ated to be an otter.
This cut, which can scarcely be distinguished from one given by Stevens
(Fig. 66), is here reproduced (Fig. 6), together with the second
supposed manatee of the latter writer (Fig. 7).

To afford a means of comparison, Fig. 154, from the "Ancient Monuments"
of Squier and Davis, is introduced (Fig. 8). The same figure is also to
be found in Wilson's Prehistoric Man, vol. i, p. 476, Fig. 22. Another
of the supposed lamantins, Fig. 9, is taken from Squier's article in the
Transactions of the American Ethnological Society, vol. ii, p. 188. A
bad print of the same wood-cut appears as Fig. 153, p. 251, of the
"Ancient Monuments."

It should be noted that the physiognomy of Fig. 6, above given, although
unquestionably of an otter, agrees more closely with the several
so-called manatees, which are represented without fishes, than with the
fish-bearing otter, first mentioned, Fig. 4.

Fig. 6 thus serves as a connecting link in the series, uniting the
unmistakable otter, with the fish in its mouth, to the more clumsily
executed and less readily recognized carvings of the same animal.

It was doubtless the general resemblance which the several specimens of
the otters and the so-called manatees bear to each other that led
Stevens astray. They are by no means facsimiles one of the other. On the
contrary, while no two are just alike, the differences are perhaps not
greater than is to be expected when it is considered that they doubtless
embody the conceptions of different artists, whose knowledge of the
animal, as well as whose skill in carving, would naturally differ
widely. Recognizing the general likeness, Stevens perhaps felt that what
one was all were. In this, at least, he is probably correct, and the
following reasons are deemed sufficient to show that, whether the
several sculptures figured by one and another author are otters or not,
as here maintained, they most assuredly are not manatees. The most
important character possessed by the sculptures, which is not found in
the manatee, is an external ear. In this particular they all agree. Now,
the manatee has not the slightest trace of a pinna or external ear, a
small orifice, like a slit, representing that organ. To quote
