a dark bar at the base, then a pale region with another bar below the filiform tip. If
colour is to be relied on, thé pale part would be homologous with the slightly swollen
region in other forms. The tentacular cirri are similar to the median tentacle. All these
cirri have the slightly enlarged part pale, with a brown band on each side, and the
column below is brownish. The palpi show minute papillae-like serrations along the
sides under a high power, probably partly due to the rigid contraction. They thus
differ materially from those of HarmotJioe imbricata with the minute clavate cilia.
The Body is narrower than in HarmotJioe imbricata, and the line of bristles on each
side is straight and trim; moreovèr, it has a general firmness which is characteristic.
The anterior end diminishes from the eighth or ninth bristled segment towards the head,
while posteriorly the diminution, which is gradual, begins shortly behind the middle, and

the body terminates in a process bearing the two caudal cirri beneath the vent. The
number of bristled segments is about forty-two. Dorsally the latter are marked from
the head backward by a median series of brownish touches, which posteriorly show a
somewhat symmetrical arrangement in the centre of each segment, consisting of an
anterior, narrow, curved bar, a fan-shaped region divided by a median streak and a short
transverse bar posteriorly. A prominent dark patch also occurs on the papilla (homo-
logue of .scale-papilla) and a little pigment at the base of the dorsal bristles. The ventral
surface is pale and iridescent; the nephridial papilla is smaller than in HarmotJioe imbricata,
and passes into the fissure between the feet. A considerable portion of the tail is devoid
of scales, and it is this region which has the pigment on the dorsum best developed.
The segmental (nephridial) papilla commences on the sixth foot, and extends to the
posterior feet as a very minute process.
Proboscis.—The extruded proboscis (Fig. 23) has the usual teeth, the lower pair biting
to.the right of the upper, nine flattened conical papillae dorsally, and nine ventrally at the
margin. The skin-folds at the mouth are marked by brownish pigment. The pre-gastric
c»ca are short and small. The ventral alone.is conspicuous in the preparations, for the
second proceeds little beyond the stomach, and the third is nearly transverse.
Scales (Plate XXXII, fig. 5)—fifteen pairs. First pair rounded, the others reni-
form or ovate-reniform, the last pair being ovoid, of a brownish-red colour, or sometimes
slightly purplish marbled with grey. They generally show a pale area over the scar for
the pedicle, and from the depth of the colour this is best marked anteriorly, the pigment
in the posterior scales being broken up into a series of touches and granules. The
entire surface, with the exception of a small area at the anterior and inner border, is
densely covered with minute spines, which are longest towards the outer border. The
posterior edge, again, has just within the margin a series of soft globular papillae
arranged at intervals and visible under a lens. Some are slightly clavate in outline,
while the tip in others is truncate or slightly nodular. They are few in number on the
last scales. A few short slender cilia occur at the outer or posterior margin. The
under surface is iridescent, and the scar for the pedicle is near the hilus or indentation,
where it is present, on the outer .border. The first pair of scales have a few short cilia
on the inner border, and a well-marked series of clavate cilia on the outer and anterior
margin. The large globular papillae on these are from four to six in number. A variety
procured by the ‘ Knight Errant * at Station 2 (1882) is pale, with few and small tubercles
on the posterior border of the scales.
Feet.—The first foot has two dorsal bristles, one curved and less pointed, the other
straighter and more acute. The spinous rows are more distinct than in the typical foot.
The tip in both is minute.
The second foot has a dense tuft of dorsal bristles, generally more curved and with
more distinct spinous rows than in the typical foot, and the bare portion at the tip is
proportionally broader and better marked. The slender ventral bristles have rows of
long spitzes and simple tips, those at the ventral edge of the series approaching the
pinnate type seen in other forms. They do not project beyond the dorsal bristles.
The third foot has the dorsal bristles less curved and the tips more acute. In the
ventral division the bristles have increased in strength, and, while the upper and lower
series have simple tips, the rest have the secondary spur. The tip of the smooth ventral
cirrus is long and filiform.
In the fourth foot the ventral bristles have become more prominent by the increase
of the fleshy part of the foot, and some simple tips still occur superiorly, and a more
numerous series inferiorly. The spinous rows are long. The dorsal bristles are
elongating, the long outer ones having acute tips, the inner broader smooth tips.
In the typical foot the dorsal division has long and very slightly curved bristles with
gently tapered acute tips throughout, the sharpest tips as usual being external (on a slide
next the ventral). They are thus easily distinguished from those of HarmotJioe imbricata,
and also by the much closer spinous rows. Bristles of the same length are decidedly
mpre slender than in H. imbricata. One of the longer forms is represented in Plate
XXXVIII, fig. 2. The tip tapers to a smooth, blunt point, and immediately below the
latter very fine and close spinous rows occur. A glance at the latter in rapidly examining
specimens is one of the most satisfactory points in discrimination. The ventral division
bears superiorly a series (Plate XXXVIII, fig. 1) with long spinous extremities, more
slender and with longer spinous rows than in H. imbricata. In a few the smooth tips
have no secondary process. The next series has a small secondary process, and the
spinous border gradually diminishes in length. The bifid tip differs from that of
H. imbricata, especially in regard to the minute size of the secondary process. Inferiorly
the tips are again simple. Posteriorly the structure of the dorsal bristles remains
nearly the same, but the ventral become attenuate, the bifid tip being visible, but the
secondary process is minute. The dorsal cirri have a dark bar above and below the
