he Littoral zone, the Naticae, mostly well-known
species, were taken in sandy localities on the north-east coast, and the
Neritae in the same province, mostly on rocks or reefs. Littorina
pyramidalis and mauritiana are inhabitants of the rocky headlands of
Broken Bay; other forms were collected at Port Curtis and at Port
Dalrymple. At the last-named locality, Turbo undulatus, a new Risella,
Monodonta constricta and buccata, and Trochus reticularis were taken on
reefs. Littoral species of the same genera occurred on the north-east
coast. A New Rissoa was found under stones at Night Island. Turbo
squamosus and Trochus lentiginosus are inhabitants of the shore at Port
Essington. In Broken Bay species of Bankivia and Scalaria were collected,
cast dead on the shore.

The Acephala found living in the Littoral zone of the south-east
Australian province were Cleidotherus chamoides, under rocks at low-water
in Port Jackson; Mytilus erosus on the mud of zostera flats at Port
Dalrymple, several species of Venus, Tapes, Cytherea in similar
localities; Arca globata in the same habitat at Brisbane; Arca fuscata in
reefs at Port Dalrymple; a new Tellina on mud at Port Phillip; another
with Donax epidermia in sand at Broken Bay, and Clavagella australis on
rocks at low-water, Port Jackson. Species of Pectunculus, Nucula,
Pandora, Anatinella, Venus, Tellina (decussata and deltoidalis) and
Mesodesma are thrown dead on the shores.

In the north and north-east Australian province the living littoral
Acephala are Solens of which two new species were taken at Port
Essington, Anomia australis, Anatina olerina, and another, new, in the
same locality; species of Mytilus, Meleagrina and Pinna, Ostrea and
Pecten (pyxidatus) Lima fragilis and squamosa, Hippopus and Tridacna, the
former detached on coral reefs, the latter embedded in the coral, Corbis
fimbriatus in sand among coral reefs; species of Venus, Cytherea, Circe,
and Tapes in mud, Artemis sculpta at Port Essington on sand, Lucinae on
sand or reefs, Crassatella on mudflats at Port Curtis, where Cypricardia
vellicata occupies the fissures of rocks with Carditae; several species
of Cardium in mud or sand, including C. fragum, C. subrugosum, and C.
unedo; Sanguinolaria rugosa at Dunk Island; species of Mesodesma in sand,
and Mactrae and Tellinae in mud; a new Psammobia at Port Essington as
also a new Pholas that bores into coral. Other species, members of the
same genera, are cast on shore d
