122 HAY—VERTEBRATES OF CARBONIFEROUS AGE. [March 16, 
posterior thirds. While the specimen in my hands does not testify 
on these points as distinctly as one might wish, it seems probable 
. that Prof. Cope was correct. Between these sutures would lie the 
frontals, probably, but not certainly, distinct from each other. In 
front of each eye is a curved prefrontal. Behind the frontals come 
the parietals, probably separated from each other by sutures. Near 
the coronal suture is seen the circular parietal foramen. Behind 
the eye lies a relatively large bone, which probably represents both 
the postfrontal and postorbital. Jugal, supratemporal, squamosal 
and epiotic appear to be clearly distinguishable, the latter extend- 
ing prominently backward. The upper eyelid appears to have been 
strengthened by a pavement of bony plates over the eyeball, and 
near the free border this seems to have been produced into a kind 
of horn. ‘The eyes must have been very large. Prof. Cope has rep- 
resented a row of fourteen plates over the eyeball, which he re- 
garded as bordering the lid. It is more probable that they are 
sclerotic plates. Ido not find them. That author also describes 
and figures a whorl of scales on each side of the posterior region of 
the skull. I have seen no traces of these. ‘The jaws were provided 
with numerous small conical teeth, but they are not in such a con 
dition that I can say more about them. 
The left forearm is apparently in its proper place. The humerus 
and one bone of the forearm are present. These are followed by 
numerous small bones, considerably disturbed, which I take to be 
those of the hand. What appears to be a distal phalangeal bone is 
relatively large and ends in a point. I cannot determine the 
number of digits. The head of the humerus lies against and 
laterad of the impression of a bone which I regard as the scapula. 
It is 4 mm. long and one-half as wide and with a border which is 
concave on the side next to the head of the humerus. This bone 
approaches closely the notch in the back of the skull. 
Lying behind the angle of the jaw and running parallel with the 
body is a slender bone apparently consisting of two segments ; this 
I take to be a part of the hyoidean apparatus. 
The hinder limb is tolerably well preserved. The tibia and 
fibula are about two-thirds as long as the femur and they have a 
wide space between their shafts. Their distal ends are consider- 
ably expanded. There were five digits. No tarsal bones are seen ; 
the first digit seems to have been very short, the next one very long. 
The terminal phalange of this ends in a sharp point. The terminal
