248 Dr. Schreibers s Description of 
direction is towards the body, almost parallel to it ; and, upon 
removing them, the branchial apertures are seen directed to, 
and communicating with, the mouth, like the gills in fishes. 
Each of these apertures is divided by three thin simple mem- 
branes, (not vascular, as in fishes,) attached in like manner to 
three oblique cartilaginous bones, but leaving only two holes 
between them ; in which circumstance, and in the red colour 
of the appendages during life, this animal differs materially 
from fishes, and from tadpoles or other larvae. 
Behind the appendages, the head becomes narrower, and 
forms a round neck, reaching from thence to the insertion of 
the fore feet, about half an inch long, and a little narrower than 
the body. 
The body itself is round, equally thick throughout, and, from 
the insertion of the fore feet to that of the hind feet, about 61 - 
inches long. The fore feet are about one inch long, consisting 
of the thigh and leg, and terminating in three toes, without 
nails, whereof the middle one is the longest. The hind feet 
are about one-sixth of an inch shorter than the fore feet ; and 
terminate in only two ill shaped toes. 
Behind these feet, the body grows narrower, and terminates 
in the tail, which is three inches and a half long, compressed on 
the sides, and very fleshy and strong in the middle; it grows 
narrower towards its end, which is almost pointed, and, as well 
as the edge above and underneath, is surrounded by a thin 
membrane, which gives it a considerable breadth. Under- 
neath, rather lower than the hind feet, is the anus, an oblong 
aperture, surrounded by a strong wrinkled sphincter. 
Upon opening the body by a longitudinal section, from the 
anus to the edge of the under jaw, I found the whole cavity
