First antenna: — The bristles of the third, i’ourth and sixth joints and the
a-bristle of the seventh joint have about the sanie position and the same relative lengths as in
C. (V.) norvegica, The posterior bristle of the fourth joint is somewhat shorter relativelv. All
these bristles have short hairs or are almost naked. The sensory bristle of the fifth joint is of
about the sanie lengtli as the second to the fourth joints (counting on the posterior side) or
somewhat longer. Of its thirteen sensory filaments — ail entirely without secondary spines
-the nine proximal ones are separated from the distal ones by a rather wide gap and, compared
to the latter, they are relativelv thick and long (attaining about a third to a half of the whole
length of the bristle); the three following ones are only about a fifth of the length of the bristle,
the distal one is still shorter. Of the bristles on the seventh and eighth joints the c-, f- and
g-bristles are rather long, the c-bristle attaining about the same length as the seven distal joints,
the f-bristle is somewhat longer, the g-bristle is about as long as the whole antenna. The
b-bristle is about as long as the total length of the fourth and fifth joints and has five sensory
filaments, each with one or two secondary spines. The c-bristle has ten sensory filaments each
furnished with from none to two (most of the distal ones with noue) secondary spines. The
f-bristle similarly has ten sensory filaments, each with from none to five secondary spines.
The g-bristle has eleven sensory filaments, each having similarly from none to five secondary
spines. The secondary spines on ail the distal bristles are rather strong. The simple sensory
bristles d and e are about as long as the four distal joints. Pilosity: The second joint has
anter-iorly and posteriorly a few almost invisible transverse rows of short, fine hairs; apart from
these this antenna is smooth.
Second antenna: — Protopodite: Length about 0,9 mm. The
medial-distal bristle is of moderate length, not quite so long as the longest of the four
proximal bristles of the first endopodite joint, bare or almost so (fig. 12). Exopodite:
The first joint is about as long as the total length of ail the following joints, the
second joint about as long as the total length of the two following ones, the
remaining ones are subequal. The bristle of the second joint is about as long as the
total length of the six following joints, and is furnished ventrally with numerous moderately
strong spines, arranged in two rows. The proportion between the length of the long natatory
bristles and the total length of the exopodite is about three to two. These bristles are equipped
with broad natatory hairs. The end joint has four bristles, of which the dorsal one
is about as long as the total length of the five distal joints; like the otliers, it is furnished with
long natatory hairs situated rather close together. The third to the ninth joints have
powerful, rather long and conical basal spines, perhaps even a little longer relatively than
those in C. (V.) norvegica; they decrease in strength and length the more proximallv they are
situated, the one on the third joint being of rather moderate proportions. At the base of the
bristle on the second joint there are no spines at ail. F n d o p o d i te: This is very short,
two-jointed or with a very faint indication of being three-jointed. The first joint has a group of
four bristles proximally, one of which is rather long, considerably longer than the whole
endopodite, the three otliers not half as long as this bristle; they are bare or almost so. In addition
there is presumably to be fourni a single bristle situated more distally on this joint, attaining
