 almost no description. He mentions, however, that "some of these 

 specimens are almost unique amongst discoidal Foraminifera in the 

 point of size, presenting a diameter of 2^ inches (63 mm.)." Car- 

 penter's genus was founded on this large species, which comes from 

 "a considerable depth of water off the coast of Borneo." The 

 CJiallenger material gave little to add to the knowledge of this species. 

 However, it has been found occasionally since that time, as the 

 above references show. The Albatross dredged this species in great 

 quantity at D51 79, off Romblon, in 37 fathoms (68 meters) , and some of 

 these specimens were preserved in a large-mouthed fruit jar, in which 

 was a note saying that other specimens in the same dredging were too
