No. 3567 LABIDOCERA JOLLAE GROUP—FLEMINGER 31 
P5.—In the stage V female the P5 exopod (figs. 67, 9d) bears three 
short, lateral, spinulose processes. ‘The apex is spiniform and the left 
leg is slightly smaller than the right. The female P5 increases uni- 
formly with subsequent moults, following appearance of the ap- 
pendage in stage IV (figs. 9g, 14); lateral spinous processes on the 
exopod disappear in stage VI (fig. 65).

Labidocera diandra, stage V copepodites (measurements taken from lateral view at 62.5 X 
magnification, using undissected specimens, appendage length extending from line of 
articulation of protopodite with tergite to apex of ramus; specimens selected at random 
from sample FS). 
The stage V male P5 (fig. 727) resembles that found in jollae in the 
arrangement of spinous processes and basic proportions. It differs in 
lacking rudimentary endopodal lobes and in having a knoblike pro- 
trusion on the median side of the left ramus. 
Stage V males can be separated into two groups (morph 1 and morph 
2) based on length of P5 (figs. 9e,f). This division, into a longer and
