OF THE ‘PORCUPINE’ EXPEDITIONS, 401 
The head is at once distinguished from the previous form by the large size of the 
eyes, both anterior and posterior. The palpi have minute papille. The scales are fur- 
nished with the same sparsely distributed clavate papilla, but differ in having a close 
array of short acicular spines (which are much more numerous than represented by Prof. 
Sars) scattered over the surface. The ventral cirri have short clavate papille. 
The dorsal bristles are slightly yellowish, and, though as conspicuous in size as those 
of A. jinmarchica, are much less acutely tapered at the tip, and have closer rows of 
spines. The contour and curves also diverge. The superior ventral bristles have 
slightly shorter tips than in A. finmarchica; and the rows of spines are not so distinctly 
separated. The tip is similar, viz. slightly hooked; but the spines become so elongated 
toward the tip that they stand out on each side like a series of filaments (Pl. LX XII. 
fig. 5, and the same bristle more highly magnified in fig. 4, the specimen being from 
the middle of the foot). 
PHYLLANTINO“ MOLLIS, n. s. Dredged in 539 fathoms in the Atlantic, 1870. The 
fragmentary specimen measured about # inch. ‘There are about forty segments besides 
head and tail. The whole body is soft and delicate; and very few bristles were found 
in any of the feet. ‘The dorsum has a brownish colour throughout; and the pigment 
posteriorly is somewhat regularly disposed in the segments. The body is character- 
istically elongated, and tapers much posteriorly. The head differs from most of its 
allies in the very large size and situation of the eyes. ‘The posterior pair lie quite at 
the posterior border; the anterior, which are about twice as large as the former, occupy 
the lateral region of the cephalic prominence. The pairs are comparatively close to 
each other, and appear to have lenses. The median fissure for the tentacle is deeply 
marked, and almost splits the head into halves. No scales were present. 
The structure of the feet could not be fully made out from the condition of the spe- 
cimen; but they seem to differ considerably from the ordinary types. Anteriorly the 
dorsal division is much elevated in many as a soft process, probably for the attach- 
meut of the scale; while the ventral branch posteriorly projects as a long soft lobule. 
The dorsal bristles (P1. LX-XII. fig. 5) are short and stout, very translucent, considerably 
curved, and with prominent rows of spines. The specimen figured is one of the largest 
and least curved. There isa smooth portion at the tip. The ventral bristles (Pl. LX XII. 
fig. 6) are extremely slender and translucent, both as regards shaft and tip. The latter 
is long and tapered, and ends in a slender point, which in some is slightly bent. The 
spinous rows haye the usual arrangement, and disappear before reaching the extremity. 
There is no form which appears to resemble this species. 
LEPIDASTHENIA BLAINVILLU, Aud. & Ed. Dredged in 45 fathoms, eight miles off 
Cape Sagres, in 1870. An elongated form with distinct characters. The colours have, 
for the most part, disappeared; but the dorsum is still somewhat brownish along the
