these specimens. The first dorsal is dark brown and has a light edging. Second 

 dorsal, pectorals, and caudal have transverse series of small elongate spots of 

 brown. The ventral disk is similar to that figured by Pallas on his type, from 

 Amboyna. On immature specimens of an inch and a quarter in length the 

 disk is as perfect as on the large ones.

The fishes placed here were captured on the Great Barrier Reef, Australia. 

 Apparently of a single species, they exliibit a wide range in variation. Tlie 

 rays in the first dorsal number seven in the smallest individuals, and eight, 

 nine, ten, and fourteen on larger ones. The largest have a black band in the 

 upper half of the same fin ; it is represented by a black spot on the hinder rays 

 in the smallest of the lot. There are seven or eight scales between the dorsals 

 on the larger and nearly twice as many on the smallest specimens. Commonly 

 there are seven or eight bands of brown separated by spaces of lighter color 

 about equal in width, crossing the back and passing down and forward on the 

 flank. The ventrals are separate at all ages.

Outlines in some degree resembling those of B. maoricus Kner, 1867, but the 

 head is more pointed and less convex in the frontal region, and the filament 

 above the orbits is shaped differently. Body compressed, robust, depth erjual 

 to length of head and contained three and two-thirds times in the length with- 

 out the caudal. Head short, blunt-pointed at the snout, with a low arch above 

 the orbits. Snout short, half as long as the eye. Mouth medium, cleft rising 

 slightly forward, maxillary reaching below the anterior one-fourth of the eye. 

 A canine on each of the lower jaws and two smaller ones near the symphysis 

 on each upper jaw. Eye large, less than three times in the length of the head. 

 A short slender filament above each eye (not shown in figure) ; no filament 

 and no crest on the nape ; a short nasal filament on each side. Dorsal 

 notched, spinous portion originating above the base of the pectoral; rays in 

 spinous portion shorter. Pectorals broad, rounded on hind margin. Caudal 

 slightly notched, little shorter than the head. Lateral line extending to a 

 point below the first spine of the second dorsal. 



Color uniform light brownish, white or yellow ; a brown band across the 

 occiput from eye to eye ; a brown spot above the orbits.
