The cephalie plate is comparatively adherent;,for the dorsal collar is restricted, and
tll0 edge externally bends over into that of the supraoral fold, the whole plate being
more limited than usual. A s#H>ral fold occurs within, and externally is the lower
lip on the ventral border; the dorso-lateral continuation of the lip bears the first group
of branohise. The tentacles have the normal structure and a deep groove. The segment
following the foregoing has no.distinct shield, the anterior edge ventrally forming a free
border and ending laterally on each side in a rounded free flap. A second free anterior
rimJBllows, also ending laterally in a rounded flap opposite the second branchia.
In the middle line is a large shield which sometimes indents the segment behind it,:
Opposite the third branchia and the first bristle-tuft is a third rounded external flap,
Which passes further dörsalward than the other two. It abuts on a narrower shield
than Tthhee obnrea ninch firgoen ta. re three in number, arising from the second, third and fourth
segments, and each forms a series of long, simple filaments which are attached to
a single basal process. The tufts on each side are separated transversely by a
consiTdehrea bbleid ys piasc ee. nlarged anteriorly, and gradually tapers posteriorly to the termi.nal
anus. Dorsally it is rounded; ventrally are about ten to twelve shields anteriorly, and
then a median groove passes to the; posterior end. Seventeen pairs of vertical, flattened
setigerous processes occur anteriorly, the first being in a line with the last branohial tuft.
The bristles (Plate CXXV, fig. ||a r e dull golden and in two series, a longer and shorter;
the former are deeply inserted, have shafts nearly; qf uniform diameter , throughout,
and have comparatively short tapering tips with wingd; which are broad at the
commencement, but taper distally. The condition of the tip, however, is variable,
apparently from injury, since many are short with short and broad wings and tips,
that taper little—the result in all probability of injury. The shorter series has
winged and tapering tips; though a few at the edge present; short (broken ?) tips;
with broad wings. A minute papilla occurs on the ventral side of the setigerous process
from the second to the eighth bristled segment. ISÏörepyer, just b#ow the papilla a
little flap is developed at the dorsal end of; each hook-row, and sloping backward behind
it from the first bristled segment (which has nof hobksj to the last, whepe, however,
it is less distinct. No hooks occur apposite the first bristle-bundle; a single row js;
present on the next 'fo|tb, and for several feet thereafter, but the eighth has two rows.1
The hooks (Plate CXXV, figs. 5 andga) have in lateral view about four teeth above
1 From the eleventh to the twentieth segment the hooks are in a double4ow and semi-opposite
(Lo Bianco).
