with a black semicircular patch on the inner edge. 
They do not overlap each other except near the head. 
On the body of the animal they are wide apart, leaving 
the centre of the back exposed. The proboscis is large 
and wrinkled, and the jaws are of a reddish-brown 
colout. The antenne are five in number, the central 
one being nearly three times as long as the external 
pair, and of a pure white colour; the internal and ex- 
ternal pairs white, tinged with black. The feet are very 
prominent, strong, rounded, conical, and armed with 
seven or eight stout brown bristles. The second branch 
is extremely small, and sends off two or three very small 
white sete. The superior cirrus is tolerably long and 
sharp-pointed; it is pedunculated, the peduncle being 
stout, conical, and of a deep black colour. The inferior 
cirrus is short, conical, and sharp-pointed. The last 
segment of the body is terminated by two tolerably 
stout but not long cirri— Hab. Esquimalt Harbour,

This species is about three inches long, and rather 
more than one-third of an inch in diameter at the 
broadest part of the body. It tapers gradually from 
the head to the tail, which is only about one-eighth of 
an inch broad. The colour is of a light brown, a broad 
line of a much darker brown running along the whole 
length of the centre of the back. On the surface a 
groove runs down the centre of the body throughout its 
entire length. The elytra are 35 pairsin number, thin, 
membranous, and of a light brown colour. The two first 
overlap each other slightly in the middle; but for the
