Leno-th of head from 4/13 to 1/4, of pectoral 1/2, of caudal 1/4 to 1/5, height of body 2/3 to 3/4 of the 

 total length. Ez/es— diameter from 3/7 to 1/3 of the length of head, 1 to U diameters fi-om end of snout, and 

 2/3 to 3/4 of a diameter apart. Dorsal profile considerably elevated, the abdominal much less curved. 

 Mouth smaU, the maxilla extends to below the first third of the orbit. Preorbital high, its depth generally 

 exceeding the diameter of the eye. Preopercle with a few serrations on its lower limb : sub- and mter-opercles 



' In young specimens the upper edge of the orbit and the upper edge of the occipital process are serrated, 

 whilst there exist about eight strong teeth along the horizontal limb of the preopercle. In a very young 

 specimen (U inches long), in addition to the foregoing, an elevated roughened ridge passes from the upper 

 hind edge of the orbit to the lateral-line. ■ j ■ • i 



Fins— dorsal spines strong, and considerable differences are perceptible, m a young mdmdual (at Ifg 

 inches lono-), the last six are of equal height. Should there be nine dorsal spines, the fourth is the longest m 

 the adult •'^if only eight then the third : this spine equals the length of head behind the middle or front edge of 

 the eye • 'interspinous membrane deeply notched, and the rays longer than the spines : pectoral sometimes 

 reachincr to the base of the caudal : second anal spine the strongest and generally the longest : caudal with its 

 central rays slightly produced. Colours— silvery, having a gloss of gold and tmge of pui-ple, with or without 

 vertical bands and black spots : edges of the fins stained with grey, and a similar band along the middle of the 



dorsal. , . , , , , i ... , ^j, 



The D. punctata has been considered a distinct species, and it may be that such an opinion is correct.* 

 At U inches in length is the earliest age at which I have seen distinct spots existing on the vertical body bands. 

 Out of twelve specimens of this variety, and in which every individual is distinctly spotted, nine dorsal spmes 

 invariably exist, as given by Russell, and in Cuv. and Val. vii, pi. 179. . , ■ i , i ■, , ■ t.^ 



In D longimana, the black spots are absent, and out of eleven specimens examined, eiglit had only eight 

 dorsal spines, the number given by RusseU, whilst the horizontal one before the dorsal fin was as a rule more 

 apparent than in the other variety : in some of the remainmg three the spots may have disappeared. 



In the very young the fish are covered all over with minute dark spots giving them a grey appearance. 



Jerdon observes that D. punctata is termed PooU tarate, and D. longlmana, S'lpu tarate. M. J. L. and S.
