Fig. 1. Side view of " Acervnline" specimen from Raine Island, 

 part of the outer "balloon" chamber removed, to 

 show the inner " float " chamber with its basal 

 entosolenian tube. The lobulated pleats of the " float" 

 chamber, and its attachment to . the Acervuline 

 chambers, are also shown. The outer " balloon " is 

 also attached to the lower Acervuline chambers, but 

 does not touch the " float " at any poiat. 



Fig. 2. The same specimen viewed from the underside or base. 

 The " balloon " is seen partly enveloping the " float." 

 Where a part of the " balloon " has been removed, the 

 Acervuline chambers can be seen projecting beneath 

 the "float." 



Fig. 3. A large bottom specimen of the " Discorbine " type from 

 Raine Island, viewed from the top. The balloon 

 chamber is entirely hidden by the spreading Dis- 

 corbine chambers.
