Note 388 — Chapter XII · DISTRIBUTION OF MARINE MOLLUSCA—DEEP-SEA MOLLUSCA AND THEIR CHARACTERISTICS
Reading edition
According to Tate (Trans. Roy. Soc. S. Austr. 1887–88, p. 70), ‘Australian’ species predominate at Freemantle (32°), but Tenison-Woods (J. Roy. Soc. N. S. Wales, xxii. p. 106) holds that the tropical fauna extends as far south as Cape Leeuwin (34°), and that the Australian forms are not predominant until the extreme south. Tenison-Woods regards Cape Byron (31°) as the limit of the tropical fauna on the east coast, while some characteristic tropical genera reach Port Jackson, and a few (e.g. Cypraea annulus) Tasmania.
