12 M ALONE JURASSIC FORMATION OF TEXAS. [bull. 26| 
Paso County, Tex., and found that certain fossils were common to 
the locality a mile and a half east of Malone station and to the 
southeastern quarter of Malone Mountain, and in September of that 
year and in the summer of the year following, for the mountain in 
general and its western foothills, by Dr. T. W. Stanton, who founculj 
for these and the eastern foothills an essentially common fauna. 
I arrived at Sierra Blanca station August 19, 1897, and remaineJj 
till September 7, reconnoitering in several directions from that sta-jj 
tion as headquarters and giving the greater part of my time to t'nejj 
Malone district. I examined parts of the eastern slope of Malone 
Mountain, from which also I obtained a few fossils, and observe™ 
from the southern part of the mountain crest, the general relation! 
of the western foothills. But it was to the eastern hills, as inclnd-j 
ing the locality that had yielded the interesting fossils to Mr] 
Wyschetzki and the Messrs. Goodell, that T gave chief attention j 
and from these hills T made a large collection of fossils. The western 
slope and foothills of the mountain 1 was unable to explore for lack 
of time. 
On September 2 Doctor Stanton reached Sierra Blanca and joined 
me in exploring and collecting for a few days, both in Cretaceous! 
localities and in the eastern part of (he Malone district.' Doctor 
Stanton remained in the field after my departure and carried recoiB 
naissance further westward than I had, examining the western slope 
and foothills of Malone Mountain and making a section of the] 
mountain. In the summer of L898, with more time and better 
facilities at his disposal than had been available to either of us id 
1897, Doctor Stanton returned to this part of Texas ami made addi- 
tional collections and a comprehensive examination of the Malonl 
and contiguous territory. Later, with the consent of the Director 
of the United States Geological Survey, Doctor Stanton \^vy gem 
erously turned over to me for study and description all of the marine 
fossils collected by him from the Malone formation in his two expe- 
ditions. Doctor Stanton's geological observations will be given by 
himself in another connection herewith. 
The types collected in the Malone district by the Geological Survey] 
of Texas in 1890 and described in the fourth annual report of than 
survey have in part been loaned to the United States Geological SuJ 
vey by Doctor Dumble and used in preparing this paper. Most oil' 
the species thus early collected are represented by ampler material! 
from later collections. The more important of the specimens of thej jl 
Goodell Malone collection, which were given to me by Mr. Robert \vj| 
Goodell in 1897, and my Malone collection, made in the latter yearj 
have recently become the property of the United States National 
Museum and, first studied in the summer of 1898, have been restudied | 
in connection with the other material. The material on which these
