one or somewhat shorter. Of the two anterior ones, both rather weak, the latéral one
is about half, the medial one about a quarter of the length of the main claw. Of the
three posterior ones, all rather weak, one is somewhat shorter than the main claw, one
about half the length of the former, and the third, as usual in this sub-family, almost
com-pletely reduced. All the bristles of the end joint are quite smooth. Pilosity: The second
protopodite joint has numerous groups of short, stiflf, fine hairs; the other joints hâve only
sparse hairs or are quite smooth.
Maxilla: — Pro topod ite: The -first endite has twelve powerful, subequal
bristles of moderate length, all furnished with a number of wreaths of long, stiff secondary
bristles. About half these bristles have distally a moderate number of secondary teeth, usuallv
rather coarse, and a simple and powerful point; the remainder, in most cases somewhat weaker
than the former ones, are strongly pectinated distally right out to the points, so that they appear
more or less strikingly three-pointed distally. In a few cases thirteen bristles were observed on
this process. The second endite (hg. 11) has seven distal bristles, all rather powerful, of moderate
length, subequal except for the fifth and sixth, reckoning from outside, which are most frequenti}’
somewhat shorter than the rest. They all have a somewhat varying number of wreaths of long,
stiff secondary bristles; distally of these secondary bristles bristle no. 5 has only a few secondary
teeth, no. 6 is rather finely pectinated distally and the rest are more or less coarsely pectinated
distally. The third endite (fig. 12) has nine or ten distal bristles, all fumåakt*! with a more
or less large number of irregulär wreaths of long, stiff secondary bristles. Three to four of the
most distally situated of these bristles are considerably shorter than the rest and are usually
furnished distally with only a few secondary teeth; Vue others are of moderate length, subequal
— the outer one being, however, somewhat longer than the rest — and distallv they are either
rather finely pectinated like the two outer ones and the innermost one or else coarsely pectinated.
The proximal bristle on this endite is sparsely furnished with short hairs and is about as long
as the outside of this process. The bristle situated distallv of the epipodial appendage is about
as long as the first endopodite joint. Of the three bristles on the boundary between the basale
and the first endopodite joint the one situated near the exopodite is of about the same length
and type as the twc< distal bristles on the exopodite, the two others are short, about half as long
as the first endopodite joint or somewhat shorter, and have short hairs or are quite naked. In
one case two bvistles were observed instead of one on the anterior edge of the endopodite.
Exopodite;: The two distal bristles are usually subequal and somewhat longer than the
exopodite; th« remaining bristle is about half the length of the former ones; they all have long,
stiff seconda ry bristles and distally they have short hairs. On one of the „A n t a r c t i c“
specimens ( the other specimen brought home by this expedition was defective with regard
to this char.acter) one of the two distal bristles had short hairs. E ndopodite: First joint:
Distally (fqg- 10) this has four (in one case on one maxilla there were only three, in nnother case
five) anterior and four posterior bristles. The former are moderately long and strong, in most
cases dimifuishing somewhat in length according as they are situated more posteriorlv; all are
sparselv f urnished with short hairs. The four posterior ones decrease rather rapidly in length
and strength according as they are situated more anteriorly; they are all sparsely but coarsely
