Along the distal half of the anterior edge of the second joint there is a series of seven moderately
long bristles of somewhafc different lengths, the proximal one rather short, ail furnished ventralh’
with rather long, stifï secondary bristles arranged in two rows and vvith short hairs distally.
Laterally this joint has three rather short, short-haired bristles near the distal boundary. Third
joint: Along the anterior edge there are twelve bristles, five of which are attached along the
boundary of the fourth joint. Of the five distal of these bristles the one situated most medially
is relatively short, only about as long as the anterior edge of the fourth joint; the one situated
most laterally is very long, about as long as or somewhat longer than the total length of the four
(definitive) distal joints; the other three are rather considerably shorter than the last-mentioned
one and decrease somewhat in length the more medially they are situated. The bristles situated
proximally of these five are of moderate and somewhat different lengths. The two medial of the
five distal of these bristles are furnished with comparatively short hairs, ail the others are provided
with a larger or smaller number of.more or less powerful secondary bristles, in most cases arranged
in two rows on the ventral side of the bristles; these bristles have most frequently fine, short
hairs distally. Posteriorly this joint has a single moderately long bristle with short, fine hairs.
Fourth joint: This has a single bristle antero-distally which is somewhat shorter than the total
length of the two (definitive) distal joints and is provided with long, soft secondary bristles arranged
on all sides, and is furnished with short hairs distally. Posteriorly this joint has five bristles
distally, which increase somewhat in length the more laterally they are placed; the medial
one is relatively short, not quite so long as the back edge of this joint, the lateral one is somewhat
longer than the total length of the four (definitive) distal joints. The medial one of these bristles
has short hairs, the others are rather abundantly supplied with soft, rather long secondary
bristles along the greater part of their length. Sensory bristle of the fifth joint: This has a very
powerfully developed stem, which is about as long as the posterior edge of the third to the sixth
(definitive) joints. Distally it is rounded and has there about fifteen (the number was not quite
certain, as the specimen was defective) sensorial filaments of about the same type; these are about
half the length of the stem and are rounded distally and there provided with a short, fine
sensorial hair. The accessory sensorial filaments are exceedingly numerous, somewhat narrower
than the distal ones but of about the same length as these, and are arranged in about
sixty more or less distinct transverse^rows. The bristle of the original sixth joint is about
as long as the posterior edge of the sixth definitive joint, with long, soft secondary bristles;
it has short hairs distally. Original seventh and eighth joints: The a-claw is about as long
as or somewhat shorter than the anterior side of the fifth and sixth (definitive) joints, is relatively
narrow, and of almost uniform thickness along the greater part of its length, straight, directed
ventrally and pointed distally; it is bare and only slightly annulated. The b-bristle is rather
long, but considerably shorter than the c- and f-bristles (broken on both antennae); it has very
numerous sensorial filaments. The c- and f-filaments are subequal, somewhat longer than the
length of the shell, the lengths measured being 6,8—7 mm.; they have numerous sensorial
filaments, 48—49 being observed on the c-bristle, 55—56 on the f-bristle. The d- and e-bristles
issue, as in the males of Asterope, on a verruciform protubérance (cf. fig. 8 of A. norvégien),
penetrate between the c- and g-bristles and are held medially; they are not quite as long as
