One female belonging to the above species was found in the plankton collected at each 
of the three following stations. 
Stat. 110. — Stat. 128 (HENSEN vertical net, 700 metres to surface). — Stat. 133. 
The genital segment of the female is considerably expanded at the distal end. Each 
side of the segment is produced into a small spine. Brapy considered that this form was only 
a variety of Candacza truncata, but the spiniform projections of the last thoracic segment, and 
the shape of the genital segment of the females clearly shew that it is quite distinct. 
Candacia btspinosa has been recorded from the Atlantic and Pacific Oceans, and from 
the Mediterranean.

This species appeared to be fairly well distributed throughout the area investigated. 
Forty specimens were obtained from the plankton collected at the following stations. 
Stat. 37. — Stat. 47°. — Stat. 66. — Stat. 75 (HENSEN vertical net, 11 metres to surface). — 
Stat. 93. — Stat. 96 (day). — Stat. 96 (night). — Stat. 98. — Stat. 101. — Stat. 121. — 
Stat. 125. — Stat. 138. — Stat. 143 (HENSEN vertical net, 1000 metres to surface). — 
Stat. 146. — Stat. 148 (HENSEN vertical net, 1000 metres to surface). — Stat. 185 (HENSEN 
vertical net, 1536 metres to surface). — Stats. 19g4—7. — Stat. 215°. — Stat. 217 (horizontal 
cylinder). — Stat. 220 (surface). — Stat. 220 (HENSEN vertical net, 200 metres to surface). — 
Stat. 225. — Stat. 276 (HENSEN vertical net, 750 metres to surface). — Stat. 282. — 
Stat. 304. — Stat. 315. 
The structure of the fifth pair of feet of both sexes readily separates this species from 
the other members of the genus. | 
One of the illustrations given on plate X XIX in the report on the ‘Challenger’ Copepoda, 
as the female fifth pair of Candace truncata clearly belongs to Candacza catula. 
Candacia catula has been recorded from the Atlantic, Indian and Pacific Oceans.
