Plate 70, fig. 1. 



Description. — Test differing from the typical in the character of 

 the ornamentation, the sutures being thickened on the dorsal side, 

 the periphery with a thickened rim, and basal angle of each chamber 

 with a raised oval development. 



Distribution. — Type specimen (Cat. No. 15355, U.S.N.M.) from Alba- 

 tross station D5301, China Sea off Hongkong, in 208 fathoms (381 

 meters) . 



There are also specimens from nine other stations, ranging in 

 depth from 6 to 208 fathoms (11 to 381 meters), the average being 

 106 fathoms (194 meters). Bottom temperatures are given at six 

 stations, ranging from 50.5° to 76.3° F. (10.2° to 24.6° C), the 

 average temperature being 58.9° F. (14.9° C).

This common species of Globigerina-ooze is abundant, being found 

 at more than 100 of the stations examined. As might be ex- 

 pected the species is most common around the outer coasts of the 

 Archipelago, but is also common in the Sulu Sea and found less 

 abundantly in the more protected waters among the islands. To 

 the southward it occurs at nearly all the stations; Darvel and 

 Sibuko Bays, Borneo; Gulf of Tomini, Celebes; Molucca Passage; 

 between Gillolo and Makyan Islands; between Gillolo and Kayoa; 

 south of Patiento Strait; off Bouro Island; Molucca Sea; Buton 

 Strait; Gulf of Boni; Floros Sea; and Macassar Strait.
