292 W. D. Moore—Footprints in the Carboniferous Rocks. 
Art. XXXIV.—On Footprints in the Carboniferous rocks of 
Western Pennsylvania ; by W. D. Moore. 
In 1846, Dr. Isaac Lea discovered, in the coal strata near 
Pottsville, footprints similar to those discovered by Dr. King 
in 1844. Another example of similar footprints has been dis- 
precisely the same situation geologically were the tracks found 
of which I send you a cast, and rather imperfect drawing. The 
Pittsburgh coal seam is worked on the hill side, above the 
quarry from which these tracks were obtained, by actual mea- 
the left; left three of nearly equal length 
fourth much smaller and shorter, 3 inch; heel 1 inch long; 
d wider. 
The species is dedicated to Dr. Wm. C. Reiter, of Pittsburgh, 
an accomplished naturalist and an intimate friend and fellow 
e 
of reptilian tracks in the Coal measures of Pennsylvania. | The 
specimen is in the collection of the Western University
