40 = Fossil Footprints of a New Species of Quadruped. 
Arr. Vi—Fssil Footprints of a New Specics of Quadruped 
by James Deane. 
I HAVE hitherto described 
of Connecticut River, the ori- } 
gin of which may be referred 
with probability, to animals # 
represented by the Batrachian 
order of existing reptiles. 
These impressions are of di- 
versified character, and indi- § 
cate three distinct family types 
or groups, as explained ina 
pi number of this Jour- 
ee the third group, I a 
now to add a second or ne 
species ; it 1s represented By 
the annexed wood-cut, which 
species described in vol. in, 
ii ser., p. 70, and it is possible | 
that the impressions were pro- 
duced by a young individual. 
This elegant example was 
recently discovered at Tur- 
tains seven pairs of impres- 
sions, three of which are rep- 
resented by the drawing. It 
will be apparent that the ani- 
mal was of diminutive size 
and that it advanced by regu- 
lar strides and sunk deep at 
each step. "he regularity and 
number of the imprints, give 
a beautiful appearance to the 
fossil, yet the feet are not indi- 
vidually so perfect as to render 
their anatomical set i 
clear. There appear “how 
ESE en cnn greet
