Pseudochirus dahlii Collett, 1895

Zool. Anz. 18: 464, table 1. (2 December 1895).

Common name. Rock Ring-tailed Possum.

Current name. Petropseudes dahlii ( Collett, 1895) , following Jackson & Groves (2015).

Syntype. M.1247, by subsequent determination, as specimen “C” of the original series. Male, skin mount with extracted skull, “Arnheim Land, N.A.”, received in exchange from Robert Collett, register indicates “gallery mount” and “broken skull”, registered in December 1897. Old cardboard tag is labelled “1213 Phalanigista Mary River 14.5.95”. The skull was dissociated from the skin mount at the AM and re-registered as M. 13593 in August 1985. The cranium and dentaries both have “1213” inscribed in ink. The skull also has “C” inscribed in ink.

Condition. Incomplete cranium, missing left half of braincase and part of left zygomatic arch. Skin mount: faded, bald patch on the anterior surface of the hind left limb, bald patch on the dorsal surface of the head, bald patch on the posterior surface of the hind right limb.

Type locality. Mary River , northern Australia (= Northern Territory), given as 13°30'S 131°30'E by Collett (1895) GoogleMaps .

Comments. Type series stated in the original description to be one male, five adult females and one juvenile female. Skull measurements are given for six, designated as specimens A to F, but without registration or field numbers. Collett states that the specimens were collected from the Mary River in May 1895 by Knut Dahl. The AM syntype is specimen C, the only male syntype according to the original description, but Wigg & Bachmann (2013) list the syntype series as two males and five females. The other six syntypes are in the BMNH, MV, NHMO and RMNH (Wiig & Bachmann, 2013) .
