spines occur on the distal margin of the 6th segment. The telson in 

 females is 3/5, in males 1/2 the length of the basipodite of uropods III. 

 Distribution: This species is found in tropical and equatorial regions 

 of the Pacific Ocean. It is common in the upper 200-m layer during the 

 day but at night at the very surface. 



3. Lestrigonus crucipes (Bovallius, 1889) (Fig. 164) 



Bovallius, 1889: 225 (Hyperia); Laval, 1968a: 64 (Hyperia); Bow- 

 man, 1973: 43. 



Body length about 4 mm. 



The body is thickset. Somites I-III of the pereon are fused in females 

 but only somites I-II in males. 



Compared to other species of the genus, antennae I and II are well 

 developed; the cone of the antennal gland is obtuse, its apex directed 

 forward and sidewards. The mandibles have a broad dentate process. 

 The inner lobe of maxillae I bears five apical spines. The outer lobes of 

 the maxillipeds have three spines along the inner margin and two apical
