iourteen to eighteen short cleaning bristles, situated more or less irregularly, all finely pectinated
distally. On the posterior side of this joint, distally of the middle, there are two rather short,
smooth bristles of about the same length as each other, one situated somewhat distally of the
other, and near the posterior distal limit of the joint two other bristles of the same type as the
former, situated close to each other, are to be found; of these the medial one is somewhat, though
only rather slightly, more powerful than the lateral one. Of the seven bristles of the small
end joint (hg. 12) the two middle claw-like ones are only about a quarter of the length of the
second endopodite joint. Of the two anterior ones, both of which are somewhat shorter than
the two former ones, the medial one, which is the longer one, is somewhat claw-like, the lateral
one is rather weak. Of the three posterior bristles the one situated most posteriorly is very
short and weak, the two others are subequal, somewhat longer than the two anterior ones and
about as strong as the weaker of these. The two main claws have a few weak secondary teeth
posteriorly, proximally of the middle, the other bristles of the end joint are smooth. Pilosity:
There are short, stifi hairs dorso-distally on the first endopodite joint and transverse groups
of short hairs posteriorly on the second endopodite joint.
Maxilla: — Protopodite (fig. 17, d = $): The first endite has ten or eleven
(usually eleven) powerful, subequal, moderately long bristles, furnished with an abundance
of long, stifi secondary bristles placed close together: there are somewhat fewer of these secondary
bristles on the outer bristles than on the inner ones. On the three inner ones the secondary
bristles continue as far as the points of the bristles, on the others they stop a short distance
from the points. Three of the latter bristles are trifurcated distally; four or five have a single
powerful point, the latter being generally without distal secondary teeth. The second endite
has five bristles (only on one specimen were there found six bristles on the maxilla of one side).
They are all rather strong, of moderate lengths, subequal, the inner one being, however, a little
shorter than the others, and all of about the same type, with a moderate number of long, stifi
secondary bristles at the middle and rather thinly pectinated distally; there is often, however,
no pectination on the inner bristle. The third endite has also five distal bristles, rather powerful
and of moderate lengths, the outer one being slightly longer than the inner ones. The four outer
ones are furnished at the middle with a moderate number of long, stifi bristles and are finely
pectinated distallv; the inner one has short, fine hairs or is, al most naked. The bristle situated
proximally on the outside of the last-mentioned process has short and exceedingly fine hairs
or is bare and is not quite as long as the outside of this process. The dorso-distal bristle on the
coxale is about as long as the outer of the distal bristles on the third endite. On the boundary
between the basale and the first endopodite joint there are only two bristles, the bristle that is
found in most of the other species of this sub-family on the anterior side of the palp is quite
absent in this form. Of these two the one tliat is fixed close to the exopodite is somewhat
longer than the bristles of the exopodite and has sparse long secondary bristles at the middle,
distally it is almost bare. The one that is fixed on the inside of the palp is almost bare and
quite short, only about a third of the length of the former (the last-mentioned bristle seems
sometimes to be absent). Exopodite: Its three bristles are subequal, somewhat longer
than this brauch. The distal one of them has short hairs, the two others are plumous.
