The femalc of this species is moderately broad. The furcal joints are oval in shape 

 and are nearly twice as long as broad. Each joint terminates in a sharp pointed apex which 

 and readily distinguishes the species from any of the other known members of the genus. 



Sapphirina sinuicauda has been recorded from the Atlantic, Indian and Pacific Oceans, 

 and from the Mediterranean.

This proved to be the most common and widely distributed member of the genus. It 

 was represented at the following stations in the area traversed by the 'Siboga'.

The female is moderately broad. The furcal joints are elongate ovate in shape and are 

 about twice as long as broad. The apex of each joint is rather narrowly rounded. The distal 

 end of the inner margin is produced into a distinct tooth. 



Sapphirina stellata has been recorded from the Atlantic. Indian and Pacific Oceans.

Female — length 5.5 mm. 



Seen from above, the body appears moderately elongate and narrow. lts length, in- 

 cluding the furcal joints, is three and a half times longer than broad. The abdomen is distinctly 

 narrower than the thorax. The furcal joints are comparatively long and narrow. Each joint is 

 three times longer than broad. The outer margin of the joints is nearly straight. The inner 

 margin is considerably inflated at the proximal end. The distal end of the outer margin is 

 notched. The inner margin terminates in a small tooth. The outer margin is entirely without 

 setae. The joints are furnished with a single seta placed at the apex (Plate LXIX, fig. 15). 



The antennules are short and five-jointed. The second joint is considerably longer than 

 any of the others. The fourth joint is short (Plate LXIX, Fig. 16).
