B. F’. Mudge on Fossil Footmarks in Kansas. 175 
We could find no other track, or any other fossils at this 
locality. Yet it is most probable that they will be found in 
other places, as the deposit has a long extent in a northeasterly 
and southwesterly direction. 
e weathered state of the specimen prevents our giving an 
accurate description, such as is desirable for a full identification 
of the species. Still, there can be no doubt that they are new 
kinds of Ornithichnites. The slab contains four prints, two (A, B,) 
on the left hand by one animal, (?)—one (C) on the upper right 
hand by another, and the fourth print (D) indistinct, but proba- 
bly by a third bird. 
A partial description may be of some value, which we give as 
follows. Both are three-toed and leptodactylous. 
Species 1. Track number C.—Divarication of the lateral toes, 
65°; of the inner and middle toes, 35°; of the middle and outer 
toes, 85°; length of the inner toe, 3°75 inches; of the middle toe, 
5'1; of the outer toe, 3°75; of the foot, 5:5; distance between 
the tips of the lateral toes, 4-1; projection of the middle toe be- 
yond the others, 2:1. 
Species 2. Track number A.—Divarication of the lateral toes, 
65°; of the inner and middle toes, 35°; of the middle and outer 
toes, 35°; length of the inner toe, 2°6 inches; of the middle toe, 
3°55; of the outer toe, 3°1; of the foot, 3°75; distance between the 
tips of the lateral toes, 3°2; between the inner and middle toes, 
21; between the middle and outer toes, 2:2; projection of the 
inner toe beyond the others, 1:2 inches. f : 
Track number B appears to be the left foot of the bird which 
made No. A, as the angles and length of the toes are the same ; 
bat the position of the inner toe standing so far back of the 
Others throws some doubt upon it. Number D may be the 
track of still another species, or it may belong to species 1; itis 
So indistinct that we cannot decide on this point. 
€ give no name to either of the species, as we hope more 
perfect prints may yet be found, which will give fuller charac- 
teristics of the animals which made the tracks. There are no 
marks of the claws on either of the tracks. Nor could we fin 
ut four inches in thickness; it is not laminated, and shows 
Knows how difficult it frequently is to identify the order or
