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 branchise, 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, 

 sloping 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
