the chambers ; orifice situated in a depression on the face 

 of the final chamber. 



This variety seems to be an extreme development of 

 C. bradyi, in which both the planospiral arrangement of 

 the earliest chambers and the obliquity of the biserial 

 chambers is lost. In the C. bradyi, var. stenostegica 

 (Goes) C94), p. 44, pi. 8, fig. 427, the obliquity is very 

 great. I have made the small pores of the test rather too 

 apparent in my drawing. On the back of the test they 

 are hardly discernible. PI. 3, fig. lib, shows an outline 

 of the form viewed by direct light, and PL 3, fig. n2r, the 

 same form viewed by transmitted light. In this latter, 

 the orifices of the chambers show as circular openings for 

 nearly the whole length of the test. Very rare.
