Pharyngeal bone well developed and robust, its pitted surface broad with three large fos- 

 sae. Posterior limb short, strong, and bent anteriorly. Anterior limb slender, narrower po- 

 steriorly, and expanding at anterior end. Pharyngeal teeth in one row, 5-5. Teeth strong, 

 hooked at tip. 



Vertebrae 37; precaudal vertebrae 20, caudal vertebrae 17. 



Intestine long, with about 3.5 loops. Its length 193% of standard length. Gas bladder broad 

 and relatively short. Anterior chamber round at anterior end, and almost equal in width 

 for whole chamber. Posterior chamber almost equal in width from anterior to posterior 

 ends. Anterior chamber 70% of posterior chamber in length. Constriction short and broad. 

 Pneumatic duct placed at middle of the constriction. Peritoneum dark. 

 Tuberculation. Male Whole head, including its dorsal, lateral, and ventral sides, bea- 

 ring tubercles. Tubercles on head small and short. Dorsum of head bearing higher density 

 of tubercles than rest of body. Each scale in 10 or 11 rows on the breast bearing two to 

 four tubercles on its apical margin, forming comb-like edge. All tubercles in this region 

 similar in size and shape. Dorsal, lateral, and ventral sides of the body bearing tubercles. 

 Each scale bearing one or two small, short tubercles near center of the scale, except in 

 ventrolateral portion of the caudal peduncle. Every scale on the ventrolateral part of the 

 caudal peduncle bearing one row of four to six well-developed tubercles on apical mar- 

 gin. 



All fins except caudal fin bearing tubercles. Pelvic, dorsal, and anal fins, and ventral side 

 of the pectoral fin have few small, short tubercles on fin rays and membrane. On pecto- 

 ral fin, dorsal side of the second to seventh fin rays bearing two rows of well developed, 

 sharp tubercles on its distal portion, decreasing to one row proximally. Proximal one-third 

 of pectoral fin without tubercles. Few small tubercles on interradial membrane of pecto- 

 ral fin. 



Female Females bearing very small tubercles, hardly descendible with naked eye. Ante- 

 rior end of snout tuberculated. Entire lateral and ventral sides of body bearing tubercles. 

 Each scale in these regions bearing one or two small tubercles near center of scale. Pec- 

 toral, pelvic, dorsal, and anal fins bearing few small tubercles on both membrane and rays. 

 Coloration. Two distinct lateral black stripes present on the flank. Lower one longer 

 and broader than upper one. Lower lateral stripe extending uninterrupted from anterior 

 end of snout to base of caudal fin; the stripe broader at middle portion of body. Upper la- 

 teral stripe originates dorsal to posterior margin of opercle, and extends to posterior por- 

 tion of caudal peduncle, but not reaching caudal fin base. Upper lateral stripe almost equal 

 in width along its length, but interrupted in its posterior portion, forming a series of dots. 

 A few small speckles (smaller than pupil of eye) occur dorsal to the upper lateral stripe. 

 In females, the lateral stripes narrower and fainter than that in males, especially upper la- 

 teral stripe. Body dorsum darker than flank, bearing a mid-dorsal dark stripe. Dorsal stripe 

 originating at nape and extending to posterior end of body. In most specimens studied, 

 the dorsal stripe is continuous posterior to dorsal fin, but is interrupted in three specimens. 

 No melanophores on ventral side of the body, except the breast area in males bearing 

 some melanophores. In female, lateral body, as a whole, paler than in male.
