THE VOYAGE OF H.M.S. CHALLENGER. 
Each foot is furnished with two very powerful black spines, which have their tips 
attenuated and slightly curved. Superiorly are some brush-shaped bristles, the filaments 
of one edge being longer than those on the other. These bristles, however, do not seem 
to present specific differences, since in this species they exactly resemble those in the 
former. A series of simple, straight bristles occurs next, with slightly bent and attenuate 
tips, having hardly a trace of a wing. The jointed bristles (PL XIXa. fig. 10) inferiorly 
have a well-marked bifid tip to the distal region, the two divisions being more nearly 
equal than in Eunice magellanica. This, however, is not of much moment, since friction 
would account for the change. The outline of the wing also diverges from that in the 
species mentioned. 
Most of the posterior hooks (PI. XIXa. fig. 11) have the points so injured by friction 
that little more can be said than that they have a principal fang and a smaller process. 
A feature of note in the sections of this species is the large size of the dorsal 
longitudinal muscles. The neural canal lies below the well-marked central region of the 
cords, and is smaller than in Eunice magellanica. The opaque, brownish granular region 
forms a wide arch above the cords, and passes down at each side. 
This form somewhat approaches the Eunice frauenfeldi of Grube ^ from St. Paul 
(west coast of Africa). The latter has at most three divisions to the branchiae, and they 
commence on the seventh instead of the tenth segment. The form of the foot is 
apparently very similar. Unfortunately the dentition is not minutely described or 
figured, and the same may be said of the bristles.

10° 30' S., long. 142° 18' E.; surface temperature, 77°‘2; depth, 8 fathoms; sea-bottom, 
coral mud. 
Two series occur, viz., two large fragments and a number of smaller specimens. 
In the smaller specimens the tentacle is considerably longer than the antennae, and 
reaches to the eighth or ninth segment. The antennae are about a third shorter, and 
the outer processes less than the latter (PL XXXVII. fig. 18). The tentacular cirri 
extend forward rather beyond the anterior border of the buccal segment. All the fore- 
going processes are distinctly articulated, the terminal joints, indeed, being moniliform. 
The eyes lie a short distance behind the base of the outer process, and have their long 
diameter directed antero-posteriorly. 
The dental armature (PL XXXVII. figs. 20, 21) is of a light brownish colour, with 
a dark brown band at the maxillary knee. The spatula-shaped posterior process of the
