We found the following shells in the river, viz.; two species of Melania, a Paludina, the lanceolate Limnaea, a cone-shaped Physa ( ?), a Cyclas with longitudinal ribs, and the Unio before described.

Murphy shot an Ostioglossum, a Malacopterygious fish, about three feet long, with very large scales, each scale having a pink spot.

We afterwards found this fish in the waters flowing into the Gulf of Carpentaria; both on its eastern and western sides: and, according to the natives of Port Essington, to whom I showed the dried specimen, it is also found in the permanent water-holes of the Cobourg peninsula.
