Characteristics. Brown or ash. A dusky band from the nostrils to the eyes. The white of 
the upper lip reaches almost to the insertion of the fore legs. Length one 
inch and a quarter. 
Description. Body symmetrical, somewhat elongated. Skin smooth, or at the most with 
slightly elevated papille. Head conic. Snout acute; its sides vertical, and giving it a pyra- 
midal form. Orbits somewhat elevated. Anterior feet short, four-toed. Hind legs long, 
five-toed, semi-palmate ; all with rounded pellets at their extremities. 
Color. Brownish or light ash above, changing to light green ; blotched, and lined with dusky 
stripes on the surface of the body in a very irregular manner. On the anterior part, more 
usually abbreviated longitudinal lines, and unequal sized blotches on its posterior portions. A 
dusky stripe extends from the nostrils to the eyes ; occasionally a large triangular dusky blotch 
between and behind the eyes. Thighs and legs barred with dusky. Beneath whitish. 
I have met with this species in the neighborhood of New-York, and supposed it at first to 
be distinct from the southern sguirella. From a careful comparison of our specimens with 
those in the Cabinet of the Lyceum deposited by Major Le Conte, the only observable dis- 
tinction was in the smaller size of the northern animal. After a rigorous comparison, Major 
Le Conte decided it to be identical with the southern species. I am under obligations to him 
for the drawing which illustrates this pretty little tree-toad. 
According to Major Le Conte, it inhabits under logs and bark of decaying trees. 
While these pages are passing through the press, Dr. Holbrook is engaged in publishing a 
second edition of his Herpetology. He is still of the opinion that the squirella is exclusively 
a southern species.
