peg. Basale: This has seven ventral bristles, viz: two a-bristles, one b-bristle, two c-bristles
and two d-bristles. Ofthese the a-bristles, the longer of the c-bristles and the d-bristles are of
about the same proportions as are shown in pi. XYI, fig. 2, G. S. Brady, 1897. The b-bristle and
the shorter of the two c-bristles, which are not drawn in this figure of Buady’s, are short, the
former being about the same length as the a-bristles and distinguished by being displaced to rather
a great extent dorsally ; the short c-bristle is almost entirelv reduced. The three bristles on the dorsal
side of this joint are about as long as these bristles on the above-mentioned figure of G. S. Brady’s,
i. e. the proximal one, situated somewhat in front of the middle of the joint, generally does not
reach with its point the distal boundary of the joint, the two distal bristles are subequal and
slightly longer than the proximal one; all three have short hairs or are almost bare.
Exo-p o d i t e: This is somewhat longer than the dorsal side of the first endopodite joint. Its two
bristles are relatively short, the proximal one of about the length of this branch, the distal one
about half this length; both have short hairs. E n d o p o d i t e (fig. H): Ail the four bristles
of the first joint have short hairs. The second joint has on its anterior side a sparse series of
fi ve moderately long bristles with short and sparse hairs; these bristles differ somewhat in length.
In addition this joint hashcre a rather large number (about 28—35) ofrather short cleaningbristles,
arranged in several more or less irregulär rows running obliquelv upwards and forwards or else
almost entirely without any regulär arrangement. Most of the cleaning bristles have extremelv
fine and double pectination (of the type shown in fig. 8 of M. (Cypridinudes) acuminata in this
treatise; drawn smooth in the adjoining figure); the rest are coarsely pectinated. Posteriorly
this joint has four subequal bristles with short, coarse hairs, two next to eaeh other distally,
and two, one of them a little proximally of the other, a short distance proximallv of the two
former ones; the two distal ones are equal in strength. The end joint has seven bristles. Of
these the medial-anterior one is rather powerful, claw-shaped, and rather long, generally about
half the length of the second endopodite joint. The one situated most posteriorly is very weak
and short, as is usually the case in this group of forms; the five remaining ones are subequal,
rather weak and short; in most cases about half as long as the main claw. The main claw is
bare, the remaining six bristles are more or less pectinated. Pilositv: The first endopodite
joint has short hairs dorso-distally, the second endopodite joint has transverse rows of short,
stifï hairs along the posterior side.
Maxilla: — Protopodite: The first endite (fig. 15) has in most cases twelve
powerful bristles of moderate length. Of these the two inner ones are subequal, rather
consid-erably longer than the others and furnished with two or three wreaths of rather short, sti tf
secondary bristles; distally of these they are rather strongly pectinated. The ten outer ones
are often subequal; their lengths vary, however, to some extent; most of them have at the
middle wreaths of long, stifï secondary bristles, more copious on the inner ones than on the
outer, and distally of these more or less powerful secondary teetli. In a rather large number
of specimens there was a slight variation from the type shown in the figure to be observed.
Outside the outer bristle of those drawn in the figure an additional bristle may often be found;
this thirteenth one is quite short and weakly pectinated. The second endite (fig. 16) has five
rather powerful bristles of moderate length, the three outer ones usually somewhat longer than
