NO. 3567 LABIDOCERA JOLLAE GROUP—-FLEMINGER 9 
segments articulate at medialmost extension of chela; when chela 
closed, apex of distal segment crosses proximal segment near articula- 
tion with B2 between prominant ovate swelling and lateral attenuated 
prong. Left P5 (fig. 1c) relatively short, pediform; apical segment 
hirsute on medial face, bearing two short distal spines, one lateral 
spine at midlength. 
No appreciable variation was observed in the proportions of the 
spermatophore, the flaring of the TV corners in the female, the male 
P5 and the male right Al. 
ADDITIONAL DESCRIPTION.— Right Al of adult male with partial to 
complete tagmosis of the following segments: 8-9, 10-12, 13-14, 
19-21, 24-25 (based on numbering system of Giesbrecht, 1892). A1 of 
adult female and left Al of adult male with 23 perfectly separated 
segments; segments 8-9 imperfectly fused, segments 24-25 perfectly 
fused. 
Gnathobase of Mnd (fig. 12) with apical and subapical teeth 
acuminate; median teeth 1-3 bicuspidate, each cusp pointed. Three 
large basal teeth present, basals 1 and 2 usually bifid, basal 3 simple, 
acuminate, 
Johnson (1935, pl. 4, fig. 11) noted only seven teeth on the mandibu- 
lar gnathobase of jollae; his illustration lacks one of the three basals 
found in the present study. He has suggested (personal communica- 
tion) that the third basal tooth may have been overlooked since he 
used relatively low magnifications to examine the mandible. 
Adult female with symmetrical rostrum (fig. 106), prongs robust, 
proximal portion expanded, in frontal view prongs separated by 
angular notch. Diameter of subcuticular dorsal eye lenses similar 
in both sexes, not exhibiting the strong sexual dimorphism common to 
most other species of the genus. 
Penultimate stage female: Urosome with three segments. Corners 
of TV not expanded, similar to penultimate stage male. P5 in general 
resembles that in adult but with relatively smaller processes (fig. 19). 
A1 extends to posterior end of TIT. Genital segment occasionally 
with precocious, more or less incompletely developed genital pore. 
Penultimate stage male: Urosome with four segments. Right Al 
with middle segments moderately expanded proximal to site of subse- 
quent hinge. Right P5 (fig. 1k) with B2 bearing mediodistal, knoblike 
protuberance regarded as the endopod precursor. Left B2 with smaller, 
less distinct protuberance. Right and left B1 fused, ventral margin 
with asymmetrical notch closer to left leg. Right exopod uniseg- 
mented with constriction just distal to proximalmost spinous process. 
Left exopod unisegmented, shorter, width in posterior view essentially 
constant from origin to first lateral denticle. Johnson (1935, pl. 4, 
fig. 20) shows endopods of penultimate stage male P5 separated from
