AMMOTRETIS Giinther, 1862. 
Two species of this genus were taken, one of which is regarded 
as undescribed. The three known species may be _ thus 
distinguished :— 
a. Ctenoid scales on both sides of body, dorsal 
and anal fin rays sealy ‘ rostratus. 
aa. Ctenoid scales on right side of ‘body only, 
no scales on dorsal or anal fin rays 
b. Rostral hook very long, interorbital space 
wide, body with large blotches pe nudipinnis. 
bb. Rostral hook small, interorbital space 
narrow, body with spots forming lines guntheri, 
A. rostratus is an Australian and Tasmanian species. A. 
nudipinms and A. gunthert are known only from New Zealand.

The rostral hook is very long, extending downwards below 
the level of the maxilla, mouth large; lower lp with a fringe 
of ten rays on the right side. Eyes on the right side on the 
same level, interorbital space wide, equal to the longitudinal 
diameter of the eye: gill membranes not broadly united below, 
oill rakers short. 
Teeth—A broad band of small teeth in each jaw on the left 
side only. 
Fins—The dorsal rays commence at the tip of the rostral 
hook, the first five or six are free, the longest rays occur between 
the 36th and 46th, and, measured from the edge of the sheath 
on the right side, are contained three times in the head: the
