NO. 3567 LABIDOCERA JOLLAE GROUP—FLEMINGER 15 
separated segments, segments 8-9 imperfectly fused, segments 24-25 
perfectly fused; right Al of adult male with partial to complete fusion 
of the following segments: 8-9, 10-12, 13-14, 19-21, 24-25. 
Exopod of P5 in adult female occasionally with extra lateral spinous 
prong as in figure 3). 
Right P1 of adult male with Se2 of Re3 not swollen, Sel of Rel-3 
swollen as in jollae. 
Penultimate stage male with right leg of P5 (fig. 3m) bearing 2-3 
minute, lateral denticles and one terminal prong. P5 of penultimate 
stage female resembles that of adult except for proportional relation- 
ships of segments (fig. 3/).

Ficure 4.—Comparisons of selected structures in 
Labidocera jollaeO and L. kolpos @: a-c, length 
of adult male right Al segments 17-21 plotted 
against length of prosome; d, maximum width of 
TV plotted against length of prosome in adult 
female. (Specimens chosen at random from 
selected localities.)

Cotoration.— Preserved specimens (5 percent formaldehyde solu- 
tion in sea water) exhibit two sets of carmine-colored structures, one 
between TI and TII, the other in TIII, as described above for jollae. 
The swimming legs also show a faint tint of blue in the cuticle. 
Living specimens were found to be uniformly blue-green as in ollae. 
Examination for chromatophores was carried out only on preserved 
material. The results suggest a chromatophore array similar to that 
in jollae but, due to fading of pigments, this should be confirmed by 
examination of living material. 
Typrs.—Female holotype, USNM 110747, allotype, USNM 
110748, selected from material collected at station II-1 (lat. 28°03’ N, 
long. 111°16.5’ W), located a few yards offshore of a steeply sloped 
sand beach in a small cove, roughly 20 miles north of Guaymas,
