NO. 3661 COPEPODS—HUMES AND HO Pal | 
Egg sac (fig. 97) approximately 380u x 200, reaching to insertion 
of caudal ramus, containing 8-11 eggs, each about 100 in diameter. 
Rostral area broadly rounded posteroventrally. 
First antenna (433, long) similar to that of Z. spinulifer Humes 
and Frost, 1964, except that all setae are naked; segments 29y (68 
along anterior edge), 125y, 3lu, 64u, 684, 46u, and 31yp respectively. 
Second antenna (fig. 100) with 4 segments having same formula 
for armature as in previous species. Three elements on third segment 
consisting of 2 naked setae 494 and 40u and a spiniform seta 35y 
barbed along one edge. Last segment 109 along outer margin, 
73py along inner margin, and 30u wide. Two terminal claws elongated, 
slender, and nearly equal, 140y and 1338p. 
Labrum (fig. 101) with 2 posteroventral lobes. Mandible (fig. 102) 
similar to that of LZ. spinulifer, but with a pointed prominence on 
its convex margin distal to proximal spinules. Paragnath and first 
maxilla as in L. spinulifer. Second maxilla (fig. 103) similar to LZ. 
spinulifer, but with first segment broadened so that convex margin 
of appendage is angular; long spinules on proximal edge of distalmost 
seta on second segment; small setule on proximal outer area of second 
segment (as in L. spinulifer). Maxilliped (fig. 104) resembling that 
of L. spinulifer, but differing in fine ornamentation; small seta on 
third segment (as in L. spinulzfer). 
Area between maxillipeds and first pair of legs as in L. spinulvfer, 
with a sclerotized line between bases of maxillipeds as in that species. 
Legs 1-4 segmented as in 5 previous species, with same spine and 
setal formula, and closely resembling those of ZL. spinulifer. Endopod 
of leg 4 (fig. 105) only slightly shorter than exopod, its first segment 
55u x 42yu (including terminal spinous processes) with an inner distal 
plumose seta 104u long, second segment 125u x 35yu (greatest dimen- 
sions including processes), outer terminal spine 25y and finely barbed, 
inner 78 with a finely serrated fringe. Outer margin of second seg- 
ment with row of spinules (lacking distinct articulations) and inner 
margin smooth, as in L. spinulifer. 
Leg 5 (fig. 106) similar to that of Z. spinulifer, elongated free 
segment having a small proximal inner expansion. Length of segment 
151y, width at expansion 49, width near tip 16y. Outer surface 
with scalelike spines. Two terminal naked setae 394 and 88y. Seta 
on body near insertion of segment 45u and naked. 
Leg 6 probably represented by the 2 setae near areas of attachment 
of egg sac. 
Color in life in transmitted light opaque, eye red, ovary gray, egg 
sacs reddish gray. 
MatzE.—Body (fig. 107) resembling in general form that of female. 
Length 1.01 mm (0.96-1.07 mm) and greatest width 0.36 mm (0.35— 
288-725—68——4
