32 MALONE JURASSIC FORMATION OF TEXAS. [bull. 266. 
beds from No. 4 to No. 19, inclusive, are overturned. It will be seen 
also that the succession of rocks and fossils is similar to that found 
on the east slope of the mountains near Quitman Canyon, and that 
there is no place for the great sandstone series of the " Mountain 
bed " within the Washita division. It must be older than the Orbi- 
tolina limestone. 
Eagle Mountains. — These mountains, which lie 10 miles east of the 
southern end of Quitman Mountain, are composed mostly of igneous 
rocks, but sediments are exposed on their flanks. My examinations 
were along only the western base, where there are some exposures of 
Fredericksburg limestone and shales and apparently some Trinity 
limestones. Mr. Tan" reports Upper Cretaceous and the Orbitolina 
limestone on the other side of the mountains, and fossils in the col- 
lection of Prof. W. F. Cummins, at Dallas, indicate the presence of 
upper Washita beds a 1 mile north of gap in Eagle Mountains." 
Sierra Blanca. — This group of conical peaks, about 6 miles north 
west of the railroad station of the same name, is also composed o 
igneous rocks with Cretaceous sediments around the base. On th 
southwest side of the main peak there are fossiliferous exposures o 
Fredericksburg age noteworthy for containing Exogyra texana an 
Nodosaria texana in the same bed. The same association is found i 
the Finlay Mountains also. Beds of about the same age with K. tex 
ana and Actceonella <h>r<um occur in Flat Mesa, about 4 miles east. 
In the saddle between the main peak and the north peak of Sierr 
Blanca there are considerable exposures of very fossiliferous Washit 
beds with many characteristic species. 
Finlay Mountains. — These hills begin about 4 miles north of th 
north end of Malone Mountain and 6 miles northwest of the main pea 
of Sierra Blanca and extend several miles to the north and northwest 
They were rather hastily examined in the hope of finding an exten 
sion of the Malone beds, but the only fossiliferous beds seen belong t 
the Fredericksburg division of the Cretaceous, including the horizo 
of Actceonella dolium. There are many intrusive masses of igneou 
rocks and at one locality a considerable development of a coarse cal 
careous conglomerate whose relations were not definitely determined 
though it seemed to belong to the Cretaceous. 
Other localities. — Other exposures in the neighborhood of Sierr 
Blanca station were examined, especially Bluff Mesa and Devils Ridgl 
without very definite paleontological results. The top of Bluff Mes 
P. miles southwest of Sierra Blanca, is composed of Orbitolina lim 
stone, and it is probable that the underlying beds belong within th' 
Trinity division. 
The Orbitolina limestone, the Quitman bed, and a considerabl 
thickness of Fredericksburg beds are well exposed in the neigh bo
