Two New Species of Fossil Footmarks. 55 
. Remarks.—It may be that what I have reckoned as the first 
phalangeal impression on the two inner toes was made by meta- 
Otozoum Moodii. (Fig. 1, A.) 
_ Divarication of the outer toes, 35°; do. of the inner and sec- 
ond toe, 15°; do. of the outer and third toe, 12°; do. of the two 
middle toes, 5°. Length of the inner toe, 8°5 inches; do. of the 
second toe, 10:25 inches; do. of the third toe, 8 inches; do. of 
the outer toe, 8-5 inches; do. of the foot, 20 inches; do. of the 
step, about three feet. Distance between the extremities of the 
outer toes, 13 inches. Width of the foot behind the phalanges 
and metacarpus, 5 inches; do. of the toes, from 2 to 3°25 inches. 
Length of the phalanges of the inner toe :—proximal phalanx, 3 
inches; of the second, 2 inches; of the third, 3-4 inches (?) do. 
of the second toe :—proximal, 2-4 inches ; second, 2°5 inches ; of 
the third, 2-9 inches; do. of the fourth, 2°6 inches (?) ; do. of the 
proximal metacarpal bone of the third and fourth toes, 3°5 inch- 
es; of the second, 4 inches: of the first phalanx of the third toe, 
2 inches; of the second, 2 inches; of the distal, 3°8 inches (?); 
do. of the outer toe :—proximal, 1-6 inch; of the second, 1:6 
inch; of the distal, 5-4 inches (?) Divarication of the axes of 
the feet, 30°. Distance to the right and left of the middle of the 
heel, from the average line of direction along which the animal 
moved, 2:5 inches. Integuments of the bottom of the foot, ru- 
gose and irregular illose. 
Distinctive Thatch cok oat thick toes directed forward and 
is entire enough for description, I should have suspected some 
deception in both these characteristics ; but sufficient remains 
Situation and character of the Deposits containing these 
tracks.—The tracks above described are all in relief, and the 
tock is a very coarse gray sandstone, the grains being often as 
large as buckshot. Yet every thing is exhibited most distinctly. 
exhibited, and shown upon the drawing, fig. 1. The tracks appear 
to have been made upon a fine micaceous sand, which has little 
more coherence now than when the animals trod upon it. But 
the coarse material that was subsequently brought over this fine
