Otago Museum. It differs from Therapon in the oblique cleft 

 of the mouth, the forked caudal, and the greater development 

 of the scales on the vertical fins ; but I hesitate to draw up 

 generic characters for it until I can get a fresh specimen.

Length twice and one fourth the height, or three times the 

 length of the head ; snout about half the diameter of the eye, 

 which goes twice and two thirds into the length of the head. 

 Maxillary extending to posterior part of the orbit, dilated at the 

 end. All the teeth on the jaws, palate, and vomer very small. 

 Interorbital space convex, equal to the diameter of the eye. 

 Scales ending before the middle of the eye. Nostrils and ridges 

 on the top of the head as in T. elongatus. Snout with two spines 

 directed forward, one from each ridge. Infraorbital slightly 

 crenated along its inferior margin. Prseoperculum divided 

 by a deep channel, which is crossed at the angle by a strong, 

 rough, projecting spine, which extends to the gill-opening. 

 Operculum with radiating rough ridges and a single spine. 

 Cheeks scaly. Scapular bone with a spine equal to that on 

 the operculum. Spines of the dorsal short and smooth ; the 

 third soft ray the longest, and as long as the pectorals, which 

 are rounded and one fifth of the length of the body. Caudal 

 forked, composed of twenty-two soft rays, with seven spines 

 above and six below. Spines of the anal small. Ventrals 

 situated on either side of the vent, slightly behind the pectorals ; 

 they extend back to the end of the pectorals ; ventral keel 

 with eleven scales, each armed with a strong spine directed 

 backward. 



Colour greyish yellow ; fins yellow. 



Total length of the specimen 1\ inches.

 to the Otago Museum, and after whom I have much pleasure 

 in naming it.

Length four times and a half the height of the body, or 

 three times and a half the length of the head ; breadth of 

 the head equal to the height of the body ; interorbital space 

 rather more than twice the diameter of the eye. Top of the
