Adult, — Head above and back vermilion ; ground-colour of the upper 

 half of the sides greenish grey, of the lower and of abdomen silvery; 

 from the occiput a golden longitudinal band bordering the back ; the 

 lateral line bordered above by a crimson, beneath by a golden band ; 

 the scales at the origin of the lateral line broadly edged with crimson, 

 forming a large rounded spot, from which proceeds a straight longitudi- 

 nal crimson band, bordered beneath by a narrower golden band, beneath 

 which four similar parallel bands, gradually lengthening and becoming 

 paler towards abdomen. Infraorbitals silvery crimson, cheeks and oper- 

 cle silvery, posterior half of opercle crimson ; preopercle violet silvery ; 

 caudal rose-coloured ; the other fins transparent white ; dorsal edged 

 with vermilion. Iris golden, upper margin bluish black.

Habit. — Sea of Pinang. 



Madras, Vizagapatam. 



Total length : 6 inch. 



The head is ^ of the total length to the centre of the posterior 

 margin of the caudal ; the greatest vertical diameter of the body 

 equals the length of the head ; the horizontal diameter of the eye is 

 i of the latter ; the eye occupies the second third. The ascending 

 margin of the preopercle is finely toothed, the angle rounded ; on its 

 outer surface as well as on the infraorbitals appear some distant minute 

 pores. The upper lobe of the caudal is longer than the lower, and the 

 third upper ray terminates in a not very long filament, which is also 

 the case with the first ventral ray. 



The following errors occur in Russell's figure. The first dorsal 

 spine is too short, its length in the fish is f of the second. The pec- 

 toral is also too short, its length being equal to that of the head ; the 

 dorsal rays likewise : their length slightly exceeds that of the spines. 

 The anal fin is erroneously represented with one spine : it has three, 

 the first of which is \ of the second, which is but little shorter than the 

 third. The ventral spine is one half the length of the head and equals 

 the 10 th dorsal, which slightly exceeds the preceding. All the spines 

 are very slender and flexible. Single, mostly young individuals occur, 

 but rarely, at Pinang.
