coxal plate. Basal width of basipodite less than 
width of distal margin of coxopodite, so medial 
seta of coxopodite inserted on free portion of 
margin. Coxopodite seta very long, extending 
rather more medially than distally, its length 
slightly greater than width of intercoxal plate. 
Basipodite with row of cilia on curving medial 
margin. Armature of trimerous exopodite: first 
segment, 1 lateral spine; second segment, 1 
lateral spine, 1 medial seta; third segment, 3 
lateral spines, 1 terminal spine, 1 terminal seta, 
3 medial setae. First segment with fine spinules 
on lateral margin and row of cilia on medial 
margin. Proximal 5 spines of ramus each out- 
lined with serrate hyaline flange. Apical spine 
with external hyaline flange and entire inner 
margin. Endopodite flexed medially and prox- 
imally. Armature: first segment, 1 medial seta; 
second segment, 1 medial seta; third segment, 
1 lateral spine, set in distinct emargination, 2 
apical setae, 3 medial setae. Each of 2 basal seg- 
ments produced at distal lateral corner as spinous 
cuticular process. Spine of terminal segment 
subtended by such process, and with outlining 
hyaline flange. Every segment with row of cilia 
on lateral margin. Setae of coxopodite and rami 
with plumose ciliation. 
Second legs (Fig. 8) with well-developed 
bimerous protopodites yoked by substantial in- 
tercoxal plate. Medial seta of coxopodite on 
medial free portion of border of segment. Seta 
about as long as width of intercoxal plate. Basip- 
odite with tiny lateral seta; medial margin with 
dense row of cilia. Exopodite trimerous. Arma- 
ture: first segment, 1 lateral spine; second seg- 
ment, 1 lateral spine, 1 medial seta; third seg- 
ment, 3 lateral spines, 1 terminal spine, 1 termi- 
nal seta, 4 medial setae. First segment with row 
of fine spinules on lateral margin, cilia on 
medial margin. Proximal 5 spines of ramus each 
outlined with serrate, hyaline flange. Apical 
spine with external hyaline flange and very 
small internal flange. Endopodite flexed medi- 
ally and proximally. Armature: first segment, 
1 medial seta; second segment, 2 medial setae; 
third segment, 2 lateral spines, set in steplike 
emarginations, 1 terminal spine, 3 medial setae. 
Each of 2 basal segments produced at distal 
lateral corner as spinous cuticular process. Spines 
of terminal segment subtended by such proc- 
esses, but these somewhat less developed than 
those of basal segments. Spines of terminal seg- 
ment with hyaline flanges. Each segment with 
row of cilia on lateral margin. Setae of coxopo- 
dite and rami with plumose ciliation. 
Third legs (Fig. 9) with well-developed bi- 
merous protopodites yoked by substantial inter- 
coxal plate. Medial seta of coxopodite, about 
equal to width of intercoxal plate, inserted on 
medial free portion of distal border of segment. 
Basipodite with small lateral seta; medial margin 
with row of cilia. Exopodite, extended almost 
directly, without notable flexure, trimerous. 
Armature: first segment, 1 lateral spine; second 
segment, 1 lateral spine, 1 medial seta; third 
segment, 3 lateral spines, 1 terminal spine, 1 
terminal seta, 4 medial setae. First segment with 
row of fine spinules on lateral margin, dense 
row of cilia on medial margin. Proximal 3 spines 
of ramus each outlined with serrate, hyaline 
flange. Apical spine with external hyaline flange 
and internal margin entire. Trimerous endop- 
odite flexed medially and proximally. Armature: 
first segment, 1 medial seta; second segment, 2 
medial setae; third segment, 2 lateral spines, set 
in steplike emarginations, 2 terminal spines, 2 
medial setae. Each of 2 basal segments produced 
at distal lateral corners as small spinous cutic- 
ular processes. Spines of terminal segment sub- 
tended by such processes, but these even less 
developed than those of basal segments. Each 
segment with dense row of cilia on lateral mar- 
gin. Spines of terminal segment with hyaline 
flanges. Setae of coxopodite and rami with plu- 
mose ciliation. 
Fourth legs (Fig. 10) with well-developed 
bimerous protopodites yoked by substantial in- 
tercoxal plate. Medial seta of coxopodite in- 
serted on medial free portion of distal border 
of segment; length about equalling width of 
intercoxal plate. Medial margin of basipodite 
with short row of cilia. Exopodite, extended with 
slight flexure, trimerous. Armature: first seg- 
ment, 1 lateral spine; second segment, 1 lateral 
spine, 1 medial seta; third segment, 3 lateral 
spines, 1 terminal spine, 1 terminal seta, 4 
medial setae. First segment with row of fine 
spinules on lateral margin, cilia on medial mar- 
gin. Proximal 5 spines of ramus each outlined 
with serrate, hyaline flange. Apical spine with
