 Olive green above, silvery below; a silvery lateral stripe; a dark

 moderately depressed, not keeled. Head long, flat above, witli a 

 broad, rather shallow, scaly median groove. Top of head not rugose, 

 usually faintly striate. Maxillary rather more than half hidden by the 

 preorbital. Teeth moderate; no vomerine teeth. Gill-rakers obsolete. 

 Body subcylindrical, its depth less than the length of the pectoral, 

 which is about equal to the postorbital part of the head. Ventrals a 

 little nearer the head than the caudal ; dorsal and anal somewhat fal- 

 cate; caudal fin truncate, or slightly emarginate. Scales thin and 

 small, deciduous. Head 2f ; snout 4. D. 15; A. 18. L. 4 feet. Maine
