Cymothoa oeuJafd Say is probably identical with ^'E<j<(t]i(>a lolkjhiea 

 Harger. In the description given b}' Say, the characters which point to 

 this identification are " body elongate oval; head trilobate behind, mid- 

 dle lobe smallest: abdomen, segments not shorter than terminal thoracic 

 ones; tail, terminal segment shorter than the four preceding segments 

 conjunctly. Lateral line of body forming a perfectly uninteri-upted 

 curve; head regularly rounded before, broader than long; eyes large, 

 conspicuous, fascets regularly hexagonal; terminal segment hardly 

 broader than preceding segment, rounded at tip, edge ciliate, nearly 

 equal to length of the four preceding joints conjunctly. Uropoda 

 ciliated."
