The head of this species is small and entirely concealed by the 

 anterior scales and dorsal set?o. The mesial tentacle is small, 

 very slender, and has a slight enlargement near the extremity, 

 followed "by a thin tapering apical portion which again ends in a 

 very slight knob. The buccal tentacles are about twice the 

 length of the mesial, and of similar shape. The body consists of 

 39 segments, with 14 pairs of elytra. There are no barbed seta) 

 on the parapodia. The dorsal seta) are 15 to 23 in number in 

 each parapodium ; they are long, slightly arcuate, trigonous, with 

 a series of denticles ou each border, and are arranged in a 

 radiating manner round the apex of the notopodia, the inner 

 ones nearly meeting those of the opposite side across the back 

 In addition to the setae the notopodia are provided with a small 

 quantity of flax-like hair. The ventral seta) are four or five in 

 each parapodium, short, bifurcate near the tip, one branch being 

 very short. The ventral cirri are very small, with a scarcely 

 perceptible enlargement a little beyond the middle, followed by a 

 thin terminal portion. The dorsal cirri are larger than the ventral, 

 but of a similar form. The scales are delicate and colourless.

The body contains 35 segments bearing setoo. The head has a 

 very prominent facial tubercle covered with papillae ; the mesial 

 tentacle is broken off near the base, on each side of which is a 

 prominent subspherical eye. The buccal tentacles are extremely 

 long, about a fourth of the length of the body, tapering, non- 

 ciliated. The first pair of parapodia have a few hair-like setae ; 

 the ventral cirri of this segment are longer than the dorsal, about 

 ith of the length of the lateral tentacles, with a club-like apex ; 

 the dorsal cirri are slightly dilated near the apex, which is acute 

 The dorsal cirri of the remaining pairs of parapodia are very long, 

 as long as the breadth of the body, slightly dilated near the apex j
