about the length of the smooth portion at the tip, which is diagnostic of this form and
also of Evarne Normani.1 The present species differs from the latter, again, in the more
tapering extremities of these bristles, and in the closer rows of spines. The spinous tips
of the ventral series are somewhat longer than in E. impar, and in this respect approach
E. Normani.
In the typical foot the lower lobe is more pointed and the ventral cirrus longer than
in E. impary b o that it projects as far as the tip of the foot. The translucent dorsal
bristles (Fig. 31) are considerably longer and less curved than in the typical species, and
their rows of spines much closer, the latter character also distinguishing them from
E. Normani. The ventral bristles (Fig. 32) approach those of the latter species more
closely than those of Evarne Johnstoni, being somewhat shorter than those of E. Normani,
which, again, have stronger tips than those of E. Johnston/i.

No scales are present. In all probability they approach those of E. Normani.
By the lengthening of the tips of the ventral bristles and their general slenderness
this species and E. Johnstoni come near Antinoe and allied forms.

Genus XY.—A n t in o e , Kinberg, 1857.
Lateral tentacles arising under the base of the median tentacle ; cephalic lobe with
lateral peaks anteriorly. Palpi subulate, densely covered with minute papillao. Dorsal
bristles long and tapering, with well-marked spinous rows. Yentral bristles long and
slender, with elongated spinous regions and hair-like tips. Segmental papillee distinct
though not large.
This genus approaches Harmothoe.

Specific Characters.—Head about as long as broad, with two acute anterior peaks.
Two posterior eyes, nearer each other and smaller than the anterior, which are situated
within the dorsal margin of the widest part of the head, and considerably removed from
the anterior peaks. Median tentacle brownish, tapering, with a long filiform tip and
numerous long clavate cilia. Lateral tentacles with short clavate cilia. Palpi long and
tapering, with minute clavate papillse, often with processes on the blunt tips. Tentacular
cirri with very long slender tips and numerous clavate cilia of moderate length. Body
somewhat broad, most distinctly tapered posteriorly, segments thirty-eight; dorsally of a
brownish hue—in various transverse belts posteriorly. Scales, fifteen pairs, ovoid or
rounded, soft, rather opaque, and with cilia of moderate length on the outer and
posterior borders, while some show minute conical spines on the surface. Dorsal
division of the foot with a prominent spine, and rather long, slightly curved tapering
bristles with well-marked spinous rows, which in profile occupy half the bristle, only a
minute portion of the tip being bare.’ The ventral division has a very prominent
spinigerous lobe, and a series of slender bristles—with long spinous regions and hair-like
tips. Dorsal cirri long, tapering, with a filiform tip, and the surface has numerous short
clavate cilia. The ventral cirrus is subulate, rather long, and with short clavate cilia.
Segmental papilla begins on the fifth foot.
