Hydromys oriens Troughton, 1937a View in CoL

Rec. Aust. Mus. 20 (2): 127. (27 August 1937).

Common name. Water Rat.

Current name. Hydromys chrysogaster É. Geoffroy, 1804 ; following Musser & Carleton (2005). Taxonomic status unresolved: extensive morphological variation within H. chrysogaster is in need of review ( Flannery 1995b; Musser & Carleton, 2005).

Holotype. M.4683 by original designation. Adult male, [No. 43], skull ( Fig. 37 View Figure 37 ), study skin, collected and presented in 1929 by Mr C. T. McNamara, registered in September 1929.

Condition. Cranium and left dentary complete; right dentary missing coronoid process. Study skin in good condition, with no obvious external genitals.

Type locality. Mount Lamington district, Northern Province, Papua New Guinea.

Comments. Evidently based on one specimen, for which Troughton provides measurements taken from a body in alcohol. There are no other specimens of Hydromys collected by McNamara from Papua New Guinea in the AM Collection. Flannery (1995b) lists 18 names from the Australo-Papuan region under “ chrysogaster ” and states that the species is “profoundly in need of revision” .
