A new species, 7 eniopteris Missouriensis, from the Lower Coal 
Measures of the Carboniferous in Henry Co., Mo., is described 
and figured, with notes on its probable generic and specific allies, 
and a diagramatic presentation of the supposed genology and 
relations of the group, beginning with the Lower Devonian 
Megalopteris and terminating, in its greatest extension, with 
Danea in the Jurassic. It appears to be intermediate in its char- 
acters between Zeniopteris and Alethopteris. A. H. 
Thuidium intermedium, Philibert (Revue Bryologique, xx. 33, 
1893). 
Six pages are devoted to the group of 7huidium tamariscinum 
including 1. delicatulum, T. recognitum, and a new species, 7. 
intermedium, characterized by revolute leaf margins like 7? del- 
catulum, with the veins of the stem-leaves disappearing in the 
middle of the leaf, the terminal cell papillose, as in our two 
American species, the perichztium not ciliate as in 7) recognitum, 
and the annulus persistent, of indistinct, small, square cells as in 
Z: camariscinum. An excellent key accompanies the description.
