The forms belonging to this species although less numerous in the plankton than the 

 representatives of the previous one, were found to have a moderately wide distribution in the 

 area investigated, as shewn by the following records.

This Temora has a very close resemblance to Temora longicornis (Muller), found in the 

 plankton of the Xorth Atlantic, off the coast of Europe, and can only with difficulty be separated 

 from it. It may simply be a tropical variation of the well known northern form. 



Genus Temoropia T. Scott, 1893. 



This genus is separated from the other members of the family by the structure of the 

 fifth pair of feet of both sexes. The fifth pair of the female is not quite symmetrical in the 

 type form, but it is quite symmetrical in North Atlantic examples of a nearly related species. 

 The female fifth pair is represented by two free joints attached to a basal part. The first free 

 joint is furnished at its inner distal angle with a spiniform process, which may represent a 

 rudimentary endopodite. The male fifth pair is large and conspicuous. 



One species was obtained from the plankton collected by the 'Siboga'.

The typical member of the genus was rather rare in the area investigated. Males and 

 females were obtained from the plankton collected at the following stations. 



Stat. 35, 2 specimens. — Stat. 143 (HENSEN vertical net, 1000 metres to surface), 6 speci- 

 mens. — Stat. 148 (HENSEN vertical net, 1000 metres to surface), 4 specimens. — Stat. 184, 

 3 specimens. — Stat. 185 (HEXSEN vertical net, 1536 metres to surface), 1 specimen. — 

 Stat. 203 (HENSEN vertical net, 1500 metres to surface), 8 specimens. — Stat. 220 (HENSEN 

 vertical net, 200 metres to surface), 4 specimens. — Stat. 243 (HENSEN vertical net, 1000 

 metres to surface), 4 specimens. 



Temoropia mayumbaensis is a very characteristic form and is readily recognised by the 

 structure of the fifth pair of feet of both sexes. The ventral surface of the genital segment of 

 the female is greatly inflated. Length, female .94 mm., male .9 mm. 



This species has hitherto only been known from the Gulf of Guinea and from the Gulf of Suez.
