 complete or incomplete. Five known species, of which the 2 following are 

 recorded from North Carolina : 



i. Scales very small, about 100 in lateral series; snout moderately long; gill-membranes 

 slightly connected; general color of body olive green tinged with orange; a lateral band of 

 confluent elongated blotches and a long row of small, discreet brown spots between
