washed with black ; abdomen yellow. Dorsal spines black, the mem-

 band of the body. Caudal fin yellow with a broad black margin, and 

 longitudinally divided by a continuation of the central black band of 

 the body. Anal yellow, lower half as far as the fourth ray black.

Total length : 3| inch. 



The head is contained 4| times in the total length ; the eye is situ- 

 ated a little in front of the second third of the head ; its diameter is 

 a little less than one third of the length of the head. The greatest 

 vertical diameter of the body is J of the length, the caudal fin not 

 included. The first dorsal spine is J of the second, the longest, which 

 slightly exceeds f of the greatest vertical diameter of the body ; 

 the third is a little shorter, the fourth equals half the depth of the 

 body ; the rest gradually decrease, the tenth equalling the first. The 

 second anal spine is remarkably short and slender, its length scarcely 

 exceeding the first dorsal, the second anal is but little shorter and 

 slenderer than the first. The preopercle is very finely toothed ; the 

 opercles terminate in three small membranous points. The caudal fin 

 is nearly rhombic, its length slightly exceeding £ of the total. The 

 pectorals are the shortest fins, their length being contained 6J times 

 in the total. 



The intestinal canal is simple, about J of the total length of the fish ; 

 the stomach is elongated pyriform, the coats thickened : it contained 

 minute shells. There are 5 ccecopyloric appendages, their length is 

 nearly one half of the intestinal canal. The air-vessel is elongated 

 triangular, its length about one third of the total ; from the sides of 

 both its extremities proceed two lateral short, pointed processes, and 

 six equidistant, shorter ones from each side ; its colour is white. A
