Seventy-one species, represented by 614 



specimens. 



* It is worth remarking that Stigmaria is generally absent in the shales and concre- 

 tions of coal No. 3. This may account for the absence of species of large Sigillaria. 

 The deep part of the swamps appear to have been filled mostly with stems, floating 

 •branches or roots, and leaves of Asterophyllites foliosus. 



f A remarkable specimen, sent also for determination by Mr. Wilbur. The end of 

 the fruit is truly flattened by a deep impression of a leaf of Callipteris Sullivantii, 

 proving that even the hardest veinlets have been softened to a mere paste by the pro- 

 cess of emerecausis, or slow combustion in water.
