This subfamily includes many species mainly belonging to Reopliax 

 and Hormosina. The chambers vary in relative length and in their 

 relative position, sometimes closely fitting one over the other, some- 

 times drawn out with long tubular portions between the chambers. 

 There is much difference in the materials used by various species, 

 sand grains being the usual material, but certain species select sponge- 

 spicules and in one species, Reophax membranaceus the test is composed 

 largely of chitinous material.
