Length of head 2/7 to 1/3, of pectoral 2/11, of caudal 1/5, height of body nearly 1/3 of the total length. 

 Eyes — diameter 2/7 to l/4 of the length of head, 3/4 of a diameter from end of snout, and 1 apart. Body 

 oblong and elongated, sometimes with a slight concavity in the profile above the orbit : lower jaw the longer. 

 The maxiUa extends to -below the hind edge of the orbit. Vertical limb of preopercle with three spinate 

 denticulations on its border, the upper being the smallest ; some indistinct ones along the lower limb. Three 

 spines on opercle. A rudimentary barbel on the lower jaw, which in a fresh specimen, nearly 4 inches long, 

 equalled half the length of the orbit. Teeth — ^viUiform in jaws, vomer, and palate. Fins—Aihiri dorsal spine 

 the longest equalling one-third of the height of the body below it : soft dorsal, anal, and caudal rounded. 

 Scales — ^imbedded in epidermis and usually covered with mucus. Colours — of a deep chestnut brown, with three 

 milk-white longitudinal bands, from the head along the body, the inferior ceasing opposite the posterior end of 

 the base of the anal fin. A white median band from the snout to the base of the dorsal fin. 



In some specimens there are six or more white longitudinal lines along either side of the body. 



Seba figures this fish as Grammistes, pi. 27, f. 5. . 



Habitat — Seas of India, to the Malay Archipelago, and beyond, attaining only a few inches in length. 

 The one figured is from the Andamans, and life size. 



Genus, 7— DiPLOPEiON, (Kuhl. and v. Sass.) Guv. and Val. 



Branchiostegals seven : pseudobranchice. Body oblong, compressed. Eyes lateral. Opercle spinate : preopercle 

 with a double edge, the outer of which is denticulated. Teeth villiform in jaws, voiner, atid palaiines, no canines : 

 tongue smooth. Two dorsal fins, the first with eight spines : anal with two. Scales small, adherent. Pyloric 

 appendages few. 



Geographical distribution. — ^Prom the seas of India to China and Japan. This fish I have not personally 

 captured in India, nor foimd it in local Indian collections ; those taken have been probably mere stragglers. ■ 

 Dr. Jerdon remarks, "this pretty fish is rare at Madras." — (Madr. Journ. Lit. and Science 1851 No 39

Length of head 2/7, of caudal 1/5, height of body 2/5 of the total length. Eyes — diameter 1/4 length of 

 head, Ij diameters from end of snout, and 3/4 of a diameter apart. The masUla reaches to below the middle of 

 the orbit. Preopercle having a double edge the outer of which is serrated, the inner ridge is also stated to be 

 sometimes serrated. Approximating portions of sub- and inter-opercles serrated. Opercle with its two upper 

 spines large, followed inferiorly by several smaller ones. Teeth — generic. Fins — third and fourth dorsal 

 spines the highest, and nearly equal to the length of the head behind the front edge of the orbit ; they decrease 



in length to the last which is very short : anal spiaes also very short : caudal rounded. Colours Gamboge 



yellow vrith two broad black cross bands. 



Habitat — Seas of India, to China and Japan.
