cephalothorax-abdomen ratios, based on four 
of these, are: allotype 1.90 mm., 2.91:1; para- 
types 1.92 mm., 2.9:1; 1.94 mm., 2.7:1; 2.00 
mm., 2.7 : 1. 
DESCRIPTION : The general shape of the adult 
female is similar to other species of the genus 
Candacia. The head is truncate in dorsal view; 
thoracic segments 4 and 5 are fused and pro- 
duced posteriorly into two symmetrical points 
(Fig. 22). In lateral view (Fig. 23), a small 
hump is visible on the dorsal surface at the 
junction of the head and first thoracic segment. 
The genital segment is slightly asymmetrical; 
the lateral swelling on the left side is smaller 
and somewhat more expanded than that on the 
right side (Figs. 24, 25). A single dorsal spine 
is present on each swelling. The abdominal seg- 
ments and furca have the following proportions 
(based on holotype): 40, 26, 19, 15 — 100. 
The first antennae, when held against the 
body, reach to about the tips of the furcal rami. 
The proximal part of the antenna is thickened 
and consists of seven segments (Fig. 26). Seg- 
ments 1 through 6 and 8 through 12 have one 
spine. There are indications that additional seg- 
ments are furnished with a spine but no perfect 
antennae were present among the specimens 
examined. 
The second antennae are similar to those of 
other species of Candacia. Basipodal segments 1 
and 2 have one seta. Segment 2 of the endopod 
ends in two lobes. The outer lobe has six large 
and one small setae. The inner lobe has five 
large and one small setae and one minute seta 
proximad of the small one. 
The exopod of the mandible apparently con- 
sists of four segments, the first three of which 
are furnished with a single seta. The terminal 
segment has two setae. The endopod is com- 
posed of one segment which is provided with 
six setae. The basal tooth of the mandible is 
furnished with two subequal points and a mar- 
ginal point (Fig. 27). 
The first maxillae are best described by ref- 
erence to Figure 28. 
The second maxillae are of large size (Fig. 
29). The basal segment has four lobes. There 
are three long and one very short setae on the 
first lobe, one long and one short seta on the 
second lobe, one long and one short spine on the 
PACIFIC SCIENCE, Vol. XIV, July I960 
third lobe, and one long and one short spine on 
the fourth lobe. The second basipod segment has 
two subequal spines, the proximal one has a 
minute spine at its base. The endopod is fur- 
nished with three spines, the middle of which 
is slightly longest. In addition there are three 
bristles on the terminal part of the endopod. 
The maxillipeds (Fig. 30) are small. The 
first basal segment is more than twice as long 
as the second basal segment. The former has 
one seta at a point about two-thirds of the 
segment length from the proximal end and two 
setae on the distolateral corner. The second basal 
segment is furnished with three unequal setae 
and one other seta on the apparent apex. Hair 
is present on the internal margin of this seg- 
ment. The five endopodal segments are each 
furnished with one long and one short seta. The 
long seta on the terminal segment is somewhat 
longer than those on the other endopodal seg- 
ments. 
The third exopodal segments of swimming 
feet 1 to 4 are shown in Figures 31-34. The 
relative lengths of these segments to their re- 
spective terminal spines are as follows (based 
on several specimens): 1:1, 1:0.8 (estimate), 
1 :0.6, and 1:1. 
The fifth feet are symmetrical and each termi- 
nates in one long stout finger and one short 
spinous process (Fig. 35). The former is about 
three times longer than the latter. The finger 
has several rounded serrations distally, and the 
spinous process is finely serrate. The external 
margin of the segment has two spinous proc- 
esses. The internal margin bears two subequal 
setae in all observed specimens except one 
("Hugh M. Smith” cruise 47, sta. 29-1) which 
has three internal setae on one foot. 
The following appendages of the preserved 
holotype are pigmented: the distal 18 segments 
of the first antennae, the distal spinelike claw 
on the first inner lobe of the first maxillae, por- 
tions of the first basipod segment and the distal 
five spines of the second maxillae, basipodal 
segments 1 and 2 of the first four pairs of swim- 
ming feet, and the terminal finger and spinous 
process of the fifth pair of feet. The female 
collected on "Hugh M. Smith” cruise 47, sta. 
29, has additional pigmentation as follows: the 
distal 20 segments of first antennae, the spines
