outer lobe bas two subequal bristles of moderate lengtli and strength, sometimes furnisked with
some wreatbs of long, still secondary bristles, sometimes with dense, long, soft hairs along tbe
greater part of their lengtli, and with short hairs distally. The end joint is moderately
large and has in most cases six, sometimes seven, bristles distally. These are somewhat different
in length and all moderately long and strong; at the middle they have one or more wreaths
of long, stifE secondary bristles, distally they are finely pectinated. Variation was observed
with regard to the length and equipment of the bristles, but this was rather slight. The end
joint of the exopodite is partly furnisked with soft hairs, especially on the outside.
Sixth limb: — Protopodite: The first endite has two rather short medial
bristles and one moderately long and strong distal bristle; the medial bristles have soft hairs,
the distal bristle has two or three wreaths of long, stifE secondary bristles placed obliquely,
continuing in most cases right to the point of the bristle. The second endite has one medial
bristle and three, exceptionally four, distal bristles. The third endite has one medial bristle
and seven to nine distal bristles. The endite on the first exopodite joint has one, rarely
two, medial bristles and seven to nine distal bristles. The medial bristles on the three
last-mentioned endites are moderately long, in most cases with long, soft hairs at the middle or
sometimes with rather stiff, long secondary bristles; distally they are bare or finely pectinated.
The distal bristles on these processes are of slightly different types, subequal or differing rather
slightly in length, moderately long and strong; all or almost all of thern are furnisked at the
middle with long, stiff secondary bristles and have moderately strong pectination distally.
The length, strength and equipment of these bristles are subject to some, though only rather
slight, variation. The epipodial appendage of the protopodite is represented by
four, very rarely three or five, skort bristles with soft long hairs. The second joint of the
exopodite is about twice as broad as it is long; distally it has twenty to thirty bristles differing
somewhat in length. This joint has fine, short hairs both on the medial and on the lateral side;
hairs may also be observed on the protopodite.
Seventh limb (fig. 16): — This is of moderate length, being a little more than
half the length of the shell (in some specimens with shells about 3 mm. long this appendage
was from 1,7 to 1,9 mm. long). Cleaning bristles: Situated close together distally tkere are
from six to nine dorsal and four to five ventral bristles; proximally of these there are from nine
to thirteen dorsal and seven to twelve ventral bristles scattered irregularly. These bristles are
of moderate and of somewhat different lengths, varying somewhat both from individual to
individual and on the right and left limbs of the same individual. They are furnished with from three
to nine belis cut o ff transversally distally; the tongue of the distal beil is also cut o ff rat her
transversally; proximally to the belis there are scattered irregularly on the cleaning bristles
a moderate or rather small number of rather weak secondary spines. The end comb consists
of about seven to nine moderately iong teeth, decreasing somewhat in length the more proximally
they are situated. These teeth, some of which are reproduced in ligs. 17 and 18, are furnished
proximally with from one to three rather strong secondary teeth on each side; in addition they
are provided on both sides with thin wing-like processes, which often continue with a free point
to some distance beyond the central point, which is often well-rounded, of the tooth (fig. 17);
