opaque whitish granules extend distally from it. The thick 
end of the elongated pear-shaped parasite narrows to a 
chitinous proboscis, which is deeply inserted in the tissues of 
its host. 
Phyllodoce sp.? 
Habitat. Dredged in Gaspé Bay, Canada, 30 fathoms, 
1873, by Mr. Whiteaves. 
Head (in spirit) forming a blunt cone, with the four short 
_ subulate tentacles at the tip. The posterior margin of the 
head is cordate, with two lateral bosses. The eyes are of 
good size, though much smaller than those of P. oculata, 
Ehlers *, and are situated about the posterior third of the 
head and have lateral as well as dorsal vision. The tentacular 
cirri are of average length, the anterior dorsal arising just 
outside the lateral boss. 
Body. As only a fragment of the anterior region was 
procured, all that can be said is that the general structure is 
typical, the segments being boldly marked dorsally and 
ventrally, two transverse bars in each segment being present, 
and ventrally a median longitudinal groove. 
The foot (Pl. I. fig. 3) is characterized dorsally by a broad 
and somewhat irregular lanceolate lamella, which probably 
is considerably altered posteriorly. The setigerous region is 
slightly bifid, and bears a series of pale bristles, with the 
usual curve distally below the dilated end of the shaft, which 
is spinous along the edge and more minutely so on the 
surface. The terminal blade is long, finely tapered at the 
tip, and rather boldly serrated on the edge. 
The ventral lamella is irregularly lanceolate, with a 
pointed tip, which extends fully as far outward as the tip of 
the setigerous process. 
This species differs from Phyllodoce laminosa in the shape 
of the dorsal lamelle, for they are much less foliaceous ante- 
riorly, and the ventral lamelle do not project so much beyond 
the setigerous region. 
The tips of the bristles are also longer and more tapered, 
and in this respect they also differ from the P. fragilis of 
Webster f. 
It is no nearer P. grenlandica or other form. It differs 
from the P. oculata of Ehlers, also from the American waters, 
which has a dorsal lamella of similar shape anteriorly and 
spinose dilated ends to the shafts of the bristles, by the 
broader and shorter ventral lamelle.
