the form and venation of the pinnule, in the apical part of 
which the main vein is reduced to a mere line, but continues 
to the apex. The lateral veins are straight, mostly simple 
and arched upwards. The similarity is further increased by 
dots between the veins of both. 
Occasional specimens of Neuropteris show dots more or less 
suggestive of those between the veins of Txniopteris. Mr. 
_ David White has very kindly pointed out to me a specimen in 
the Lacoe collection of the National Museum which has nu- 
merous dots between the veins. Alethopteris maxima An- 
drews (Geol. Surv. Ohio, p. 421, pl. 50, figs. 3, 3b), a species 
from near the base of the Coal Measures of Ohio, is described 
as having numerous small dots between the veins. These were 
regarded by Andrews as probably dots of iron oxid. Lesque- 
reaux (Coal Flora, p. 187) refers to them as “remnants or 
the base of scales similar to those often seen upon leaflets of 
species of Acrostichum.’ Dots occur between the veins of 
specimens of Megalopteris harttu and M. dentata from Rush- 
ville, Ohio. A specimen of Alethopteris, probably A. serlit, 
from Lansing, Kan., shows similar dots. In his report on the 
exploring expedition from Santa Fe to the junction of the 
Grand and Green rivers, Newberry figures (pl. 8, fig. 5) the 
apex of a frond with the following explanation: “Txniopteris 
sp. (?) in fruit; summit of frond, Los Broncos, Sonora.” The 
formation is considered Triassic. The specimen is not men- 
tioned in the text. The figure is indistinct, but the dots seem 
to be small, close, and placed much as in the specimens from 
the Kansas Permian. 
The possibility of these bodies being sporangia is discussed 
in the writer’s paper referred to above. No additional in- 
formation having been obtained, the question of their function 
must now, as then, remain an open one. 
Several specimens of this genus bear on or near the rachis 
elongate-elliptical scars, resembling very closely those of Ma- 
croteniopteris magnifolia (Rogers) Schimper as described and 
figured by Professor Fontaine in his ““Monograph on the Older 
Mesozoic Flora of Virginia,” page 18, plate 4, figures 1 and la. 
Two scars are seen in succession on the rachis of a specimen of 
T. newberriana. Professor Fontaine’s description is taken 
from the depression, while in this specimen the scars project.
