Characters. — At page 14 of Part I M. hicornis was referred to as being allied to 

 M. Brougniartii; the two forms are now recognised as two stages of the same 

 Foraminifer, indeed M. Schlumberger has shown that in their first stage the 

 shell is an Adelosina, and passes on to the three- and five-chambered condition, 

 and that the slight striation visible in the Adelosine stage is retained in M. hicornis, 

 and is much augmented in the more complex M. Brongniartii. M. Schlumberger 

 groups them under Adelosina, as already explained ; here it is thought best to use 

 Miliolina as the generic name.
