286 ‘Notice of a New Speeres of Salamander. 
anteriorly, in form and structure resembling those of the 4. 
_ palustris (nob.),* but in proportion are exceedingly small 
and slender, being very little larger than those of the com- 
mon mouse—in an animal 7 inches in length of body, and 
nearly 6 inches in girth, the forelegs measure less than one 
inch and a half to the extremity of the nails; the latter 
are black ,compressed, sharp, and hooked as in the squirrel. 
Habit. According to Mr. J. J. Audubon, (to whom I am 
indebted for this specimen,) this animal never burrows, but 
conceals itself in hollow trees, generally forming a hole in 
the side, somewhat after the manner of the woodpecker, 
where they retreat in case of emergency. They inhabit the 
cotton fields exclusively ; carry their young on their back, 
and, with their family thus secured, climb dead trees as 
nimbly as the squirrel. 
Inhabit the borders of the Mississippi—the present speci- 
men from Beech woods near Natchez. 
On the whole, the present species bears a near resemblance 
to the Arvicola hortensis, but is sufficiently distinguished by 
the extreme proportional minuteness of the fore legs and feet, 
by the colour of the fur, as also in size and inthe tapering form 
of the body at the root of the tail, the manners of the animal, 
&c;
