 margin of orbit. Body slender, the head very long, the caudal peduncle 

 narrow. Tip of lower jaw but little projecting ; mouth large, the max- 

 illary reaching vertical from posterior margin of pupil, 2J- in head. Upper 

 jaw with teeth laterally in a single series, becoming double anteriorly;
