This Species is similar to Virgulina schreibersiana 

 Czjzek; but it has more segments and is, as a rule, more apiculate, 

 while its later, rapidly enlarged, irregular segments become nearly 

 biserial. 



There are eight chambers in the form selected from slide 2 to 

 illustrate this species and the margin is more or less limbate. We 

 believe that this species is more representative and abundant than 

 either of the two included with it.

 A six-chambered transverse section of slide 2 appears to belong 

 here. This is to be regarded as a .subvariety only of V. 

 squamosa in which the ends are rounded; inV. squamosa 

 the distal margin is sharp and almost apiculate. 



Virgulina sp. 



Plate 2, figure 13 



On slide 3 occurs a symmetrically, rapidly expanding Virgulina 

 which we are unable to place, as all published types of this genus 

 seem to be relatively narrow in proportion to length. This shell 

 is acuminate but the widely expanded anterior end is like 

 Textularia trochus. The ultimate chamber is arched 

 but somewhat angular and we believe the form has never been 

 described. As it is impossible to determine its entire construction, 

 we do not wish to give it a specific name. The shell measures in 

 length 0.25 mm and 0.13 mm across its oral extremity. 



Genus BOLIVINA d'Orbigny 



The genus Bolivina has already been discussed under Virgulina 

 and compared with its relatives Bulimina and Textularia. It is a 

 smaller type than Textularia, from which it differs always by its
