T. with seventeen pairs of exserted fasciculi and eight dorsal 
plates. 
Body long, with - numerous. articulations furnished de whole 
length with peduncles, and a few with fasciculate bristles; but 
the seventeen anterior joints have the fasciculi most conspi- 
cuous, being always erected, and remaining so after death: 
the first eight joints have a broad plate on the back different 
in structure from the rest; they are of a rufous-brown colour, 
shaded with purplish-black, continuing down the back in a de- - 
creasing line. The general colour of the other parts is yellow- 
ish. Beyond the seventeen first joints the peduncles are very 
small, and appear to be destitute of fasciculi ; and they incline 
gradually from the sides to the back, till towards the extremity 
they almost meet, forming two dorsal lines: near the mouth 
originate numerous capillary appendages, that are five or six 
earo inches
