This variable species is only represented by a long, islender, 

 compressed form. The chambers are upright, slightly inflated, and 

 textulariau throughout the entire length of the test. The basal 

 chamber is armed with a long stout spine. The orifice is com- 

 pressed. Six occur.

The examples agree with Millett's figure in the above reference. 



Bifarina Parker and Jones. 

 Bifarina macMnnonii Millett, var. rohusta, nov. var. (PL III, figs. 17, 18.) 



This variety is much more heavily built than the type-form. 

 The tubercles are large and the virguline cluster of chambers also 

 are tuberculate. The test is opaque, and all the interstices of the 

 later chauibers are rough. I have a somewhat similar test from 

 the "Challenger" Station Xo. 185. Two occur.

Some of the tests agree fahdy well with Eeuss's figure, and 

 others with the "Challenger" fig. 23. The longer specimens
