The fur and hair upon the belly is longer than that upon the
back.
Externally there is no appearance of the organs of generation in either
sex; the orifice of the anus being a common opening to the rectum and
prepuce in the male, and to the rectum and vagina in the female.
There was no appearance that could be detected, of nipples; although the
skin on the belly of the female was examined with the utmost accuracy for
that purpose.
The head is rather compressed. The bill, which projects beyond the mouth,
in its appearance resembles that of the duck; but is in its structure
more like that of the spoonbill, the middle part being composed of bone,
as in that bird: it has a very strong cuticular covering.
The nostrils are two orifices, very close to each other, near the end of
the bill; the upper lip projecting three quarters of an inch beyond them.
The eyes are very small; they are situated more upon the upper part of
the head than is usual, and are directly behind the loose edge of the
cuticular flap belonging to the bill.
