Remarks. — This species is also known from older tertiary 

 strata, but is more commonly met with in the Jurassic and lower

 cretaceous of South Africa. (Author's MS.).

Retnarks. — The distinctive features of this form are the 

 prominence of the sutural lines which mark the junction of 

 chambers, less strongly curved on the septal face than in the 

 nearly allied C. subalata ; and the greater height of the chambers 

 when compared with the .species just mentioned. C. prominula 

 has been recorded from the lower and upper cretaceous of 

 Europe. 



Occurrence. — One specimen (small) ; Jurassic, Greenough 

 River district, West Australia. [2134].
