Protopodite: First endite: The distal bristles are of moderate length and strength,
subequal, furnished witli a number of wreaths of long, stiff secondary bristles extending right
to the points of the bristles; the medial bristles are short and have long hairs. Second endite:
This has one distal bristle rather considerablv shorter than others, but rather strong, with long
secondary bristles in the middle, and with short hairs or almost bare distally; the other distal
bristles are of moderate length and strength and subequal; they all have several wreaths of long,
stiff secondary bristles and are pectinated or almost smooth distally. The medial bristles are
short and have long hairs. Third endite : One of the distal bristles is somewhat shorter than the
others, very powerful, and has a few wreaths of long, stiff secondary bristles in the middle and
a few very powerful secondary teeth distallv. The other distal bristles are of moderate length
and strength and subequal; one of the dorsal ones is, however, in most cases somewhat shorter
and weaker than the others; either all of them have long, stiff secondary bristles in the middle
or one or more may be without them; they are pectinated or bare distally. The medial bristles
are of about the same length as the distal ones or somewhat shorter; they have a few wreaths
of long, stiff secondary bristles and are pectinated or bare distally. The bristles of the e p
i-podial appendage are short, with short hairs or bare ; in only one case was one of these
bristles found to have long and soft hairs. Exopodite: Endite of the first joint: The
distal and medial bristles are of about the same length and type as the bristles on the third
endite of the protopodite; one (in one case two were observed) is somewhat shorter than most
of the others, but it is very powerful, it has some wreaths of long, stiff secondary bristles in the
middle and is furnished distally with a few powerful secondary teeth; two, situated laterally,
one ventrally, the other at about half the height of the endite, were considerably shorter and
weaker than the rest and had short hairs; in one case only one of them, the ventral one, was
found on the limb of the one side, the other was missing. The bristles of the second exopodite
joint are all situated near the ventral edge and there is no pronounced gap between the posterior
