twice as long as the lateral antennae. The tentacular cirri, equal in length, nearly as long as 

 the palps. A broad nuchal collar with two papillae. The scales (PI. XMI, iïg. 4) do not over- 

 lap, but leave the middle of the dorsiim uncovered (in a smaller specimen froni Stat. 156, the 

 scales cover the dorsum entirely) ; they are auriculate with a conspicuous scar of attachment, 

 lying eccentrically in its posterior half, from which several branched nerve-stems are emerging. 

 The surface of each scale is smooth except a band along its border especially at the outer 

 side, that is covered with small knob-shaped papillae; the margin is without cilia. Both lobes 

 of the parapodia have an elongated triangular shape, and are nearly equal in length, enclosing 

 the acicula. However the notopodial fascicle is mach less developed than the neuropodial one 

 and consists of a dozen short, slightly curved bristles, with a smooth, blunt tip and faint, den- 

 sely crowded, circular ridges. The neuropodial setae (PI. X\'II, fig. 5) are about twice as long 

 as the notopodial ones, with a dilated subterminal part, that shows faint transverse rows and 

 a distinct secondary process beneath the tooth-Iike tip. The dorsal cirrus much longer than the 

 neuropodial fascicle ; the ventral cirrus two-thirds of the length of the neuropodial branch. 



The species is characterised by the situation of its eyes, its large scales without cilia 

 on the margin and its slender ventral bristles, without denticulated rows.

Head nearly as long as broad. Both pairs of eyes on its posterior half; the anterior 

 pair behind the lateral prominences of the head, the other one in front of its posterior mar- 

 gin. The frontal stalks of the lateral antennae like the basal part of the tentacle dark ; the 

 distal joint of the antennae twice as long as the head, with a black ring on the dilated part 

 beneath the filiform tip. The distal joint of the tentacle only a trifle longer. The palps stout 

 at the base, tapering distally. The scales (PI. XVII, fig. 7) touch each other in the median 

 dorsal line; they are elongate-oval, with a fringe of rather long filaments on their posterior 

 and on the greatest half of their internal and e.xternal border. Their surface is almost totallv 

 covered with red-coloured tubercles. Some of them in the area of the scar of attachment and 

 around it are large, globular or spinous ; those on the covered part of the elytron, in front 

 of the scar of attachment, are smaller, carinate, those on the region behind the ridge are small 

 and spinous. The anterior pair of elytra (PI. XVII, fig. 6) are elliptical and over half their 

 periphery are surrounded by stiff cilia nearly equal in length ; their surface shows round areolae, 

 from the centre of which a spine arises. Especially those in the midst of the scale are large, 

 while along the margin they have a cylindrical stem and a crown of three or more spinelets. 



The parapodia have the ventral lobe much stronger developed than the dorsal one; the 

 neuropodial bristles have a rudimentary tooth beneath the tip or this tooth is quite absent. On their 

 dilated subterminal part there are 4 or 5 laciniate fringes, faintly developed, with .some larger 

 teeth in the distal row. The notopodial bristles are slender, feeble, provided with densely crow- 

 ded, laciniate rows. The dorsal cirri have a black ring on the dilated subterminal part and
