an analogous term; as, the Latin "pater" is the analogue of the English

different organ in another species or group, or even in the same group;
as, the gill of a fish is the analogue of a lung in a quadruped,
although the two are not of like structural relations. - A species in one genus or group having its characters
parallel, one by one, with those of another group. - A species or genus in one country closely related to a
