The Laminarian region. It is generally found in old univalve shells (viz. Fusus antiquus, Bucciiium undatum, aud Fusus cor- neus) ; and it occupies the shell in common with the Hermit- lobster. Besc. Body from 3 to 4 inches long, ^ths or |th broad, semi- cylindrical, tapered towards the tail, of a tile-red colour, marked along the back with two snow-white lines, the narrow space between them being of a fine dark red colour, glossed with a pearly purple lustre, more especially on the ventral surface. Head small, the front as usual pointed with two conical antennae longer than its own diameter, and furnished at each side with a large biarticulate palpus. Eyes four, black, and very distinct. Mouth inferior. The proboscis roughened with black prickles. Jaws falcate, rather small and slender, corneous, crenulate on the inner edge; the crenulatious four or five, and not deep ; the brown curved extremity plain. Tenta- cular cirri four on each side, setaceous, of unequal lengths. Seg- ments 118, very narrow, the first broader than the following, but not equal in breadth to two united, convex dorsally, smooth. Feet No. XXX.—Nereilepas uniform, the superior cirrus elongate, surpassing the dorsal bran- chial ? papilla, which is more prominent and much larger than the others (No. XXX.). Bristles of the upper tubercle few, those of the lower bifasciculate, two-jointed, the apical joint smooth, often broken away from the lowermost bristles. Spines brown, acute; ventral surface flat. Tail with two short styles. When macerated in spirits, the lines and red colour are com- pletely remove
