Division IV. PALUDICELLINA, nov.
The zooecia are arranged in a regular cruciform manner and arise either directly one from another or with the intervention of tubular processes.
If the polypide has a gizzard it does not bear internal chitinous projections. Most of the species are confined to fresh water, but a few are found in brackish water or even in the sea.
Although all true freshwater Ctenostomes belong to the fourth of these divisions, species of a genus (_Bowerbankia_) included in the third are so frequently found in brackish water and in a.s.sociation with one belonging to the fourth, and are so easily confounded with the latter, that I think it necessary to include a brief description of the said genus and of the form that represents it in ponds of brackish water in India.
