River.

Captain Stokes has furnished me with the following note on this species.

"Length in feet inches:
of Alligator: 15 0.
From base of head to extremity of nose: 2 2.
Across the base of head: 2 0.
Iength of lower jaw: 2 0.

Teeth in both jaws vary in size, and are variously disposed, as will be
seen in the sketch.

In upper jaw on each side of maxillary bone: 18 2 incisors.

In lower jaw on each side of maxillary bone: 15 2 incisors.

The largest teeth are 1 1/2 inch in length. The two lower incisors are
stronger and longer than the upper, and project through two holes in
front part of upper jaw. Breadth across the animal from extreme of one
fore foot, across the shoulders, to the other side, 5 feet 2 inches. The
fore feet have each five perfect toes, the three inner or first, have
long horny nails, slightly curved, the two outer toes have no nails, nor
are they webbed. The third and fourth toes are deeply webbed, allowing a
wide space between them, which is apparent, even in their passive state.
The hind feet are twice the size and breadth of the fore, with four long
toes, the two first are webbed as far as the first joint, and the other
are strongly webbed to the apex of last joint; the last or outer toe has
no nail. From the apex of tail, a central highly notched ridge runs up
about midway of it, and there splitting into two branches, passes up on
each side of the spine over the back, as far up as the shoulders,
gradually diminishing in height to the termination. A central ridge runs
down from the nape of the neck, over the spinous processes of the
vertebrae (being firmly attached to them by strong ligaments) as far down
as the sacrum, diminishing to its termination likewise."

The eggs are oblong, 3 inches and 3 lines long, and 2 inches 8 lines in
diameter.

The skull of this specimen, which was presented to the British Museum by
Captain Stokes, has exactly the same form and proportions as that of the
crocodiles called Goa and Muggar on the Indian continent, and is quite
distinct in the characters from the Egyptian species.

A number of large stones, about the size (the largest) of a man's fist,
were found in the stomach.

Messrs. Dumeril and Bibron deny that any species of crocodile is found in
Australia. See Erpet. Gen. 1 1836, 45.
