second protopodite joint and the second endopodite joint there are groups of short, fine hairs,
and dorso-distally on the first endopodite joint there are also a few short hairs.
Maxilla: — Protopodite (fig. 11): The first endite is furnished with seven
powerful bristles of moderate length. Of these the two inner ones are subequal and furnished
with a few oblique wreaths of long, stifï secondary bristles ; the distal one of these wreaths continues
right to the point of the bristles. The other five are subequal and somewhat shorter than the
two inner ones; of these five the two outer ones are furnished with rather numerous long, stifï
secondary bristles and are trifureated distally; the other three, one of which is very powerful,
are furnished with rather few long, stifï secondary bristles, distally of which there are some
short secondary teeth, and have a simple point. The second endite has five rather strong
subequal bristles. Of these the inner one has short and exceedingly fine hairs or is bare, one
is only rather weakly pectinated distally and the three others have at the middle a few long stifï,
secondary bristles and are pectinated distally; on the one next to the outer one the pectination
is rather strong, on the two others it is rather weak. The third endite has also five rather powerful
distal bristles, all of about the same length except the inner one, which is rather short and weak.
The last-mentioned bristle has short and exceedingly fine hairs or is bare; of the other four,
ail of which have a few stifï, secondary bristles at the middle, the inner one is bare distally,
the others are rather weakly or very weakly pectinated distally. The dorso-distal bristle on
the coxale is about as long as the outer bristle on the third endite. Of the two bristles on the
boundary between the basale and the first endopodite joint the one that is situated near the
exopodite is about a third of the length of the bristles of the exopodite, the other is still shorter;
both are bare. Of the three bristles of the exopodite the distal one is bare, the two others
are plumous; all of them are of about the same length as this branch. Endopodite: First joint
(fig. 12): Distally on the anterior edge there is a single rather long, plumous bristle. Distally
on the posterior edge there are two bristles, one of which is long and powerful, furnished at the
middle with rather weak secondary teeth and characterized especially by being bent at almost
a right angle somewhat distally of half its length, the other is considerablv shorter and weaker
and has short, fine hairs. Proximally of these two bristles the edge of the joint is characterized
by a strongly projecting, distally bifurcated verruca. The end joint is rather strongly chitinized
and lias only eleven bristles: three bare a-bristles of moderate length and strength; three
b-bristles, of which the anterior one is moderately long, rather strong, furnished at the middle
with a few weak secondary teeth and plumous distally, the two others are naked, weak and short,
their lengths being somewhat unlike, the shorter one not quite half as long as the anterior one;
two c-bristles of the same type and sizes as the short b-bristles, the anterior one being the shorter,
and three d-bristles, subequal, very powerful, especially the two anterior ones, the posterior
one rather strongly pectinated, the two anterior ones furnished at the middle with rather few
fairly strong secondary teeth. Pilosity: The first endopodite joint has transverse series of
short, fine hairs.
F i f t h 1 i m b: — Protopodit e: The first endite (fig. lô, £ — $) is furnished
with only five bristles. Of these bristles no. 1, counting from the anterior side of the limb,
is very small, furnished in most cases with long, stifï secondary bristles. The others are of mode-
