rich broad red line ; adjoining this is a whitish space, and 

 carried round the mantle, near the body, is a still more bril- 

 liant blood red line, with internal club-shaped prolongations 

 of the same beautiful purple red colour. Interspace and for 

 about \ inch of breadth of the back, the mantle is again 

 whitish, with shades of purple and yellow nearer the beauti- 

 fully mottled back. The underside of mantle has also a 

 broad white edge, the rest brilliantly variegated with dotted 

 purple, yellow, and red splashes. Branchise 7 or 8, large, 

 branched ; each rising from a separate cavity in a circle about 

 half an inch from a protruding yellow coloured anal orifice. 

 Plumes roseus, with red midribs. Dorsal tentacles large, 

 clavate; apex pointed, slightly truncated, on inner edge lami- 

 nated ; colour pinkish and spotted yellow ; ridge of cavity 

 spotted with yellow and red. Head large, protruding nearly 

 j inch from mantle. Mouth near foot, situated in the centre 

 of an oval projection, and on each side is a long broad toothed 

 leaflet or oral appendage, red and dotted like the head. 

 Foot long, broad, with parallel sides, rounded and trans-

 nymph I have ever seen, and none but a good artist could do

 is best seen when the animal is swimming, and reflecting in

 on which is placed a broad circle of rosy coloured feathery 

 tufts. The live specimen, of which the above is but a faint 

 description, was found under corals in low water near Fort 

 Frederick. In another specimen from the same locality, the 

 white edge of the mantle was replaced by a rich crimson red, 

 which coalesced with the inner red line, leaving a faint white
