Thirty-three specimens belonging to this species were obtained from the plankton col- 
lected at the following stations. 
Stat. 36. — Stat. 81-— Stat. 93. — Stat. 96 (day). — Stat. 96 (night). — Stat. 98. — Stat. 110. — 
Stat. 117%. — Stat. 118 (HENSEN vertical net, 900 metres to surface). — Stat. 128 (HENSEN 
vertical net, 700 metres to surface). — Stat. 133. — Stat. 138. — Stat. 141 (HENSEN vertical 
net, 1000 metres to surface). — Stat. 146. — Stat. 148 (HENSEN vertical net, 1000 metres 
to surface). 
The males and females can readily be separated from the other members of the genus 
by the shape of the terminations of the last thoracic segment, and by the structure of the 
fifth pairs of feet. The dorsal surface of the body is usually quite black. 
Candacia aethiopica appears to have a moderately wide distribution in tropical seas. 
2. Candacia b¢pinnata (Giesbrecht). 
Candace pectinata Brady, 1883 (pars), p. 67, pl. XXX, figs. 1 & 2. 
Candace truncata Brady, 1883 (pars), p. 69, pl. XXIX, fig. 13. 
Candace bipinnata Giesbrecht, 1889, p. 815. 
Candace bipinnata Giesbrecht, 1893, p. 424, pls, 22 & 39. 
Candacia bipinnata Giesbrecht & Schmeil, 1898, p. 129. 
Candacia bipinnata Cleve, 1904, p. 186. 
Candace bipinnata Sars, 1905 (4), p. 5. 
Candacia bipinnata Esterly, 1905, p. 195, fig. 45. 
Seven specimens identical with this species were found in the plankton collected at the 
following stations. 
Stat. 129. — Stat. 203 (HENSEN vertical net, 1500 metres to surface). — Stat. 243 (HENSEN 
vertical net, 1000 metres to surface). — Stat-253. — Stat. 276 (HENSEN vertical net, 750 
metres to surface). — Stat. 282. — Stat. 315. 
The very spiniform wing-like lateral projections of the genital segment, easily distinguish 
the females from those of the other species. Some of the ‘Challenger’ specimens that were 
identified by Brapy as Candace fpectinata, and Candace truncata, undoubtedly belong to this 
species. This is obvious on comparing the illustrations with GrirsBREcHT’s figures. 
Candacia bipinnata has been recorded from the Atlantic and Pacific Oceans. 
3. Candacia btspinosa (Claus). 
Candace bispinosa Claus, 1863, p. 191, pls. XXVII & XXXIII. 
Candace truncata Brady, 1883 (pars), p. 69, pl. XXIX, fig. 11. 
Candace bispinosa Giesbrecht, 1893, p. 424, pls. 21, 22 & 39.
