dorsal bristles, and in the pale semi-translucent scales, but the ventral bristles approached
each other closely. A re-examination of all the characters and of Malmgren’s description
now inclines me to unite them, especially as in the generic characters he states that the
dorsal bristles are shorter and thicker than the ventral, while in the specific he says they
are much shorter and a little more slender than the inferior bristles. Moreover, if his
figure of the dorsal bristle be supposed to be that next the ventral series (always the
most slender and elongate), the distinctions more or less disappear. The only doubtful
point is the possible existence of a species agreeing in all respects with that from
Lochmaddy, but having more elongated dorsal bristles. Levinsen seems to be of the
same opinion.
Pew individuals of this form would seem to exist. Only a single example was
obtained at Lochmaddy, and one in the stomach of a cod at St. Andrews. Baron de St.
Joseph found one in the tube of Lanice conchilega at Dinard. With the two foregoing it
forms a special series closely approaching each other and such forms as the Polyno’e
crassipalpa of Marenzeller.
5. H aemothoe antilopis, McIntosh, 1876.
Specific Characters.—Length about three-quarters of an inch or a little more. Head
broad behind, peaks truncated in front, two widely separated eyes posteriorly, and a
larger pair laterally and below the short peaks, not visible from~the dorsum. Median
tentacle and tentacular and dorsal cirri moderately long, slightly enlarged below the
filiform tip, and covered with numerous cilia with slightly bulbous tips. Lateral
tentacles inferior. Palpi of average length—with clavate papilla). Body, moderately
elongated, of considerable breadth, bristled segments 33—35. Scales fifteen pairs,
mostly reniform, entirely covering the dorsum, with long cilia externally and
posteriorly and shorter on surface, which also has large horny papilla) ending in
spines with hispid tips. Dorsal bristles elongated, with' smooth tips and very
distinct spinous rows (resembling the horns of an antelope), ventral with bifid tips,
scarcely hooked, and in some the distal part of the spinous region is narrower than the
smooth tip. Ventral cirri rather slender and tapering, with short clavate cilia. The
segmental papilla) are but slightly marked.

Habitat.—First procured at Lochmaddy, North List, in 1865; off the Hebrides
(J. G. J .); on muddy sand at 173 fathoms, ‘Porcupine,’ 1869; ‘Porcupine,’ 1870, 576
fathoms, on the Channel slope ; 227 fathoms outside Gibraltar; and 358 fathoms in the
Atlantic. I t is included in the Mediterranean fauna also by Professors Marion and Carus.
Its range is thus extensive, but the numbers hitherto have been few, generally a single
example at each station.
Length from three quarters to nearly an inch.
Head (Plate XXVIII, fig. 13) somewhat broad behind, with the anterior angles
ending in very short peaks. Two comparatively large and somewhat widely separated
eyes occur near the posterior border. The larger anterior pair are not visible from the
dorsum, being situated laterally and below the truncated angles of the snout. In most
specimens in spirit the pigment of the eyes has become very faint. The median tentacle
is moderately long, slightly enlarged below the filiform extremity, and covered with
numerous cilia with very slightly enlarged tips. The lateral tentacles are inferior, have a
slight enlargement below the tip, and are also supplied with clavate cilia. The tentacular
cirri are similar to the median tentacle, the cilia being continued about a third up the
filiform termination. The palpi are of moderate length, with rows of minute clavate
papilla), which toward the termination are dilated and then constricted below the slightly
granular tip.
The body is moderately elongated, of considerable breadth, not much tapered
anteriorly and only a little more so posteriorly, and with the usual markings dorsally
and ventrally. Bristled segments from thirty-three to thirty-five. The segmental
papilla) do not appear to be produced as tubular processes, only the projecting “ boss ”
or elevation indicating this structure.
The scales (Plate XXXII, fig. 16) amount to fifteen pairs, and entirely cover the
dorsum. The first pair are more or less rounded, the rest reniform, the outer lobe being
larger than the inner. They are fringed on the outer and posterior borders as well as
studded over the surface with cilia, which become very long on the former border, and
the tips are slightly bulbous. They are often coated with a granular parasitic growth.
The horny papilla) or tubercles on the surface are large and boldly marked, the dilated
tips forming blunt processes or spines truncated at the tip, which is hispid with sharp
processes, and in favourable specimens they resemble a rosette of spikes. The appearance
is thus characteristic. A pale brownish coloration occurs on the dorsal surface
where the scales overlap, but otherwise they are pale with the exception of the minute
brownish spines. The under surface is smooth and iridescent.
Feet.—The first foot has a few short bristles of the normal dorsal type, and very
slightly curved. The second foot has a considerable tuft of short dorsal bristles, only
the inner being curved, those next the spine being more or less straight, with the well-
marked spinous rows from, which the name of the species is derived. The ventral series
of slender bristles has long spinous regions superiorly and shorter inferiorly. All have
simple tapering tips. These bristles are proportionally shorter and stouter than the
typical series. The bristles gradually elongate and the ventral series become bifid, so
that in the typical foot (Plate XXIX, fig. 14) the dorsal division carries a conspicuously
long and strong series, the inner bristles being shorter and more curved as well as more
abruptly pointed at the tip, which has a short smooth portion; while the outer and
inferior series are long, very gently tapered, and slightly curved, with a. short, conical,
bare portion terminally. All are distinctly marked by transverse spinous rows at rather
wide intervals, whence the name of the species, from the resemblance of these organs to
