Coloration. Trunk a milky gray-brown, covered dorsally and laterally with fine, darker, greenish brown vermiculations, these extending well on to the fin bases. Belly paler, a milky brown. Size. An example from the Anama sample measured 146 mm total length. Amongst the few fish examined, a good proportion were 100-125 mm long. Population differences. Unfortunately, all the specimens examined were collected from the Hinds River System, in the same restricted area, so that no investigation of differences between populations was pos- sible. Habitat. N. burrowsius appears to be collected usually from small, muddy, or gravel-bed streams and creeks, often those draining swamps. Phillipps (1926c: 532) reported their ability to aestivate in small pockets of mud in the same manner as other Neochanna species are well known to do. Stokell (1949: 482) also reported specimens dug out of "damp earth and detritus at the bottom of a drain that had been dry for over a ; Life history. N. burrowsius collected from the Hinds River System in early August were approaching maturity. All those taken in November were spent. Thus N. burrowsius probably spawns in the spring. No females from the August sample were sufficiently mature to permit counts or measurements, but egg number appeared to be moderately high, laps comparable with that of G. macu- latus. There is no whitebait stage and no obvious juvenile-adult metamorphosis, and it is almost certain that N. burrow- sius spends all its life in fresh water. Distribution. N. burrotvsius is known only from the Canterbury District, South Island. It has been collected from the fol- lowin
