in 40 m, Banc de Cing Métres, Aug. 19, 1964. From Dendronephthya 
kéllikert Kikenthal: 7 99 and 12 oo from 1 colony, in 8 m, Nosy 
Ovy, Isles Radama, 13°59’S, 47°46.5’E, Sept. 30, 1964. 
FremMALe.—Body (fig. 32) a little less broadened than in Z. vari- 
rostratus. Length 0.99 mm (0.91-1.09 mm) and greatest width 0.50 
mm (0.46—-0.52 mm), based on 10 specimens. Ratio of length to width 
of prosome 1.3:1. Segment of first leg separated dorsally and laterally 
from head by a furrow. Lateral areas of segments of legs 1-4 shaped 
as in figure. 
Segment of leg 5 measuring 73y x 151y. Between this segment and 
genital segment a slight ventral intersegmental sclerite. Genital seg- 
ment (fig. 33) slightly longer than wide, 172 x 156u, in dorsal view 
constricted anteriorly and posteriorly but expanded in midregion. 
A pair of crescentic sclerotized ridges on anterior dorsal surface. 
Areas of attachment of egg sacs located dorsolaterally at level of 
expanded part of segment. Each area (fig. 34) bearing 2 naked setae 
11u and 20y in length, with a small digitiform process between them. 
Three postgenital segments 34u x Sly, 234 x 68y, and 34y x 70y, 
from anterior to posterior. 
Caudal ramus (fig. 35) only slightly longer than wide, its greatest 
dimensions being 30u x 254 when measured dorsally and 33y x 25p 
when measured ventrally. Outer lateral seta 109» and naked, pedi- 
cellate dorsal seta 22u and naked, outermost distal seta 180u and 
naked, innermost distal seta 283» with inner lateral spinules, and the 
2 long median terminal setae 4184 (outer) and 550 (inner), both 
inserted between dorsal (unornamented) and ventral (with marginal 
row of spinules) flaps, and bearing lateral spinules in their midregions. 
A delicate setule on proximal outer edge of ramus, and a few surficial 
hairs dorsally. 
Dorsal surface of prosome and urosome with minute hairs. Ratio 
of length of prosome to that of urosome 2.24:1. 
Egg sacs in most ovigerous females observed broken, as in figure 
32. One intact egg sac measuring 430 x 176y, elongated, reaching 
well beyond ends of caudal rami, and containing many small eggs, 
each about 40u in diameter. 
Rostral area (fig. 36) linguiform, rounded posteroventrally. 
First antenna (fig. 37) resembling in general form that of Z. vari- 
rostratus, with same segmentation and formula for armature, but 
longer, 480u. Lengths of segments: 36u (77u along anterior margin), 
133y, 32u, 70u, 75y, 56u, and 36u respectively. All setae naked. 
Second antenna (fig. 38) also resembling that of L. varirostratus, 
with similar segmentation and armature. Last segment 135y along 
its outer edge, 86y along its inner edge, and 31y wide. Three setae on
