Although this is a very distinct form, and easily recognised, it 

 seems to have escaped the notice of authors generally, and has 

 been figured only by Brady and Egger. 



In the Malay Archipelago it is rare, but it has been noted at 

 two Stations in each Area. 



Brady says that it is a coral-reef species, and all the Stations 

 at which it occurs, recorded by him, are in the Pacific and Indian 

 Oceans. The solitary ' Gazelle' Station is Mauritius.

The structure of the balloon- chamber, characteristic of this 

 species, with its internal float, has been recently so thoroughly 

 worked out by Earland, that it will suffice here to call attention 

 to his paper on the subject in the Journal of the Quekett Club 

 referred to above. 



The species is well represented in the Malay Archipelago and 



occurs at many Stations, but is most abundant in Area 1. The 



examples vary considerably in form, some being as flat as a watch- 



, case whilst others equal in height any of those figured by Mobius 



or Goes. 



Still more numerous is an interesting variety in which the 

 balloon-chamber is always much wrinkled, and is apparently devoid 

 of pores or internal tube. This variety is never depressed, and 

 seldom varies from the contour shown in the figure. Like the 

 normal form it is most abundant at the Stations in Area 1.
