The mantle, in this Doris, reaches down to the foot on all sides,
and covers the head, and is not furnished with any appendages.
The tentacles, which are plated, as in the Triope, pierce through
the mantle, and are sheathed; the gill plumes are large and ample
feather-like organs, eight in number, forming a complete circle
round the orifice, in the manner of a beautiful expanded flower.
As the Doris crawls along, it now and then lifts and puckers the edge
of the mantle, and displays its under surface and that of the foot,
which are of a rich orange-scarlet hue.
