between Jolo and Tawi Tawi: north of Tawi 

 Tawi; and off western Mindanao, all of the stations but the first being 

 in the Sulu Sea, where dredgings were made in comparatively deep 

 water. Heron-Allen and Earland record it as abundant in the 

 Kerimba Archipelago.

QUINQUELOCULINA SCULPTURATA, new species. 



Plate 91. figs. 3, 4. 



Description. — Test elongate, chambers with the outer face broadly 

 convex, sides concave, the angle between the peripheral and lateral 

 faces sharp, chambers much the broadest near the initial end, taper- 

 ing toward the apertural end; peripheral face in the young with 

 deep oblique chambers and ridges, in the later development becoming 

 a coarse reticulation; apertural end very slightly produced, with a 

 single, long tooth. 



Length up to 1 mm. 



Quinqueloculina sculpturata — Material examined. 



Distribution. — Type specimen (Cat. No. 13626, U.S.N.M.) from 

 Albatross station D5143, off Jolo, in 19 fathoms (35 meters). It has 

 also occurred at the two neighboring stations, D5144 and D5145, in 

 19 and 23 fathoms (35 and 42 meters), and D5218, between Burias 

 and Luzon, in 20 fathoms (37 meters).
