Candacia — Grice and Jones

The dorsal surface of the anal segment (Fig. 
3) bears a very prominent, broad bifurcate 
process pointing caudad. The posterior lateral 
surface of each of the diverging tubercles of 
this process has a patch of very fine teeth visible 
under 100X magnification. In the holotype, 
these tubercles appear to be slightly asymme- 
trical in size and in details of minute swellings 
and creases. Examination of paratype material 
indicates that there is variation in these details 
and also in the ventral lobe of the second ab- 
dominal segment. 
The furcal rami (Fig. 3) are longer than 
wide. The outermost furcal setae are thick and 
originate high on the lateral margins of the 
rami. There is a small tooth dorsad of the origin 
of the middle major seta of each ramus. 
The proximal seven segments of the first 
antennae are thickened. The first segment has 
three small spines, and segments 2 through 6 
have small marginal spines ( Fig. 6 ) . It is prob- 
able that additional segments had spines which 
have been lost in the material at hand. 
The second antennae are similar to those of 
other members of the genus. The exopod has 
six setae plus a minute one; the second en- 
dopodal segment is divided into two lobes, the 
external with six setae plus a minute one and 
the internal with five setae plus a minute one. 
The exopod of the mandibular palpus has 
five setae; the endopod has six. The mandibular 
blades (Fig. 7) are composed of a large point 
and a basal tooth with three points decreasing 
in length mediad. 
The first maxillae are best described by ref- 
erence to Figure 8. 
The second maxillae (Fig. 9) are large and 
have the form of maxillipeds. The basal seg- 
ment is composed of four lobes. There is a single 
long seta on the first lobe with a minute seta 
at its base, two small setae on the internal mar- 
gin of the second lobe, and one large spine with 
a short spine at its base on each of the third 
and fourth lobes. There are two long spines of 
about equal length on the second basipodal seg- 
ment, and the proximal one has a minute spine 
at its base. Distad of the second basipodal seg- 
ment are three very long, curved spines, the 
middle of which is the longest. Three very 
small bristles arise from the base of the distal 
spine. 
The maxillipeds are reduced in length (Fig. 
10). The first segment is about as long as the 
remaining segments combined and is 1.7 times 
the length of the second. There is a tubercle on 
the internal margin of the first segment near 
the proximal end and a single long seta just 
distad of the midpoint of that margin. Two 
slender setae, one twice the length of the other, 
arise from the junction of the first and second 
segments. At about the midpoint of the internal 
margin of the second segment, there is a patch 
of hair proximad of three setae. The distal end 
of this segment appears to receive the proximal 
end of the third so that the second and third 
each have three setae. Vervoort (1957), in 
describing C. maxima , attributes four setae to 
the second segment and two to the third. Gies- 
brecht (1892, pi. 21, figs. 26, 27) indicates 
that in C. longimana Claus the fourth seta is 
between the two segments but in C. bispinosa 
Claus it is on the third segment. This appendage 
is usually regarded as having little diagnostic 
value, but the origin of the fourth seta might 
add a distinguishing character. The fourth, 
fifth, and sixth segments have a pair of setae, 
the distal one in each pair being longer. Distad 
of the sixth segment are two long setae of almost 
equal length. 
The lengths of the third exopodal segments 
of swimming feet 1 to 4 (Figs. 11-14) have 
the following relation to that of their respective 
terminal spines: 1: 1, 2:1, 3:1, and 3:2. 
The symmetrical fifth feet (Fig. 15) are long 
and slender, each ending in two sharp, smooth 
terminal fingers. The inner finger is about four 
times the length of the outer finger. There are 
two external spinous processes located at points 
about one-fourth and two-thirds of the segment 
length from the proximal end of the distal seg- 
ment. There are no internal spines or setae. The 
penultimate segment bears a single seta, and 
the ratio of the length of that segment to that 
of the distal segment is 1 : 4.6. 
Brown pigmentation in the female is 
restricted to the following structures: the fif- 
teenth segment of the first antennae, the setae 
of the second antennae and the mandibular 
palpi, the second segment of the second max-
