Body from half to three quarters of an inch long, rather gibbous, broadish and truncated
in front, swelling in the centre, and tapering to an obtuse point behind. The back and sides
are covered with soft elevated tubercles, conical at the base, and expanded, flattened, and
mammillated at the top, in the centre of which there is a reddish spot. These tubercles-are
disposed somewhat symmetrically :—a crest of two or three, united into a line, runs between
the tentacles, before which there are three large ones, and behind this line a row extends
along each side of the ridge of the back to the branchiae. Three much larger than the rest,
and branched, surround the branchiae in front, and a line of tubercles also runs along the
posterior ridge to the tail. On the sides they are disposed in lines; one of which on each
side, more distinct than the rest, runs from the sides- of the veil to the posterior ridge behind
the branchiae, forming a subpallial margin. The whole of the body, with the exception of the
areas afterwards mentioned, is of a purplish-fawn colour, occasionally inclined to a rosy
hue, sprinkled over with very minute white spots, interspersed with larger ones of a dark
brown colour approaching to black; there are a few whitish blotches near the tentacles,
and a streak of opake white on the back, immediately in front of the branchiae. The
sides of the foot are. marked with darkish radiating lines of the- same colour as the
body. Between the tubercles there are placed symmetrically over the body smooth
areas of a rich velvety brown, with a brilliant greenish-blue spot of gem-like lustre in
the centre of each. These areas are studded round with dark chocolate brown or black
spots; they are of different sizes, and placed as follows:—there are two on each side,
sipping diagonally outwards before the tentacles, behind them are other two sloping backwards
towards the sides, and further back ‘a large oval or lozenge-shaped one .on the centre of the
back, and one or two small ones behind, with others at the sides. Two large irregular areas
are situated on each side before the branchiae, and a very large heart-shaped central one
