 pi. 11, fig. 20. 



Fornasini, in the above reference, states that there are 

 two examples of Nodosaria proxima, Silvestri, in which 

 thedisposition of chambers, and of the aperture, approaches 

 very much to that of a Marginulina. Some of the Delos 

 specimens agree very closely with Fornasini's figures. 

 About forty examples occur. The second chamber is 

 usually smaller than the initial one, but in some cases 

 they appear to be of equal size. I cannot see my way to 

 separate forms like fig. 29 from the rest ; in my view the 

 whole forty belong to one species, and consist of examples 

 having three, four, and five segments, and in one case six. 

 The longest tests are nearly always curved. The neck is 

 always at one side. Its length varies considerably, as 

 does also the amount of inflation of the final chamber. 

 Rather rare.
