GASTEROPODA. 279 
ANIMAL with a very large, muscular, oblong-oval foot, broad and 
nearly right-angled in front, narrowing behind, the surface divided 
into oblong protuberances by radiating and concentric furrows. 
Colour above brownish-purple, thickly dotted with small chocolate- 
coloured spots; beneath yellowish-brown. Head long, compressed, 
having on each side a projecting lobe narrowing towards the neck. 
Near the upper margin of these lobes are the eyes, like two obscure, 
dull-black points. Just inside of the eyes originate the tentacles, 
which are short, acutely conical; a fissure extends from their base to 
the margin of the cervical mass, separating the lateral and inferior 
lobes from the frontal one; the whole of this part is lighter-coloured 
than the foot. Siphon nearly two inches long, cylindrical, very thick 
and muscular, with short triangular processes at the base on each side, 
spreading out upon the head when the animal is extended. 
Only a single specimen was found, at Burnt Island, in Orange 
Harbour, on sandy bottom. It was very sluggish, and during the 
three weeks that it was kept alive, it extended itself but once. It 
secreted abundance of clear, glairy fluid, like white of eggs. [J. Pp. c.]

ANiMAL deep orange near the margin, soon blending into a broad 
zone of rich crimson, which again passes into deep orange; over the 
whole surface are dispersed numerous small tubercles of bright yellow, 
larger and more apparent on the crimson zone than elsewhere ; under 
side of foot pale orange. Foot nearly smooth, broad-oval, and when 
fully expanded, extending far beyond the shell in all directions, except 
posteriorly, where it does not quite reach the apex of the shell. Head 
broader than long, much compressed, forming three sub-equal lobes, 
of which the central one is emarginate. Tentacles short, conical, 
obtuse, arising a short distance from the margin at the anterior third 
of the cervical mass; at a short distance behind, and near the margin 
are the eyes, which are small, black, and seated in a circular depres-
