NO. 3661 COPEPODS—HUMES AND HO 9 
third segment 42yu, 21u, and 42y from proximal to distal, with distal- 
most spiniform and minutely barbed along one edge. Both claws 
about 135y in length. 
Labrum (fig. 39) with 2 posteroventral lobes less broadly rounded 
than in ZL. varirostratus. 
Mandible (fig. 40) resembling that of LZ. varirostratus, but with 
distinct constriction separating basal region into two parts, convex 
margin of distal part bearing spinules and projected distally as a 
short blunt process. Paragnath a small lobe bearing hairs. First 
maxilla (fig. 41) bearing a smal] subterminal element in addition to 
3 terminal ones. Second maxilla (fig. 42) and maxilliped (fig. 43) 
segmented and armed as in ZL. varirostratus, but slight differences in 
ornamentation of elements as shown in figures. 
Area between maxillipeds and first pair of legs (fig. 44) not pro- 
tuberant; a sclerotized line between bases of maxillipeds. 
Legs 1-4 (figs. 45-48) segmented as in L. varirostratus, with same 
spine and setal formula. Inner seta on coxa of leg 4 short (12) and 
naked. Inner margin of basis of leg 4 without hairs. In leg 1 spinules 
along proximal margins of outer spines of exopod longer and coarser 
than those on distal margins. Endopod of leg 4 only slightly shorter 
than exopod. First segment 564 x 35y (including terminal spinous 
processes), bearing an inner distal minutely barbed spine 43y long. 
Second segment 111 x 30u (greatest dimensions including processes), 
bearing 2 terminal barbed spines 39y (outer) and 77» (inner); a few 
minute spinules along inner margin of segment. 
Leg 5 (fig. 49) with free segment much elongated, slender, and 
slightly arcuate, 172u x 23u (width 35y at level of proximal inner 
expansion). Outer convex surface bearing pointed scales. Two ter- 
minal naked setae 1224 and 190y in length. Naked seta on body near 
free segment 55u, with a few minute spinules not far from its insertion. 
Leg 6 probably represented by the 2 setae near areas of attachment 
of each egg sac (see fig. 34). 
Color in life in transmitted light as in ZL. varirostratus. 
Matz.—Body (fig. 50) resembling that of female in general form. 
Length 0.78 mm (0.73-0.81 mm) and greatest width 0.34 mm (0.30- 
0.36 mm), based on 10 specimens. Ratio of length to width of prosome 
1 St 
Segment of leg 5 measuring 36u x 101p. Genital segment (fig. 51) 
about as long as wide, 221y x 216y. No ventral intersegmental sclerite 
between these segments. Four postgenital segments 22u x 56u, 17 x 
55u, llw x 5ly, and 24y x 56u respectively. 
Caudal ramus (fig. 51) somewhat shorter than in female, 22u x 24y 
dorsally, 23u x 24u ventrally. Innermost terminal seta with row of 
288—725—68 2
