1 6 MALONE JURASSIC FORMATION OF TEXAS. [bull. 266 
in the western segment of the Malone Hills would represent the Thetfi \ 
and the Iota in that quarter. 
(3) That the conglomerates above the gypsum in the east face oi 
Malone Mountain, at the southern end of the mountain and at the 
transverse anticline a mile farther north, would represent, in part at 
least, the Iota. 
(4) That the Theta in the eastern slope of the mountain at ite 
southern end would, if present, belong about at the summit of the 
gypsum, and that it either has been removed by erosion during the 
formation of the conglomerates or is possibly represented there by 
the upper part of the gypsum itself. 
The fossils obtained by me from the eastern slope of the mountain 
were found in a ravine at the base of the mountain, in a horizon of 
impure limestone, at the passage from conglomerates like those of the 
Iota to limestones like those of the Kappa, forming part of an 
obliquely transverse anticline about a mile north of the southern end 
of the mountain : those collected at the latter locality by Doctor Stan- 
ton were obtained in part from limestones somewhat higher in ther 
anticline. 
DISTRIBUTION OF FOSSILS IN MALONE DISTRICT. 
A large number of the fossils herein described will be found 
recorded as having been collected by Doctor Stanton at a number of 
points on or near Malone Mountain, especially on the western slope 
and foothills. The great majority of these had previously been found 
at the notable locality east of Malone, but several willbe found listed 
from the mountain or its western foothills only. Among these are 
the Nautilus, a feAv other Mollusca, and the two echinoderms. 
How prolific the Malone formation is in fossils at the several col- 
lecting stations, and how much the original Malone Hills locality 
excels the others, may be seen by the following lists:
