This species, which seems to be rare in the Indo-Paeific region 

 about coral reefs, is recorded by Chapman from Funafuti, and occurs 

 in the Philippine region from Albatross station D5154, Sulu Archipel- 

 ago, off Tawi Tawi, in 12 fathoms (22 meters), and is very common 

 at D5357, north of Balabac Strait, 68 fathoms (125 meters). This 

 is a very peculiar species, at first not resembling the foraminifeia, but 

 apparently belonging to this genus. Some of the largest specimens 

 measure nearly 20 mm. in height. Figures given by Chapman 

 show well the characters of its form and arrangement of chambers. 

 The big rootlike offset cham-bei-s are characteristic in all the large 

 specimens, apparently liaving a definite use in supporting the rest 

 of the column. This is probably the same as the species described 

 by Dakin" from off Ceylon, as a comparison of his figures will show.

This species, which is characteristic of coral-reef regions, is very 

 common, attached to shell fragments and other objects in shallow 

 water, except in the southern part of the Archipelago. Although 

 probably widely distributed in the region it has been recorded and 

 material saved from the following stations: D5146, Sulu Archipelago, 

 off Siasi, 24 fathoms (44 meters); D5179, off Romblon, 37 fathoms 

 (68 metere); D5217, between Burias and Luzon, abundant at 105 

 fathoms (193 meters) ; and D5357, north of Balabac Strait, 68 fathoms
