shorter than the distal ones; the shorter ones among the former are only about half as long as
this joint, the longest among the latter being almost as long as the total length of the first and
second endopodite joints. The proximal ones have short hairs or are almost bare, the distal
ones have moderately long, stiff secondary bristles. The mime ro us medial cleaning bristles
are moderately long, subequal, finely pectinated or almost bare, arranged in about eleven or
twelve transversal rows. Postero-distally on this joint there are eight bristles, two of which
are situated somewhat distally of the other six; they differ somewhat in length, the longest
are somewhat longer than the first endopodite joint; they all have short hairs. (Are the two
distal ones of these bristles homologous with the two distal ones in the genus Astero’pe’i) The
end joint has five bristles. Three of these are subequal and comparatively powerful and long,
about as long as the total length of the first and second endopodite joints, almost bare, with
only sparse short hairs. One, situated between the two anterior of three former ones, is
only sliglitly shorter than these, but considerably weaker; it lias short hairs. The remaining
one, situated behind the others, is of the saine type as the last-mentioned one, but somewhat
shorter. Pilosity: Basale: On the medial side there are rather abundant groups of moderately
long, sti ff hairs.
Maxilla (fig. 10): — Protopodite: Basale: Dorso-distally, a short distance
from the boundary of the endopodite, this joint has a group of three long, powerful, bare bristles
differing somewhat in length; the longest is almost twice as long as the endopodite. Proximally,
close to these bristles, there is a very short and weak bristle and a short distance proximally
of this another similar one. Distally of the three long bristles and on the inside of the joint,
along the boundary of the endopodite, there is a series of eight more or less short, weak bristles.
Ventero-distally there is a group of three relatively weak bristles on this joint, one of which
is about as long as the height of this joint, the two others about half as long (= exopodite?).
Endopodite: First joint: Along the anterior side there is a series of four short bristles;
the distal one is longest, the others shorter the more proximally they are placed. These bristles,
like the short bristles of the basale, are bare or furnished with exceedingly fine, short hairs
and end distally in a short, fine hair. Postero-distally this joint has a single bristle, which is
about as long as the endopodite. The end joint lias six rather long bristles differing somewhat
in length ; the longest is about the same length as the postero-distal bristle of the first endopodite
joint. These bristles, like the postero-distal bristle of the first endopodite joint, hâve short
hairs. Pilosity: The basale and the first endopodite joint are furnished on the inside with
abundant groups of moderately long, stiff hairs.
Fifth limb: — Comb (fig. Il): The dorsal edge forms, somewhat in front of the middle,
a process that points somewhat forward and is rounded distally. On this process and
along the proximal half of the dorsal edge of the comb there is a series of short,
finely annulated bristles ending distally in a short, fine hair; seven of these bristles were observed
on the right fifth limb, nine on the left. Of the bristles along the ventral edge of the comb those
that are situated near the anterior point of the comb are on an average somewhat shorter than
the rest. The.remains of the distal exopodite joints are not distinctly defined as a verruca.
They have two rather long, subequal bristles, the points of which do not reach the distal
