and not channelled ; and the tail terminates in a 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. Hob. Esquimalt Harbour, Vancouver Island.

This annelide is about 4 inches in length, exclusive 

 of the proboscis, which, where exserted, is -Jths 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 antennae 

 are somewhat broad. The feet are broad, composed of 

 two lobes, and are destitute of branchial filaments. The 

 bristles are jointed, and the seta3 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.}
