The posterior foot-jaws are small but moderately robust ; 
a stout seta springs from the inner distal angle of the first 
joint, while the end joint bears a moderately stout terminal 
claw (fig. 5). 
In the first pair of thoracic feet (fig. 6) the second and 
third joints of the outer branches are together about equal in 
length to the first joint ; the inner branches are uniarticulate 
and more or less rudimentary. ‘The second, third, and fourth — 
pairs are somewhat similar to each other in structure; the 
outer branches, which are all three-jointed, are long and 
slender, the first and third joints are elongated and subequal, 
but the middle joint is short ; the inner branches are nearly 
obsolete, being each composed of a single minute joint bearing 
two small terminal sete, as shown by figure 7, which repre- 
sents the fourth pair. In the fifth pair the secondary branches 
are elongated and very slender, and provided with three ter- 
minal setee of unequal length, the innermost being the smallest, 
a small seta also springs from near the middle of the outer 
margin, as shown in the drawing ; the basal joint, which forms 
a narrow border along the edge of the thoracic segment, bears 
a small seta near its inner extremity, while it terminates 
exteriorly in forming the base of a long slender seta (fig. 8). 
Habitat.—Lat. 76° 17' N., long. 21° 36’ K., 60 fathoms; 
rare. Only a single specimen of this very distinct form was 
observed. It combines in some measure the general charac- 
ters of Cletodes monensis, 1. C. Thompson, and C. longicau- 
data, Brady & Robertson, having the dorsal hooks of the one 
and the long caudal furca of the other. 
Nannopus palustris, Brady. 
One or two specimens of this species occurred in a gathering 
from the east side of Kolguev Island collected on June 12th ; 
this is a littoral as well as a brackish-water species. 
Platychelipus littoralis, Brady. 
This species, which bears a general resemblance to Nan- 
nopus and is frequently found in the British seas associated 
with that form, was obtained sparingly in the same gathering 
with it from the east side of Kolguev Island. 
Dactylopus tenuiremis, Brady & Robertson. 
The gathering in which this species was observed was col- 
lected on the 13th of July to the east of Hope Island at a 
depth of 100 to 110 fathoms ; the species appeared to be very 
rare.
