Aud. and Edw. Litt. de la France, ii. p. 188. /lab. Down Coast, Wm. Thompson, Esq. The single specimen in the collection was about 5 inches in length and as thick as a large swan's quill: the colour was a blueish gray with a pearly lustre, but the feet were a dusky reddish brown, and this colour had tinted the posterior half of the body. Head small, the palpi projecting beyond the antennae: proboscis armed as usual ; the jaws slender with dark brown apices, serrulated along the whole falcate cutting edge : tentacular cirri not longer than the breadth of the post- occipital segment, which is nearly of the same size as the one behind. Segments about 90, with well-developed feet, which are more distinctly stalked than usual, and their lobes are very obliquely placed in relation to each other. The dorsal lobe of all the feet is largest, humped, and furnished with a cirrus hanging far beyond its apex; but on the middle and posterior feet this lobe becomes greatly larger, and is raised abruptly into a large hump, in front of which the cirrus originates. On the posterior extremity the hump advances, so to speak, on the foot, and leaves only a small papillary apex, over which the long cirrus hangs. The inferior cirrus is longer than its lobe. The spines and bristles present no peculiarity. ** Feet dissimilar, the posterior with foliaceous lamella. 7.
