anterior rays are simple, and the fourth is the longest, the follow- 

 ing ones decreasing regularly in length. Pectoral with a strong 

 fleshy base, the middle rays longest and reaching less than half 

 their distance from the ventrals; the upper ray is not thicker 

 than the others. Caudal deeply forked, the two outer rays broad 

 and simple, the others divided. Adipose dorsal fin triangular, 

 much longer than high, and placed above the hinder part of the 

 anal. 



Colour in formalin. — White, the back and upper part of the 

 head closely speckled with minute blackish dots. A dot is pre- 

 sent at the base of each anal ray, and there are two parallel rows 

 on the belly which unite to form one below the pectorals. Other 

 scattered dots are found on the sides of the body and the fins. 



Described from six specimens, 49-65 mm, long, collected by 

 Mr. Lovefct in the Derwent Hiver, Tasmania. They differ from 

 Johnston's short description only in having the maxillary shorter, 

 and not reaching backward to the middle of the eye. The largest 

 example is figured.

Two specimens, 163-170mm. long, differ greatly in their colour- 

 marking. One, a male, is brown, variegated with irregular 

 bluish blotches which are largest on the back; the back is crossed 

 by sixteen broad bars, and the sides of the abdomen are marked 

 with curved lines of bluish dots. 



The other, which is figured, is much lighter, and the cross- 

 bands are less distinct; the sutures have a brown spot at each 

 angle, and the abdomen is crossed by narrow brown bands. The 

 sides and back are closely covered with reticulating brown lines, 

 and the lower parts of the head and the breast bear numerous 

 deep brown dots.
