 the base a cobalt blue longitudinal band, above which a second parallel 

 lilac one terminating on the anterior third of the fin ; a third and a 

 fourth above each other: both bifurcating about the anterior half ; 

 upper margin black ; anterior half of caudal white, the rest brown like 

 the body ; posterior margin broad, black ; anal bright yellow minutely 

 dotted with brown, with a cobalt blue basal band, above which four 

 parallel lilac ones, external margin black ; ventral spine and rays pale 

 bluish black ; membrane pale grey minutely dotted with brown ; pec-

Total length : 5f inch. 



The length of the head is 4 J in the total ; the diameter of the eye is 

 ?>\ in the length of the head. The preopercle, opercle, scapular and 

 humeral bones are distinctly radiated. In each jaw is a single series of 

 16 trenchant teeth : those of the upper appear somewhat larger and their 

 margin has from 10 to 12 crenulations (Fig. 3. Magnif.) ; in the lower 

 jaw the pair of teeth on the symphysis is longer than the rest, and the 

 whole of the margin carries 10 crenulations; all the rest are shorter, 

 truncated with about 5 crenulations. The greatest vertical diameter of 

 the body (Fig. 2.) is 2\ in the total length. The whole of the head and 

 body, the anterior half of the caudal and the base of the dorsal and anal 

 fins, are covered with small elongated oval scales (Fig. 4. Magnif.), of 

 which those of the body have the posterior part truncated with about 

 12 unequal cilia on the margin. The lateral line appears like a thread 

 at the upper fifth of the body ; it is slightly undulating, following the 

 outline of the back, which is less arched than that of the abdomen, till 

 it arrives between the terminations of the dorsal and anal fins. From 

 thence it is at first a little downwards arched and then rises, so as to 

 pass above the spine of the tail towards the caudal. Above and below 

 the lateral line appear a number of short, excessively minute, backwards 

 directed tubes. The length of the spine is less than the diameter of 

 the eye ; the anterior margin is sharp, the posterior rounded. The 

 posterior margin of the caudal is slightly concave; the superior
