ward the ventral surface; a genital process on the midline between 



the ventral processes. First antennae 4-segmerited ; exopod of sec- 

 ond antenna 2-segmented ; second maxillae 

 short, separate to their tips, bulla spherical. 

 Length of cephalothorax, 2.15 mm.; of 

 trunk, 4.5 mm. 



Male. — Head with dorsal carapace, sepa- 

 rated from trunk by a short neck; trunk 

 spindle-shaped, ending in a conical median 

 process; no caudal rami. First antennae 

 4-segmented; exopod of second antenna 2- 

 segmented, with an apical tuft of setae; 

 second maxillae exceptionally long and 

 slender, more than twice the length of the 

 maxillipeds, which are stout and triangular. 

 Total length, 1.35 mm. 



Reinarhs. — In both sexes of this species 

 the head, neck, and trunk are in line with 

 one another. The host is a southern fish
