Chirocentvodon bleekerianus, jaw dentition, from a specimen 85*1 mm Scales : completely deciduous. Colour : body a uniform light or rich brown with a faint indication of a lighter (silvery) lateral band about three-quarters eye diameter in width following the line of the longitudinal muscle of the flank. (Silvery band still visible in syntypes of C. taeniatus Giinther, BMNH ). Fins hyaline except for narrow subcutaneous dark line at base of caudal and a speckling of melanophores on caudal rays. Note. Jordan & Seale (1926) hinted at a relationship between Chirocentvodon ( their Medipellona) and the Engraulidae, based on the presence of canine teeth, the arrangement of the fins and the silvery lateral band in Chirocentvodon. Canine teeth certainly occur in the engraulid Lycothrissa crocodilus Bleeker, but they are also present in the clupeid genera Cynothrissa and Odaxothvissa (Pellonulinae) ; the fins of Chivocentvodon are more typical of Ilisha and other members of the Pristi- gasterinae ; and a silver lateral band is found in many clupeids ( Lite). The Engraulidae can be separated from the Clupeidae on the following five features : a. Mesethmoid prominent, projecting in front of vomer to form 'pig-like' snout (but snout clupeid-like in Anchoviella bvevivostvis - see p. 155).
