A large example at my hand measures 47 mm. in length, 

 20 mm. in transverse diameter at the widest part, consisting of 42 

 segments, and with 15 pairs of elytra. The posterior region of 

 body, which as usual in the group is distinctly narrowed, bearing 

 a proportionally larger number of segments. 



Dorsal felt extremely tough and dense, and coated with 

 grayish mud. The long and abundant lateral hairs give the worm 

 a woolly aspect, and their colour is of delicate green. 



Prostomium roundish, having a front a short blunt conical 

 tentacle, immediately behind which are 2 pairs of eyes, the anterior 

 pair being wider apart than the posterior. They are small but 

 distinct black points, entirely sessile. 



A series of light bronz- coloured great setae (or spines) are 

 found projecting outwards amongst the hairs. The tips of these 

 setae do not taper much, but end in somewhat broad points (fig. 

 4), which are covered with minute chitinous spikes, so that the 

 surface is rasp-like. The inner tufts of setae, which curve r(3und 

 and backward amongst the felt of the dorsum, are broad at the 

 base but tapers to slender tip, also marked by slight roughness 

 or points. The ventral setae anteriorly are for the most part 

 (fig. 5) dart-shaped, but in some the tip is entire (fig. ö). 



Dorsal cirri long and finely tapered toward the tip, which is 

 slightly clavate.
