Mr. L. P. Capewell, as far as we can discover from available literature, was the first person to collect a fresh-water sponge in Australia. This sponge was collected in Lake Hindmarsh, Victoria. Dr. J. S. Bowerbank in 1863 described this sponge as a new species and illustrated it with a good drawing. The sponge being a new one was named for the finder and was called Spongilla capewelli; now that the nomenclature has changed somewhat, this species becomes known as (1) Ephydatia capewelli (Bowerbank). Mr. H. J. Carter, writing in 1881, improved the original description somewhat. Later writers have also mentioned this form, but have added very little to the splendid descriptive notes made by Bowerbank and Carter.
