of sand, with the shells of Foraminifera, with spicules of 

 Alcyonaria and Sponges, with pieces of the shells of Echi- 

 noidea and Molluscs. The ventral side of the body is hairy, 

 on account of the presence of long, slender papillae, 

 especially in the vicinity of the mouth, that is almost 

 entirely hidden by them. The venter as well as the bristles 

 are of an ochreous hue. The first pair of elytra have an 

 elongated, elliptical shape, with a concave, wing-like lobe 

 at the anterior part of their median border; besides along 

 this lobe, the whole margin is beset with filiform papillae. 

 The right elytron somewhat overlaps the left one, but 

 they diverge with their anterior part, which makes the 

 tentacle and the bristles of the buccal segment visible. 

 The other scales are semi-circular, with a straight anterior 

 border and a conical lobe at their internal angle ; their 

 posterior margin is beset with filiform papillae, that are 

 the longest at the external side, where they are separated 

 in 3 or 4 groups by small cup-shaped papillae. The ce- 

 phalic lobe bears on its dorsal side a pair of distinct black 

 eyes, almost hidden under the nuchal fold and another pair 

 of larger ones beneath it. The tentacle has a distal part, 

 about twice as long as the basal one ; its tip is swollen 

 and extends about till the extremity of the bristles of the 

 first segment and the tentacular cirri. The basal part is 

 furnished on each side with a small semilunar wing. The 

 palps are slender, smooth, tapering distally and extending 

 nearly as far as the bristles of the second segment. The 

 neuropodium of the second segment has a club-shaped 

 prolongation ; jts bristles are articulated, with a very 

 slender process with curved tip. The dorsal cirrus of the 

 third segment has a short basal part and a long whip- 

 shaped terminal portion, that reaches as far as the palp. 

 In the neuropodium of the succeeding feet the central 

 bristles of the fascicle are furnished with a rather long, 

 not stout, bifurcated terminal process ; their shaft bears in 

 its distal portion a number of faint transverse ridges. The 

 superior bristles of this fascicle, that bear a more slender 

 appendix, have the shaft furnished with obvious transverse
