One female belonging to the above species was found in the plankton collected at each 

 of the three following stations. 



Stat. 110. — Stat. 128 (Heksen 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. Bradv considered that this form was only 

 a variety of Candacia 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 bispinosa 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 1 . — Stat. 66. — Stat. 75 (Hensen vertical net, 1 1 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. 194 — 7. — Stat. 2 1 5 : '. — 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 XXIX in the report on the 'Challenger' Copepoda, 

 as the female fifth pair of Candacc truncata clearly belongs to Candacia catula. 



Candacia catula has been recorded from the Atlantic, Indian and Pacific Oceans.
