In the North-east Australian province, a different set of shells was dredged in similar depths, such as a Sigaretus, possibly new, Fissurella calyculata, Mitra obeliscus, a Turritella, a Murex, Columbella versicolor, and a new species off Cape York, Ranella pulchella, new, several Nassae, Phos senticosa and blainvillei, and sculptilis, in 3 and 5 fathoms, off Cape York; Strombus campbelli, in mud off Cape Upstart; Cerithium obeliscus, and a new species of the genus Obeliscus.

In the south-east Australian province the principal Gasteropoda procured were Bulla brevis, at Port Jackson, in 6 fathoms; Cyprea oryza, at Port Phillip, in 5 fathoms; Calyptraea connata, in 6 fathoms, Port Jackson, with Nassa suturalis, and another, a new Terebra, Monotigma casta, Mitra sordida, a Marginella, a Columbella, and Struthiolaria oblita.

In like manner, it is the presence of such genera as Pyrula, Columbella, Terebra, Cassidaria, Pholadomya, Lingula, Discina, and others which give a southern aspect to the Coralline Crag shells.
