90 TRIASSIC FISHES AND PLANTS. 
CuerroLeris Miysterr Schimper. 
Pl. XXII, Figs. 4, 4a. 
In my general sketch of the Triassic. flora I have referred to this plant, 
and have said perhaps all that it is necessary to say in regard to it. I 
will only add that the foliage which I have described as expanded in the 
same plane, and having somewhat the general aspect of that of Thwa or 
Libocedrus, closely resembles that figured by Schenk in his Fossile Flora 
der Grenzschichten, and the cone scales are also nearly identical with those 
he represents; so that there would seem to be no good reason why they 
should be regarded as distinct. Schenk calls this plant Brachyphyllum Min- 
steri, but Schimper has shown that the digitate cone scales separate this 
from all other species of that genus, and he makes it the type of his Cheiro- 
lepis. The pinnate arrangement of the branchlets of our plant, which must 
have given it the general aspect of Thuja, though the leaves are quite dif- 
ferent, is not shown in Schenk’s figures, and it is therefore possible that 
this will constitute a specific distinction ; but with so many other characters 
in common it is scarcely probable that this is not also shared by the Euro- 
pean and American plants. 
OTOZAMITES LATIOR Saporta.

On another page of this memoir I have referred to the geological im- 
portance of this plant, which is one of the several species common to our 
Upper Triassic rocks and the Rheetie of Europe. Up to the present time 
we have found this only at Durham, Conn., but it is there quite abundant. 
The general character of the fronds is fairly represented in the figures now 
given. They are from one foot to perhaps two feet in length, and from two 
to three inches wide; broadest in the middle, where the obliquely set pin- 
nules are two inches in length, narrow, linear, and pointed. Toward the 
summit of the frond they are shorter and more crowded, while near the 
base they are still shorter and somewhat irregularly placed. On the upper 
side of the rachis the bases of the pinnules are elegantly adjusted to one 
another in alternate order, the line of contact between them being sinuous or
