is shorter than any behind it ; the third is equal to the penultimate one. The posterior 
part of the soft is higher than the spinous portion. The distance between the dorsal 
and caudal is less than the height of the tail below the former. The caudal is very 
slightly forked, and is scaly at the base. The anal commences below the second, and 
extends to below the seventh dorsal ray ; the two last spines are nearly equal in length, 
but the second is the stronger, they are about one-third of the length of the head ; the 
first is less than half of the two succeeding ones ; the soft portion is lower than the soft 
dorsal. Scales rather small.
