Galaxias divergens Stokell, 68 mm , Mountain Camp Stream, Pelorus River System. in head length, and usually fewer caudal and pelvic fin rays. The difference in jaw form immediately separates the two species. Description. Trunk rounded to squarish in section, dorsally flattened with moderate development of a middorsal furrow, trunk profiles somewhat parallel, tapering an- teriorly to a small head and becoming slender posteriorly. Caudal peduncle very long and generally slender, depth about half length. Lateral line an inconspicuous midlateral groove; accessory lateral line not observed. Head short, broader than deep, head depth conspicuously less than body depth. Eye small, towards upper head profile, and interorbital flat. Jaws equal or lower a little shorter, short in head length; cleft moderately oblique and reach- ing to about anterior eye margin; jaw pro- file from ventral aspect broad and shallow, somewhat flattened anteriorly. Jaws with- out canines, mesopterygoidal teeth weak; pyloric caeca lacking; gill rakers reduced to indefinite stubs. Dorsal and anal fins small, somewhat fleshy at bases but membranous distally; short based and extending little beyond bases, distal margins rounded. Dorsal origin well forwards due to length of caudal peduncle, anal origin below or a little be- hind dorsal origin. Pelvic fin inserted at about midpoint of standard length; pelvic- anal interval moderately long, fin very short in interval. Pectoral fin inserted moderately high laterally; short in pectoral- pelvic interval, which is also rather short; distal margin of pectoral fin rounded, with middle rays longest. Caudal fin moderately long, emarginate, depth about equal to body depth; flanges of peduncle weak to moderate. Variation. Meristic: dorsal 7 (9), 8 (58), 9 (34), 10 (10); caudal 13 (1), 14 (3), 15 (83), 16 (6); ana
