NO. 3567 LABIDOCERA JOLLAE GROUP—FLEMINGER < 
larger, inflated, left ramus somewhat reduced, setation concentrated 
at distal end; setae of both rami relatively short, less than length of 
urosome, proximal portions not expanded. 
TIV and TV separated by a distinct suture. In dorsal view TV 
asymmetrical, left posterior corner larger than right, both corners 
strongly flared, maximum width between apex of left and right TV 
corners about 1.2 times larger than maximum width of preceding 
seoment (fig. 1d). 
P5 with exopod bearing two lateral denticles and one short apical 
spine; endopod small, imperfectly separated from B2 by weak 
constriction (fig. 1h). 
Spermatophore, in general, resembles that found in Labidocera 
mirabilis (Fleminger, 1957). Coupler (‘‘Koppler,’’ Heberer, 1932= 
accessory ornamentation, Fleminger, 1957) relatively large, cemented 
to ventral side of urosome; in ventral view (fig. 1f) appearing as 
large, somewhat rectangular plate obscuring the urosome. Left and 
right sides of coupler extending laterodorsad in ovate lobes that 
flank right and left sides of urosome (fig. le). Left lobe longer and 
higher than right lobe, both extending dorsad well above uppermost 
limit of genital segment (fig. 1g); occasionally, lobe tending to flare 
laterally, decreasing height relative to genital segment. Spermato- 
phore sac short, about as long as, and located ventral to, right caudal 
ramus (fig. 1g). 
Adult male: Head-hooks present. TIV and TV separate. TV 
corners symmetrical, not expanded, each side ending in a minute 
denticle; caudal rami comparatively long, equal to combined lengths 
of preceding four segments (fig. 1b); rostrum asymmetrical, right 
prong reduced, left prong as in female (figs. 1/7, 10). 
Hinged right Al (fig. 1a), in dorsal view, with segment 17 expanded 
anteriad in an arched ridge lightly sculptured with irregular ribbing; 
ridge lacking denticles. Segment 17 wider (anterior-posterior limits) 
than long (proximal-distal limits), mean of ratio W/L=1.190, range 
1.0-1.5 (22 specimens selected at random). Segment 18 with two 
parallel rows of slender, closely spaced denticles; fusion segment 19-21 
with single row of blunter, shorter denticles, row extending three- 
quarters length of segment; fusion segment 19-21 roughly twice length 
of segment 18. 
Pi with unusual asymmetry in external spines on exopod of right 
leg; Sel of Rel, Re2, and Re3 elongate, distal portion swollen; same 
spines on exopod of left lez normal (fig. Im). 
Right P5 (fig. 1c) with large chela; both segments comprising chela 
elongate, slender, crescent shaped and lacking pronounced lamelliform 
ridges; straight line distance between origin and apex of distal segment 
about equal to length of right protopodite; proximal and distal
