and Pachyphyllum, standing nearer the former. As this single specimen does not 
. guffice to establish a new genus, it is perhaps best provisionally to regard the plant 
as a Cheirolepis. In that case it might be called Cheirolepis diffusa. 
In this connection it is proper to-state that although Emmons says that he made a 
rich collection of the North Carolina Older Mesozoic fossil plants, I know of the exist- 
ence of no collection of these plants available for study. ' 
Accompanying these plants of Dr. Lea there are several fine specimens of ganoid 
fishes obtained by Emmons from the shales associated with the coal of North Caro- 
lina. They are worthy of careful study. 
Respectfully, Wm. M. Fonraine. 
Dr. F. H. Knowlton received from Prof. I. C. Russell some pieces of 
fossil wood from the Trias of North Carolina, from which he made six 
slides. These have not thus far been figured, but after an examina- 
tion of the slides Dr. Knowlton was able to make to Professor Russell 
the following statement, which the latter published in his Correlation 
Paper on the Newark System. At my request Dr. Knowlton has 
kindly drawn the figures and furnished the following descriptive 
notes: 
DESCRIPTION OF A SMALL COLLECTION OF FOSSIL WOOD FROM THE 
TRIASSIC AREA OF NORTH CAROLINA. 
By F. H. Kyow ron. 
In 1885 Prof. I. C. Russell, then of the United States Geological 
Survey, submitted to me a small collection of fossil wood made by 
himself in the Triassic area of North Carolina. He requested a brief 
report on this material, which I made, and which he published in his 
Newark System! in 1892. Recently Professor Ward, who is engaged 
on a systematic review of the fossil plants of the Triassic of this coun- 
try, has asked for a more detailed description of this wood for use in 
his report. The following notes are the result of this study. 
This collection consists of about a dozen specimens, representing 
the following localities: Triassic strata between Walnut Cove and 
Germantown; 1 mile west of Polkton; and Lockville, all in North 
Carolina. None of the material is well preserved, the structure having 
suffered greatly -in the process of fossilization. Six of the best-pre- 
served pieces were selected and thin sections cut from them. Of these, 
three proved to have been so poorly preserved as to be worthless for 
purposes of study, and the results obtained are therefore based on the 
three remaining pieces. 
I stated in my brief report to Professor Russell’ that, with the possi- 
ble exception of one piece, I was able to identify them with Avaucarioxy- 
lon arizonicum Knowlton,” a species described from the Shinarump 
group of Arizona and New Mexico, and since detected, or at most
