The examination of any considerable number of examples of this 
species will show that there is always going on a struggle to deviate 
from the nautiloid form and to become evolute, at the same time 
becoming more compressed and more or less acute at the margin, 
finally merging into such forms as H. compressum and E. fontinense. 
The Malay specimens have the usual range of variation ; they are 
very numerous, and are restricted almost entirely to Area 1 .

In all the specimens the shell structure is coarse and the aperture 
simple. Its range in the Malay Archipelago is very restricted, although 
where it occurs the individuals are numerous. 
According to Brady it is one of the commonest deep-water species 
of arenaceous foraminifera. Goes records it from the Pacific and from 
the Caribbean Sea.

The specimens are all characteristic, with little or no tendency to 
variation. It is most abundant in Area 1.
