with brown. Nearly parallel lines passed from these blades 
into the shafts, where they converged. The apparatus had 
been injured. In glancing along the sides the feet project 
evenly, forthe basal part forms (when looked at from above) 
a cylindrical process, the setigerous lobe forming the anterior 
or median region of the tip, whilst posteriorly is a short 
subulate papilla or lobe, sometimes probe-pointed, which is 
longest in the anterior feet. 
The bristles are translucent and brittle, so that compara- 
tively few remain on the specimen. The spines, of which 
there are four or more in the anterior feet, are also pale 
and translucent, the tips only being russet-brown. The 
dorsal bristles (Pl. XII. fig. 30) are slightly curved at the 
end of the shaft, the tip then dilating in the usual manner 
with its wings and tapering distally to a fine point, which in 
some is considerably prolonged. A few bristles, again, are 
of a more slender structure, dilating little at the end of the 
shaft, and being continued as a very attenuate hair-like 
tip (Pl. XII. fig. 31). 
The hooks are likewise translucent and appear to be absent 
from the most anterior feet, though, as mentioned, they 
might have been removed. ‘The shaft is curved backwards 
towards the tip and gradually dilates to the beginning of 
the neck of the hook, which (neck) is short (Pl. XII. fig. 32). 
The main fang in this region of the body is small, and the 
crown above it has several small teeth. 
The form is peculiar, and probably came from a con- 
siderable depth. 
Lumbriconeress brevipes, sp. n. 
Habitat. Dredged at Station 10, in 81 fathoms, off Cape 
Finisterre, in the ‘ Porcupine’ Expedition of 1870. A frag- 
ment of about 40 bristled segments. 
Head, as in other forms, conical, and with a median and 
two lateral grooves inferiorly. 
Body gently tapered in front, the first two segments 
broader than the succeeding, and the first only very little 
broader than the second. The trim condition of the feet is 
a feature of moment, for the small posterior lobe is scarcely 
noticeable. The bristles stand stiffly outwards beyond the 
line of the feet. 
Proboscis.—The maxille (woodcut, fig. 3) are curved in 
the usual manner and dark brownish. Posteriorly they are 
articulated to two processes which together form a broad 
spear-head, a constriction marking off the region near the
