Specimens of this very characteristic species were found in the plankton collected at 
the following stations. 
Stat. 66. — Stat. 99. — Stat. 121. — Stat. 141 (HENSEN vertical net, 1500 metres to sur- 
face). — Stat. 142. — Stat. 185 (HENSEN vertical net, 1536 metres to surface). — Stat. 220 
(HENSEN vertical net, 200 metres to surface). — Stat. 252. — Stat. 276 (HENSEN vertical 
net, 750 metres to surface). — Stat. 282. 
The furcal joints are narrowly quadrangular in shape and are about twice as long as 
broad. Two of the apical setae are leaf-like in structure. 
Sapphirina metallina has been recorded from the Atlantic, Indian and Pacific Oceans.

Sapphirina maculosa A. Scott, 1902, p. 419. 
One specimen belonging to this species was found in the plankton collected at each 
of the following five stations. 
Stat. 36. — Stat. 37. — Stat. 47°. — Stat. 66. — Stat. 225. 
The furcal joints are elongate ovate in shape and are about twice as long as broad. 
The apex is narrowly rounded. The inner margin terminates in a small tooth. 
Sapphirina maculosa has been recorded from the Mediterranean and Red Sea, and 
from the Atlantic Ocean.

This species appeared to be fairly well distributed in the area investigated by the 
‘Siboga’. It was present at twenty stations as shewn.
