and dactylus long, each about equal to combined lengths of ischium and merus, 
which bear inner distal teeth, 
Distal joints of first peraeopod missing, 
Second peraeopod with exopod longer than basis, which is stout and very 
little longer than rest of limb; ischinm marked off by a suture but not distinetly 
articulated ; merus (which has 4 small outer tooth near distal end) as long as pro- 
podus, and fully two-thirds as Jong as carpus; the last-named is as long as the 
dactylus, which bears slender distal setae, the longest exeeeding the joint in length. 
Third and fourth perseopods with exopods, moderately well-developed but 
as usual 4 little smaller than those of first and second legs; merus not much shorter 
than basis and twice as long as carpus and propodus together; carpus with the 
last of the distal setae stouter than the others and reaching to tip of dactylus; 
penultimate outer carpal seta, like the slender propodal seta, reaching well beyond 
level of tip of dactylus, which is about as long as propodus, and has a very short 
claw-like terminal portion distinctly separated. Fifth peraeopod a little shorter 
than fourth, with basis as usual more slender. 
Pedunele of uropod half as long again as telson, with two bristles near distal 
end of inner margin; endopod a little longer than exopod and not much shorter 
than pedunole; it is three-segmentate, the first joint somewhat shorter than rest 
of ramus, and with two short spines and one longer spine on inner margin ; second 
joint distinctly longer than third and like it with a single inner spine at distal 
eud; terminal spine of endopod half as long as the ramus and shorter than the 
longer of the two very unequal terminal spines of exopod,

Gynoplasrvils lata sp. nov. 
Ovigerous female, Carapace fully one-third of total length of animal and more 
than half ag long again as pedigerous somites together; it is half as long again as 
deep, and seen from above is subtriangular in shape, broadest at binder end, where 
it is as wide as long; back and sides with numerous longitudinal carinae; the dorgo- 
lateral ridges are restricted to posterior half, and anteriod te them on each side is 
a large, shallow depression; between the dorsal ridges there are faint eroded pits. 
Antero-lateral margin exeavated to form a large antennal notch; antero-lateral 
angle produced, acute. Pseudorostral lobes meeting in front of veular lobe for 
a distance equal to nearly one-tifth length of carapace, anteriorly gaping slighily 
fora very short distance ; each lobe is pointed in front, both ax seen from above and 
from the side, and on its dorsum has a ridge-like longitudinal fold in front of ocu- 
lar lobe; sutures fused, sa that eye lobe is not well defined. No distinct lenses, 
but.a pair of raised smooth oval areas at front of ocular lobe. 
First to third pedigerous somites successively increasing in length dorsally, 
and as wide as is carapace across hinder end; pleural parts of third and fourth con- 
siderably expanded laterally; dorsum of second and third wiih a pair of obsolete 
elevations, that of fourth with a pair of longitudinal ridges. 
Pleon six-sevenths ay long as cephalothorax; fifth somite fully half as long 
again as sixth, which is broad, half as wide again as long; telson subtriangular in 
shape as seen from above, and not much shorter than sixth somite; its sides are 
slightly rounded, and no apical spines are discernible. 
First antenna with second joint of peduncle half as long as first and two-
