ai'c proljtibly the types. They are easts in a yellow argillaceous liiuestone; 

 IK) hjcality is o-iven. I was permitted to make rubber squeezes from the 

 casts, and PL III, fig. 10, represents one of tliem. No further remarks 

 seem necessary. In tlie United States National Museiini is a cast of u 

 Flabellum from Eutaw Springs, South Carolina. In size, shape, etc., this 

 cast agrees in toto with Conrad's FlaheUmu ivailesi. This is intei'esting, as 

 the specimen comes from one of Ijonsdale's original localities, l^ecause of 

 the fragmentary character of the material F. cnneifonne was originally based 

 upon, we can not fix the exact variety of the species that was Lonsdale's 

 type, but we can be sure that it was eitlier what Conrad called F. wailesi 

 or a form between var. wailesi au(\ \:\v. pavlijiplnilhini.

This variety may be recognized l)y its compressed cuneate form, rather 

 thick wall and septa, its smooth external surface, and its poli.shed and thick 

 epitheca. It passes directly into the form figured in PI. Ill, fig. 18, wliicli 

 lacks tlie latei'al wings entirely, whose sides diverge at a wide angle, and 

 approaches the form that I have named var. arut/forme.
