Very small spines cover the whole body from the snout to the 

 space between the dorsal and anal fins, the hind part of the tail 

 being naked ; abdominal spines with two, three, or four short 

 roots. Two solid nasal tentacles without opening on each side. 

 Snout of moderate length, with the upper profile slightly 

 concave. Orbit prominent, situated in the middle of the length 

 of the head. Inter-orbital space concave, not twice as broad as 

 the orbit. Length of the caudal fin equal to its distance from 

 the front margin of the dorsal. Brown above with not very 

 numerous rounded bluish- white spots. One or two bluish rings 

 round the gill-opening, pectoral fin, and orbit. The lower parts 

 of the sides are variously marked with either blotches or vertical 

 or longitudinal bands or stripes. 



Port Jackson. Length twenty inches.

Small two-rooted spines cover the entire body, except the 

 snout and the posterior part of the caudal peduncle ; there are 

 about fifty spines in a longitudinal series between the nostril 

 and dorsal fin. Two solid nasal tentacles without opening on 

 each side. The length of the snout is contained twice and two- 

 thirds in that of the head, and is a little less than the width of 

 the inter-orbital space, which is rather convex. Greyish above, 

 lighter below, all parts with ovate white spots, smaller than the 

 eye, and than the interspaces of the ground colour. 



Port Jackson. Length eleven inches.
