These locations are from "Permian Brachiopods of West Texas", G.A. Cooper & R. E. Grant, Smithsonian Institution Press, 1972, pp. 127-8. The document can be downloaded from their repository.
Quoting from that document re the location format:
The locations generally are made as map measures from nearby bench marks, instrumentally determined elevations, hill tops, ranch houses, or other convenient reference points. These are often difficult to locate quickly by readers unfamiliar with the quadrangles covering the Glass Mountains. We have, therefore, listed alphabetically and numerically all of these important points to facilitate location of the collecting places.
The United States Geological Survey topographic maps are divided into nine rectangles by intersecting latitude and longitude lines. These are called subquads and are numbered in sequence, beginning in the upper right, in the manner of numbering used in the township range system. Consequently. the subquad in the upper right comer is 1, to the left are 2 and 3. Below 3, in order left to right, are 4 through 6; 7 lies in the lower right comer with 8 and 9 to the left.
Each subquad is further divided into four equal rectangles: northeast, southeast, northwest, and southwest. Each of these rectangles is similarly subdivided. Location is made by reference to the quarter in which the site lies. Thus, a collecting spot may lie in the northwest quarter of the southwest quarter of subquad seven: NW, SW 7.
NOTE: Re the above text. So you essentially read the location backwards. SE, NE 8 means start in subquad 8, go to the NE subquad of it and then the SE subquad of that.
