'?TlTANOPHTLLUM BeITTSII n. Sp. 



The specimen in hand, from what seemg to be the thick base of the 

 leaf, though flattened, seems to represent a system of bands similar to that 

 illustrated by Renault.^ They are somewhat finer than those in the French 

 type. The surface is distinctly and zonally striated. The incurving of the 

 bands and nerves accompanying the contraction of the base of the leaf is 

 very clearly seen. As flattened, the fragment seems to have a thickness of 

 about 2 mm. While our flattened specimens are, possibly as the result 

 of pressure, thinner at the base than are the French specimens, they appear 

 to be somewhat larger. 



The generic identity of the American material with the French seems 

 probable from the description communicated by Dr. Britts, though it can 

 not be absolutely assured until more and better material shall have been 

 examined. The slightly narrower bands in leaves apparently less thick and 

 much larger, the leaves measm-ing 6 to 12 inches in width and 4 to 6 feet in 

 length, distinguish our plant, supposing it to belong to Titcmophyllum, from 

 the Titcmopliylhim Grand 'Euryi, though in view of the resemblance of the 

 impression to certain compressed stems or large branches, the formal diag- 

 nosis of our species should not be given until more satisfactory material, 

 susceptible of good illustration, is at hand. The specimens from Missomi 

 are entirely carbonized and strongly compressed. 



Localities. -^l^orth and Wood coal shaft, one-half mile east of North's 

 Station on the Kansas City, Clinton and Springfield Railroad, the vein 

 worked being an extension of Jordan's coal, U. S. Nat. Mus., 6168. A 

 smaller fragment, possibly of the same nature, comes from Gilkerson's 

 Ford, U. S. Nat. Mus., 6169.
