'Specimens referred to J. longifoUus (Stb.) Brongn. 



^The specimens figured from Missouri under this name were used as types of C. oi-atus Lx. and 

 C. diclioiomus Lx. 



•Tlio specimens from Clinton tlius recorded represent tlie Linopterls yUkeraonensia. 



■•Type of the genus Omphalophloioa.

" Mariopieris sphcnopteroidea (Lx.) Zeill. 



'''Aloiojjteris JVinslovii n. sp., from the Missouri specimens. 



'■^A species concerning which there is much uncertainty in the American material. All the

 devlnia of Brongniart. 



'* Badicites capillacea (L. and H. ) Pot. 



'"Specimens from Missouri identified with this species are referable to Mariopteria xphenopieroides 

 (Lx.) Zeill.
