Abstract

Terrestrial isopuds present problems in respiration because
of their change of habitat. With organs of respiration
which are homologous with the tbranchire of Asellus and
other aquatic isopods, they live on land and breathe air.
They are found in very varied situations; some require very
wet conditions, others can live in comparatively dry places.
In this communication I propose to describe the interesting
anatomical features of the respiratory organs of
certain species.
In the species treated of, and in the Oniscaddea generally,
five pairs of ahdominal app·endages take some part in
respiration. I propose to describe these appendages in the
female forms only. There are no differences in the essential
points of histology and physiology between the male and
female pleopods, and the fact that, in the male, reproductive
processes are associated with the 1st and 2nd p1eopods,
brings in an unnecessary complication.
