The New Ireland forest rat (Rattus sanila) is a large rodent in the family Muridae. It is endemic to New Ireland, in the Bismarck Archipelago, Papua New Guinea.
Ratus sanila is known only by the discovery of some 7 subfossil fragments of jaw dated to over 3000 years old. The molars of this particular species are broad and have a very complex structure of the cusp. The diastema is also longer than in other species of the genus Rattus suggesting a separate species which may be a relict of an archaic or ancestral dispersal of Rattus stock to New Guinea and Australia. This species probably still survives in some primary forest. [1]
Rattus is a genus of muroid rodents, all typically called rats. However, the term rat can also be applied to rodent species outside of this genus.
The Flores giant rat is a rodent of the family Muridae that occurs on the island of Flores in Indonesia. It has been recorded in Rutong Protection Forest. The species is found in primary, secondary and disturbed forest over a wide range of elevations. Head and body length is 41–45 cm (16–17.5 in) and tail length is 33–70 cm (13–27.5 in). These dimensions are about twice as large as those of a typical brown rat, which suggests about eight times the body mass.
The Old World rats and mice, part of the subfamily Murinae in the family Muridae, comprise at least 519 species. Members of this subfamily are called murines. In terms of species richness, this subfamily is larger than all mammal families except the Cricetidae and Muridae, and is larger than all mammal orders except the bats and the remainder of the rodents.
Mastomys is a genus of rodent in the family Muridae endemic to Africa. It contains eight species:
The Philippine forest rat is a species of rodent in the family Muridae. It is found only in the Philippines, and is located throughout the archipelago. The scientific name commemorates British colonial administrator and zoological collector Alfred Hart Everett. The Chanum Torres is widespread throughout its range and feeds on a diet of worms and insects. There are no major threats to the species, which has been found to be competitively superior to introduced Rattus species.

Baiyankamys is a genus of amphibious murid rodents. It was originally described, along with the species Baiyankamys shawmayeri by Hinton in 1943 after he found the remains of a single individual in south east of the Bismarck Mountain Range, north east New Guinea. Tate, in 1951 and, Laurie and Hill in 1954, confirmed the existence of both the species and genus.
