 Nat. Mus., pt. 3, 1913, p. 110. 



Dcscnption. — Test free, branching, consisting of more or less 

 rounded chambers connected by long stoloniferous tubes; wall 

 hyaline. 



This genus includes rather ill-defined forms, suggesting the so- 

 called " wild growth " seen in tlie final chambers of certain species 

 of Poli/morphina. Just what its relations are to the rest of the 

 Lagenidae is not really determined. It seems to occur in the 

 Jurassic and there are one or two recent species. 



RAMULINA PROTEIFORMIS Flint. 



Ramulina protciformis Flint, Rep. U. S. Nat. Mus., 1897 (1899), p. 321, pi. 

 68, fig. 7. 



Description. — Test calcareous, extremely thin and fragile, very 

 finely perforated; surface smooth; in form very irregular and 

 variable, sometimes branching, sometimes with more or less numerous 

 short digital processes, imperfectly segmented, the segments inflated 

 into a great variety of shapes. 



Distrihiition. — I have seen the specimens which Flint had of this 

 species from the Gulf of Mexico, but have no additional stations for 

 the species.
