Foot-Print from Conn. Valley. — Cnslvnan. 155 
In the specimen in hand the onthne of llie uelj of the foot 
is, as it were, silhoi\ettcd against the somewhat Hghter reddish- 
brown of the matrix. Tlie hne is as clear cut as though out- 
Hned with a sharp pencil. Even the notches of the sides are left 
distinctly showing. On page 29 of his khnology of Massachu- 
setts (1858), Edward Hitchcock gives tiie following statement 
concerning tracks showing webbed feet 
"Wlicn a web made an impression deep enough t<i 1)c manifest, it 
is certainly an important fact, and characterizes certain animals : but 
I have been surprised to find how seldom distinct evidence of such 
an appendage appears in the fossil tracks. Yet, on examining the 
tracks of such animals as the goose and the duck, I find that it is 
only in a favorable state of the mud that any distinct trace of the 
web is left. We have at length found some fossil specimens with 
webbed feet, as the Otozoum and the Uphepus [HyphepusJ. 
"I have still some doubt in respect to the former: but if there 
be no mistake, the web extended even beyond the pellets of the toes ; 
while in the Uphepus [Hyphepus] it probably reached to the extrem- 
ity of the claws on the lateral toes, but not on the middle toe." 
The specimen in hand can belong to neither of these two 
genera as it is distinctly tridactylous while they are both tetra- 
dactylous. The following genus is proposed for it : 
Otouphepus, Gen. Nov. 
(Derivation, i-'roc, a giant: JV"''/i a web: and -'"'c, a foot). 
Otouphepus magnificus sp. nov. 
Foot-print tridactylous, digits decidedly pachydactylous, 
connected by a web, incised between the digits. Impressions 
of the joints of the digits very indistinctly shown. Digits ter- 
minated by fairly sharp claws, the expansions however ex- 
tending beyond as the foot is placed flat upon its under surface. 
Total length 6.5 inches, length of outer toe 4.5 in., inner toe 
3.2 in., middle toe 4.5 in. From heel to tip of outer toe 4.5 in., 
to tip of inner toe 5 in., between tips of lateral toes 2>'b i"-- 
between inner and middle toes 3 in., between middle and outer 
toes 2.4 in., middle toe extends 2.2 in. beyond the lateral toes. 
Type in the Boston Society of Natural History no. 12857. 
Specimen from Gill, Massachusetts. Triassic. 
As the foot is placed flat, the web on the inner margin is 
spread out and the scallops distinctly seen. They are very 
similar to certain of the reptiles of the present time in this re- 
spect.
