arating line. The venation of the smaller fronds seems thinner, 
but becomes proportionally stronger with the size of the frond. 
The apex, however, is decidedly more acute. The species and 
variety occur at the same locality.

Numerous specimens in the collection are so close to Txniop- 
teris newberriana that their reference to that species, at least 
for the present, seems advisable. There are numerous indi- 
viduals, but all more or less fragmentary. Owing to the thin 
texture of the frond the line of cleavage in the matrix is not 
sufficiently marked to expose it completely as in the last species. 
In this character of a very thin frond our specimens differ very 
markedly from the types of the species, which are described by 
the authors as rather thick and coriaceous. The fact that the 
matrix is different in the two cases, the Kansas specimens be- 
ing preserved in limestone while the West Virginia ones were 
in shale, may account in part for this, and possibly for other 
seeming differences. The nerves are figured by the authors as 
leaving the rachis at right angles, but in the description they 
say that the lateral nerves leave “the midrib at a right angle, or 
with a very slight arch immediately at the insertion.” In the 
Kansas specimens the veins near the apex of the frond leave 
the midrib at right angle, those near the middle with a slight 
arch immediately at the insertion, and those near the base with 
a more decided arch at the insertion. In the figures of the types 
the veins are represented as coming out at right angles from 
the rachis throughout the entire length of the frond, the base 
as well as the apex. No specimens have been found in the 
Kansas formation with the peculiar segmentation character- 
izing many of the West Virginia specimens. These two char- 
acters—difference in the origin of the veins, and absence of 
the segmented frond, may prove to be of specific value. The 
present reference is intended as suggestive rather than final. 
In other respects Fontaine and White’s description of the vena- 
tion, “lateral nerves very fine, closely placed and immersed in 
the parenchyma of the frond,” entirely agrees with the Kansas 
specimens, as does also their description of the size and shape 
of the frond, “frond simple, elongate, narrowly elliptical, taper- 
ing slowly to the apex and base.” The largest fronds of our
