Observations on fishes of the family Galaxiidae: Part 2.

In Part 1 of these Observations (Scott, 1936), devoted to a taxo- nomic survey of the family, with descriptions of new species, the hope was expressed that in succeeding parts it would be found possible to consider the Tasmanian Galaxiidae described prior to 1936. The present contribution contains some biometric observations on the widely distributed Galaxias (Galaxias) attenuatus (Jenyns), relating Chiefly to frequency distribution of standard length, including seasonal variations; rate of growth; variation of proportions with growth; growth-gradients; extra-aqueous viability. Non-metrical observations on this species are reserved for a subsequent communication.
