The length of the head is \ of the total ; the distance from the sym- 

 physis of the lower jaw to the nostril is \ of the length of the head, of 

 which the diameter of the orbit is \. From the middle of the supra- 

 orbital margin rises a small backwards directed spine; the distance 

 between both is less than the diameter of the orbit. From the poste- 

 rior margin of the orbit radiate numerous lines over the opercles. 

 The occiput carries a crest, surmounted in front by a tubercle, behind 

 by five minute spines ; at the root of the pectorals, and on each side 

 of the throat appears a small backwards directed spine. The body is 

 heptagonal, its greatest vertical diameter slightly exceeds \ of the 

 length of the head ; the tail is quadrangular, tapering into a point. The 

 anus is situated nearly in the middle of the total length, and opposite 

 the middle of the dorsal. The latter occupies the 10th and 11th ring 

 of the body and the first of the tail ; all three rings are arched, so as to 

 appear like a crest from which the dorsal rises. The length of the 

 rays is a little less than two diameters of the orbit ; the extent of the 

 base is f of the length of the head. The pectorals are a little shorter 

 than the dorsal ; the anal is about half the diameter of the orbit. One 

 individual was observed at Pinang in September 1842 ; a second in 

 January 1844.

Brownish buff ; opercles bluish ; round the orbit a few distant brown 

 dots ; fins hyaline. Iris silvery white with a number of short brown- 

 ish lines radiating from the pupil.

The length of the head slightly exceeds £ of the total ; the distance 

 from the symphysis of the lower jaw to the nostril is f ; the diameter 

 of the orbit is ^ of the length of the head. All the spines of the sali- 

 ent angles are surmounted by oval or rounded tubercles. On the fore- 

 head between the eyes appears a single spine ; on each supraorbital
