character of their markings, from the most delicately striate to 

 the most coarsely costate types, the latter predominating among 

 the fossil forms. 



21. Miliolina scrobiculata Brady. 



Miliolina scrobiculata Brady, 1884, Foram. 'Challenger,' p. 173, pi. cxiii. 

 fig. 15 a, b, c. 



Fossil only. Quite a number of small specimens have been 

 observed which agree very clearly with Brady's description and 

 figure. Brady's specimens were from shore-sand at Madagascar 

 and Nares Harbour (Admiralty Islands) in seventeen fathoms, and 

 there appears to be no other record either recent or fossil, but 

 Brady admits that his form is probably only a local variety of 

 M. bicornis, and as such it might be expected to occur wherever 

 M. bicornis is abundant.

Fossil only. The specimens exhibit a marked discrepancy in 

 size, the majority being very small. This probably indicates a 

 different source of origin. The species has been recently recorded 

 as a Tertiary fossil by F. Chapman, and according to Brady the 

 geological range of the species extends back to the Miocene beds of 

 the Vienna basin.
