 3| times. Head 1^ to 1| times as long as broad, its upper surface

 length of the snout, 4 (young) to 8 times in interorbital width ; 

 width of mouth equ.al to or a little less than interorbital width ; 

 band of praemaxillary teeth 4 (young) to 8 times as long as broad ; 

 vomerine teeth granular, forming a crescentic band with or with-
