DESCRIPTION OF SPECIES. 
CRY PTOGAMTA. 
THALLOPHYTA. 
Order CHONDRITE. 
CHONDRITES FLEXUOSUS Newb. n. sp. 
PL. I, figs. 1, 4. 
In various localities the Amboy Clays are found penetrated in every 
direction by vegetable fibers which are imperfectly shown in the figures 
now given. These specimens are evidently the remains of fresh-water 
fucoids or sponges. They are apparently not the rootlets of aquatic plants, 
because they are not found connected with any stems, and they should 
apparently be classed with similar organisms which have in different forma- 
tions been generally included in the genus Chondrites and have been 
supposed to be Thallophytes. No detailed description of these specimens 
is necessary, but they will be recognized wherever found by the figures now 
published. 
In Debey and Ettingshausen’s Die Urweltlichen Thallophyten von 
Aachen,’ PI. II, figs. 6 and 8, similar organisms are represented, to which 
our specimens are closely allied. They differ, however, in the long and 
flexuous tendrils, which are less distinctly connected with a parent stalk.
