Add new subgenera and change the for
nation Of varieties. For great trans
formation in the fifth class Of verte-
brate animals has resulted from the dig
ging Of the Chicago drainage canal and
the commingling of the lakes waters
with those of the rivers. The digging
OF the channel across the great divide
that once separated Lake Michigan
from the Mississippi Valley has let
the lake fish Into the Des PLANES, the
Illinois and the Mississippi rivers. The
seeming unnatural commingling of wa
tiers has produced fishes that seem I'M
natural-that is, when compared to our
present standards. New forms. new
varieties, new types have appeared,
differing In color, habits and general
description from any other known to
the American pisciculturist. Coexist-
ent with the appearance Of the new
kinds of fishes there Is noted most
remarkable increase generally In the
number Of the finny Inhabitants of the
