The second genus in this small but natural family of 4 species is the
monotypic Calonmium from New Zealand, which, although gymnostomous,
and with a dimidiate calyptra, agrees so closely in habit and structure
of leaf with our Georgia, pellucida, that its place in this family ought to be
at once apparent, yet Lindberg appears to be the only author who has
noticed its true affinity; see his remarks in Act. Soc. scient. fenn. X,
p. 240 (1872).
