Variations. — The oeciostome of our ovicelled specimen was well preserved in 

 form, very large, salient, and auricular. Unfortunately it was broken in cleaning 

 the specimen. It was larger than the oeciostomes figured by Smitt and by Miss 

 Robertson, and it corresponded more to Osburn's figure. 



This is a polar species, as it does not pass beyond the fortieth parallel in the 

 Atlantic and the thirtieth parallel in the Pacific. This is the first time that it has 

 been found fossil.
