and not channelled; and the tail terminates ina round 
blunt knob without caudal filaments. The feet are 
rather small, but are rendered unusually distinct from 
the peculiar manner in which the rings or divisions of 
the body are interrupted by the channel running along 
the centre of the body. It tapers very gradually, and 
almost imperceptibly for some time, from the head to 
the tail— Hab. Esquimalt Harbour, Vancouver Island.

This annelide is about 4 inches in length, exclusive 
of the proboscis, which, where exserted, is 3ths of an 
inch long, and is about 3 lines in breadth ; the proboscis 
is 4 lines at its greatest diameter. The head is rather 
short and conical, and strongly ringed. The antenne 
are somewhat broad. The feet are broad, composed of . 
two lobes, and are destitute of branchial filaments. The 
bristles are jointed, and the setz straight and sharp. 
The segments of the body are very numerous, composed 
of a double ring, the one on which the feet are set being 
the narrower of the two, and raised; while the whole 
surface of the body, especially on the upper side, is 
densely, though not very strongly, corrugated throughout 
its whole length. The proboscis is densely scabrous, 
and covered with very short dark-coloured bristles. 
The body tapers to a narrow point posteriorly, and 
terminates in a loosely-connected short lobe, armed at 
the extremity with a slightly-curved, horny, sharp- 
pointed claw.—Hab. Esquimalt Harbour, Vancouver 
Island. (Brit. Mus. Col.)
