NO. 2661 COPEPODS—HUMES AND HO 15 
Caudal ramus (fig. 73) shorter than wide, its greatest dimensions 
being 20u x 284 when measured dorsally, 214 x 284 when measured 
ventrally. Outer lateral seta 834 long and naked, pedicellate dorsal 
seta 254 and naked, outermost distal seta 1174 with proximal inner 
spinules, innermost distal seta 2084 with spinules along both sides, 
and the 2 long median terminal setae 440 (outer) and 590 (inner), 
both inserted between dorsal (unornamented) and ventral (with 
marginal row of spinules) flaps, and both with lateral spinules in 
midregion (these spinules not as strong as in L. gentilis, and more 
like those of L. exilipes). 
Ratio of length of prosome to that of urosome 2.9:1. 
Egg sac (fig. 70) 550 x 209u, elongated, reaching far beyond ends 
of caudal rami, containing many eggs, each about 45y in diameter. 
Rostral area and first antenna (428y long) similar to those of 
L. exilipes and L. gentilis. Second antenna (fig. 74) resembling that 
of L. gentilis, but differing in details. Three naked elements on third 
segment 35y, 21y, and 20u in length from proximal to distal. Last 
segment 94u along outer margin, 60y along inner margin, and 25y 
wide. Two terminal claws unequal, not as long as in L. gentilis, one 
92u along its axis and slender, the other 77u and stouter. 
Labrum as in L. exilipes and L. gentilis. Mandible (fig. 75) similar 
to that in L. gentilis, but showing an even more pronounced con- 
striction of basal region. Paragnath and first maxilla as in L. ezilipes 
and L. gentilis. Second maxilla (fig. 76) resembling L. erilipes and 
L. gentilis, but spinulation of lash and distal seta slightly different. 
Maxilliped as in L. exilipes and L. gentilis. 
Area between maxillipeds and first pair of legs not protuberant, 
with a sclerotized line between bases of maxillipeds. 
Legs 1-4 segmented as in 3 previous species, with same spine and 
setal formula. Leg 1 similar to that of ZL. exilipes and L. gentilis. 
Legs 2 and 3 like those of L. exilipes. Leg 4 (fig. 77) resembling that 
of L. gentilis. Endopod shorter than exopod. First segment 42y x 32u 
(including terminal spinous processes), with inner distal minutely 
barbed spine 31y long. Second segment 90u x 29u (greatest dimensions 
including processes), outer terminal spine 34u with finely barbed 
fringe, inner 72 with more coarsely spinulose fringe. Proximal inner 
margin of this segment with row of very short spinules. 
Leg 5 (fig. 78) with elongated free segment having prominent inner 
basal expansion. Greatest length 148u, width 42» at expansion, 23y 
immediately distal to expansion, and 16» near tip. Outer surface 
with narrow scalelike spines. Two terminal naked setae 72y and 110u 
(the latter with a narrow membrane in its midregion). Seta on body 
near insertion of free segment about 50y long and slightly plumose; 
a few small spinules near this seta.
