. Bulletin of the Museum of Comparative Zoology at Harvard College. Zoology. New Zealand Galaxiidae • McDowall 403. i Figure 37. Neochanna diversus Sfokell, 112 mm , swamp at Waiharara, North Auckland District. Median fins moderately long based and expansive, but extending little along caudal peduncle beyond end of fin base, extremely fleshy basally, fleshiness failing on distal half of fin, which is quite membranous; margins of fins straight, more or less paral- lel to trunk axis. Anal origin at or a little in advance of dorsal origin. Dorsal and anal fins confluent with caudal peduncle flanges, which are very strongly developed. Caudal fin short, moderately fleshy at base, truncated to rounded. Pectoral fin short, membranous or slightly fleshy, rounded, inserted high laterally. Margins of fins serrate. Variation. Meristic: dorsal 10 (2), 11 (4), 12 (7), 13 (21), 14 (2); caudal 15 (6), 16 (25), 17 (5); anal 13 (4), 14 (5), 15 (19), 16 (4); pectoral 11 (1), 12 (14), 13 (17), 14 (4); branchiostegals 6 (12), 7 (24); vertebrae 55 (2), 56 (9), 57 (7), 58 (12), 59 (10), 60 (2); gill rakers 2-8 (5), 2-9 (3), 3-8 (8), 3-9 (14), .3-10 (6), 4-8 (2), 4-9 (3), 4-10 (1). Morphometric: see Table 5, p. 399. Coloration. Dark colored; in populations examined from peat bogs, a dark smoky gray to almost black; profuse fine vermic- ulations cover the dorsal and lateral trunk and the fin bases. The belly is paler, smokey gray to somewhat rufous. Size. An example from the Waiharara series measured 122 mm total length. Samples contained few examples more than 90 mm long. Population differences. Noticeable dif- ferences in meristics were found for the two large samples of N. diversus examined. The Waiharara sample (the more northern locality) was found to have generally fewer counted structures, especially vertebrae, anal fin rays, and gill rakers. The sample from the most southern locality, Mount Pirongia, included only four fish, but these appeared to be more similar to those of t
