No. 3567 LABIDOCERA JOLLAE GROUP—FLEMINGER 19 
anterior edge of preceding segment, surface abutting segment 17 
not flattened. Fusion segment 19-21 with well-developed denticu- 
lated ridge extending length of segment. Segment 22 with distal 
spiniform process about as long as segment 23, in dorsal view process 
somewhat appressed to front edge of segment 23. 
P3 and P4 asymmetrical, right leg with Sel of Rel and Re2 enlarged 
and extending perpendicular to axis of leg (figs. 7g, 8%); in right 
lateral view enlarged spines (Sel) of P3 and P4 projecting obliquely 
posteriad (fig. 7c); P3 with Sel of Re2 bearing large irregular lamella 
on distal border, Sel usually coated with amber colored material 
resembling resinous (cement-like) secretion occurring on females 
where spermatophore is fixed to urosome. 
Basic characteristics of P5, as in jollae and kolpos, are short left 
leg; long, robust right leg bearing large, ovate chela; left leg with 
terminal segment lacking prominent spines and processes, terminal 
segment roughly perpendicular to protopodite; ventral face hirsute; 
in general, left P5 also reminiscent of that in L. mirabilis (Fleminger, 
1957, figs, 32, 33). 
Morph A differs from morph B in details of the right Al and chela 
of right P5. 
Morph A: Right Al with denticulated ridge of segment 18 ex- 
tending proximad on an elongated process that reaches distal half 
of fusion segment 13-14 (fig. 7a). Segments of chela slender, elon- 
gated; proximal segment with perpendicular digitiform process extend- 
ing from proximal end; process bearing knob on posterior face, ridge 
on anterior face. Slender distal segment (finger) opposes proximal 
segment (thumb), and closure of chela provided by finger crossing 
digitiform process of thumb (figs. 7d-h). Proximal segment of 
chela with large proximal seta; distal segment with three setae, 
one approximately one-third distance from origin of segment, second 
at midlength, third nearer apex. 
Morph B: Segment 18 of right Al with ridge extending proximad 
to suture between seements 16 and 17 (fig. 8a). Chela ovate, compact 
(figs. 8d, e, h), proximal segment roughly semicircular in lateral view 
and bearing a flaccid lamella with distal margin broadly notched; 
angle of lamella relative to segment varying from acute to perpendicu- 
lar. Large seta originating at base of lamella resembling similarly 
positioned seta in male A and suggesting that lamella homologous 
to rigid digitiform process on proximal segment of chela in male 
A. Spinule located adjacent to distal side of lamella. Distal seg- 
ment in ventral view somewhat lanceolate, with concave palmar 
surface opposing proximal segment; apex of distal segment terminating 
in small denticle; three setae on distal segment, one located close to
