Back blackish; tips of the hairs rather browner; beneath rather paler on the sides of the abdomen; ears small; tragus oval lanceolate, rather crescent-shaped; wings, with sixteen or eighteen oblique cross lines of hairs under each fore-arm, and scattered hairs on the sides of the body; fore-arm, bone, 1 5-12; shin bone, 15-24.  Var. rather larger fore-arm bone, 1 7-12; shin bone, 17-24.

This species, Mr. Gould notes, flies quick and low over water.

Number 7.  Molossus australis.  See Gray, Magazine of Zoology and Botany volume 2 501.

Number 15.  Dasyurus viverrinus.

Mr. Gould has observed that the black and yellowish varieties are sometimes found together in the same litter.  There is an intermediate variety, blackish, with olive tips to the hairs.  Dr. Shaw’s specific name should be retained.

Number 18.  Phascogale affinis, Gray.

Above brown, grizelled with yellowish-brown tips to the hairs; beneath grey brown; under fur lead colour; tail short.  Male darker; length of body and head 6 1/2; tail 4 1/2.  Female, length of the body and head 4 1/2; tail 2 3/4 inches.  Inhabits Tasman’s Peninsula, Mr. Gould.

This may be the same as P. minima of Geoffroy, but the tail is longer for its size.

Inhabits Western Australia, banks of the Canning River, April 1839, Mr. Gould.

More specimens and further observations may prove these to be only local varieties of one species; but the specimens we have from the same localities are similar in character, which is not the case with the different specimens of Hepoona.
