ermide tenui pallide fusco-viridi obtecta, ad apicem
purpurascente; anfractibus convexis, lineolis transversis et
longitudinalibus elevatis decussatis, anfractu ultimo ad basin sulcis
impressis spiralibus instructo; apertura ovata, antice subeffusa; labio
vix reflexo.

Long. 1 inch, lat. 8 lines.

Habitat. King's Ponds, Arnhem's Land (Coll. Angas).

This is a neat, finely-decussated, concolorous species, with the upper
whorls nodulous from erosion, as in Vivipara praerosa, Gerst. It is named
after Mr. Stephen King, one of the gentlemen who accompanied the
expedition.

3. Melania (Melasma) onca, Adams & Angas.

M. testa fusiformi-turrita; spira elata, conica; epidermide pallide
olivaceo induta, rufo-fusca, pulcherrime maculata, maculis saepe in
lineis undulatis longitudinalibus dispositis; anfractibus planis,
longitudinaliter plicatis, plicis aequalibus regularibus subdistantibus,
ad suturas nodulosis; apertura oblongo-ovata, antice effusa; labio
subincrassato; labro simplici, acuto.

Long. 1 inch, lat. 4 lines.

Habitat. Tributary of Adelaide River, Arnhem's Land (Coll. Angas).

A species remarkable both for the elegance of its form and the beauty of
its painting. The whorls are plicate, with a necklace-like series of
nodules at the sutures; and the shell is covered with dark red-brown
spots, suggestive of its specific name.

4. Amphipeplea vinosa, Adams & Angas.

A. testa ovata; spira mediocri, tenui, semipellucida, vinosa; anfractu
ultimo magno, ventricoso, postice ad suturas gibboso; apertura ovata;
labio callo tenui mediocri obtecto, columella spiraliter tortuosa; labro
convexo, margine acuto.

Long. 9 lines, lat. 5 lines.

Habitat. Tributary of Adelaide River, Arnhem's Land (Coll. Angas).

This species may readily be distinguished on account of its peculiar
vinous colour. The whorls are posteriorly gibbose or tumid at the
sutures, and the callus is less spreading than in others of the genus.

5. Amphipeplea phillipsi, Adams & Angas.

A. testa ovata; spira elata, acuta, tenui, cornea; anfractu ultimo magno,
non ventricoso, transversim creberrime striato; apertura oblongo-ovali;
labio callo tenui expanso obtecto; labro simplici, acuto.

Long. 9 lines, lat. 4 lines.

Habitat. Arnhem's Land (Coll. Angas).

A neat, horn-coloured, finely transversely striated species, with an
acute elevated spire. We have named it after Mr. T. Phillips, who has
assiduously collected many new Australian shells.
