and patch of long hairs on outer corner of segment bearing terminal 
claw. Maxilliped (fig. 49) in form of stout claw. Penultimate segment 
with triangular process on inner proximal corner. Claw heavily 
sclerotized and bearing two short setae on inner margin. 
Legs 1-4 biramose, each ramus 2-segmented. All legs with con- 
spicuous patches of spinules as indicated in figures. Leg 1 (fig. 50) 
exopod first segment long and recurved, second segment small bearing 
three short spines at tip; endopod first segment with outer distal 
corner produced to form prominent claw, last segment with two 
weak setae at tip. Second leg (fig. 51) exopod first segment with inner 
and outer corners produced to form spines, last segment short, bearing 
six short spines of about equal length; endopod first segment similar 
to that of exopod, last segment with five spines. Leg 3 (fig. 52) exopod 
as in leg 2 except last segment bearing seven short spines; endopod 
first segment as in leg 2, last segment with prominent spinelike process 
on outer distal corner and one small outer and four small inner spines. 
Leg 4 (fig. 53) exopod first segment with spine on outer distal corner 
only, last segment with six small spines; endopod first segment as in 
legs 2 and 3, last segment with five spines, next to outermost larger 
than other four. Leg 5 represented by knob bearing three short 
setae on outer distal corners of genital segment. 
Ma.r.—Body form as in figure 54. Total length 4.7 mm, greatest 
width 1.6 mm measured across first free thoracic segment (measure- 
ments based on single specimen from Station 552). 
Cephalic appendages as in female. Leg 1 as in female. Leg 2 (fig. 55) 
exopod first segment with prominent spine on outer distal corner and 
small seta on inner margin, second segment with six small setae on 
terminus and inner margin; endopod first segment with prominent 
spine on outer distal corner, second segment with three short but 
somewhat recurved setae. Leg 3 (fig. 56) exopod first segment with 
outer prominent spine and small seta on inner distal corner, second 
segment with six setae, fourth from outer considerably longer than 
other five; endopod first segment with outer distal corner produced to 
form prominent spine, endopod with two terminal spines and three 
small setae on inner margin, spine on inner distal corner strong and 
somewhat recurved. Leg 4 (fig. 57) exopod first segment with promi- 
nent spine on outer distal corner, second segment with six setae, 
inner three longer than outer three; endopod first segment with outer 
corner produced to form strong spine and inner margin bearing con- 
spicuous seta, second segment with two terminal spines and two inner 
short setae, spine on inner distal corner strong and slightly recurved 
as in leg 3. Leg 5 (see fig. 58) a short free segment bearing three setae 
plus single seta near base of segment. Leg 6 (see fig. 58) on outer 
distal corner of genital segment consisting of prominent inner spine
