formed; the area slightl}^ back from the aperture smooth, the aper- 

 ture itself with a slightly everted lip, tooth simple. 



Length 1 to 1,25 mm. 



Distribution.— ly^Q specimen (Cat. No, 13836, U.S.N.M.) from 

 Albatross station D5570, north of Tawi Tawi, 330 fathoms (604 meters). 

 It also occurs off Romblon and off Jolo. 



These stations are all, except the type station, in comparatively 

 shallow water, ranging in depth from 19 to 78 fathoms (35 to 143 

 meters). Bottom temperature in shallow water, 75.7° F. (24.2° C); 

 in deeper water, 52.3° F. (11.2° C).

In its typical form this is an elongate test, with the chambers having 

 the outer peripheral face broadly rounded, but flattened and orna- 

 mented with a number of fine longitudinal costae, closely set, the 

 sides meeting the peripheral face nearly at right angles, making a 

 definite angle at either side; the aperture with a simple and slightly 

 bifid tooth. This species hi the Philippine regions reaches a length 

 of 1.5 mm, or more. The specimen I figured from the North Pacific ^* 

 does not belong to this species. In the Philippines very typical 

 specimens occurred at nine stations, ranging in depth from 27 to 

 303 fathoms (50 to 554 meters), the average depth being 133 fathoms 

 (243 meters). Bottom temperatures are given for three stations, 

 ranging from 52.3° F. to 55.8° F. (11.2° to 13.2° C), with the average 

 temperature 53.8° F. (12.1° C). 



This species includes the follownig localities: Off Romblon; 

 between Marinduque and Luzon; Jolo Sea; eastern Palawan; north of 

 Tawi Tawi; and to the south, one station in Darvel Bay, Borneo,
