 Brady). 



Distribution. — Brady recorded this species from three Pacific sta- 

 tions, one of which is in the North Pacific, Challenger station 232, in 

 345 fathoms on the Ilyalonema-ground south of Japan. Millett 

 records the species from the 

 Malay Archipelago. I have 

 not found the species in the 

 material I have examined. 

 The ' above description and 

 figures are from Brady. 



As noted by Millett this spe- 

 cies has certain characters 

 more like some of the Rotalidse 

 than like any of the other species of Textularia. In its aperture, also as 

 figured both by Brady and by Millett, this same resemblance is noticed. 

 It may be a Discorbina, with chambers extending half way about the 

 circumference of the test, but a study of the apical characters and 

 the arrangement of the early chambers should determine this.
