This species resembles semicinctus of Richardson ; but has a 

 blunter head, shorter pectorals, which are broader than long, and 

 diffei's, moreover, in its markings. On the head there are several 

 rows of white spots, edged with black ; three on each side behind the 

 eyes, six between the anterior corner of the eyes, and four on the 

 snout, Avhose tip is spotted with black, and its medial line white. On 

 the mandible there are two rows of spots, less distinct. There are 

 three large spots on the occiput, whose median region is whitish, 

 with dark spots. Twenty-nine ocellated spots occur on the back. 

 Under the lateral line there are twenty-three such spots, alternating 

 with the upper ones ; but all of them have not the white centre. 

 The yellowish dorsal fin has black spots on its edge ; and the anal, 

 which is coloured yellowish like the belly, is without spots. The

The nasal teeth, about 83 in number, are disposed on a convex 

 oval disk, which is not separated from the vomerine teeth by a 

 distinct line. The latter run far back, and anteriorly stand in two 

 rows, in the middle in four, and again in two posteriorly. The 

 palathie teeth form two or three irregular rows, which are increased 

 to four near the symphysis. The dorsal commences about an inch 

 before the gill-opening, and, together with the anal, carries its
