Candacia — GRICE and JONES 
287 
on lobes 3 and 4 of the second maxillae, much 
of both rami of swimming feet 1 to 4 including 
several setae on the second and third exopodal 
segments and second endopodal segment, and 
the first basipodal segment of the fifth pair of 
feet. 
The adult male (Figs. 36, 37) is slightly 
smaller than the female. The right posterior 
lateral process of the fifth thoracic segment is 
produced posteriorly and curved inward in dorsal 
view (Fig. 38). It reaches to the middle of the 
protrusion on the genital segment. In lateral 
view, the thoracic process has a decided upward 
bend (Fig. 39). The genital segment has a 
bilobed protrusion arising from near the poste- 
rior end of the right margin (Fig. 38). The 
abdominal segments and furca have the follow- 
ing ratios (based on three specimens): 22, 24, 
20, 13,9, 12 = 100. 
Segments 17, 18, 19, and 20 of the right 
first antenna (Fig. 40) are separate, with 17, 
18, and 19 toothed. The nearly uniform teeth 
on segment 18 are coarser than those on seg- 
ments 17 and 19. The fifth feet are shown 
in Figure 41. 
The following body parts and appendages of 
the male are pigmented (based on examination 
of several specimens): segments 17 to 25 of 
the right antenna, the distal 17 segments of the 
left antenna, the process on the right corner of 
the fifth thoracic segment, the clawlike spine 
on the distal part of the first inner lobe of the 
first maxillae, portions of the first basipod and 
spines on lobes 3 and 4 and the five large distal 
spines of the second maxillae, basipodal seg- 
ments 1 and 2 of swimming feet 1 to 4. 
REMARKS: The female of C. guggenheimi 
superficially resembles C. longimana Claus. The 
spines on the dorsal surface of the genital seg- 
ment, the structure of the fifth pair of feet, and 
the somewhat smaller size of this species readily 
distinguish it from C. longimana. The bilobed 
protrusion on the genital segment and the struc- 
ture of the fifth feet serve to distinguish the 
male. This species is named for the late Simon 
Guggenheim, one of the founders of the John 
Simon Guggenheim Memorial Foundation.
