Gunther's type is recorded as being in the British Museum. Type locality: Westland. Localities! (South Island) Greymouth. (North Island) Palmerston North, Rongareu, Wairarapa. Habits: This fish is normally free-living, but during droughts it is frequently found alive in the mud of streams and swamps from which the water has been absent for months. Male specimens taken
in October had the milt almost fully developed and appeared to be within a week or two of spawning.
