The following is the original description: 



Te.st free, quinqueloculiue. The walls of the chambers thick, irregularly furrowed 

 in all directions with broad, deeply gouged-out channels, running obliquely and irreg- 

 ularly across the face of each chamber and generally connecting with a deeper straight 

 furrow excavated down the peripheral edge. This straight peripheral furrow, when 

 exposed on an earlier chamber in the center of the test by the quinqueloculine 

 arrangement of the shell, affords a A'ery striking appearance by contrast with the 

 transverse furrows on the surface of the surrounding chambers. Aperture large and 

 furnished with a prominent tooth. The oral end is usually but slightly produced, 

 but in some individuals the aperture is situated on a produced neck. The ridges 

 between the furrows are flat on the top — i. e., the furrows are cleanly gouged out of 

 the shell substance. 



The typical form of this species with irregular, excavate peripheral 

 faces, and with fiat-topped ridges, is very rare in the Philippine 

 material, heing replaced hy varieties showing very constant char- 

 acters, 



Tlie typical form occurred at the following stations: Tara Island, 

 in shallow water, and D5143, in 19 fathoms (35 meters), ofT Jolo. 



The types, of which the above is the original description, were 

 from the Kerimha Archipelago, off southeastern Africa, described 

 by Heron-Allen and Earland." 



Quinqueloculina keriinbatica — Material ea:aniined. 



QUmQUELOCUHNA KERIMBATICA, var. RETICULO-STRIATA, new variety. 



Plate 89, figs. la-c. 



Description. — Test with peripheral faces rather squarely truncate 

 I nd ornamented by longitudinal narrow costae, the sides of the 

 chambers with oblique areolae; the apertural end contracted and 

 terminating in a short cylindrical neck, and thin philaline lip with a 

 bifid tooth. 



Length 2 mm. 



Description. — Type specimen (Cat. No. 13488, U.S.N.M.) from 

 Albatross station D5276, in 18 fathoms (33 meters), China Sea, off 

 southern Luzon. 



This variety is larger than variety phili'p'pinensis , and is closer to 

 the typical form of the species; but the peripheral face of the chamber 

 has sharp, usually very even costae, and the sides are reticulated
