The natatory, biramous second antenna carries a simple endopod. 



The first and second maxillae are visible and the bifurcate first cormopod is present. 



The first segment of the abdomen bears one pair of non-setose pleopods. 



The telson is elongated and the uropods are well developed. The telson carries seven terminal 

 spines, three pairs of postero-lateral and one pair of ventro-lateral spines. 



F'g- I 5- Euphausia lucens. a, first furcilia, lateral view; b, cephalothorax, dorsal view; c, telson and lateral uropods; d, second 



antenna ; e, first maxilla ; /, second maxilla ; g, first cormopod. 



Second furcilia. Three specimens were found (Fig. 160, b). The average length was 3-5 mm. 

 The anterior margin of the carapace has narrowed to a finely serrated frontal plate. The posterior 

 margin is no longer produced as a dorsal spine, but the inferior margin retains its denticle. 

 The rather small eyes project considerably beyond the margins of the frontal plate. 

 The first and second antennae are unchanged.
