Bartels's rat

Bartels's rat (Sundamys maxi) is a large rodent in the family Muridae found only in West Java, Indonesia, including Gunung Gede Pangrango National Park, at elevations of about 900 to 1350 metres. Adults measure roughly 218 to 270 millimetres from head to body, with a tail of 258 to 309 millimetres and a weight of 521 to 643 grams, similar in size to the mountain giant rat. The fur is dark brown above and only slightly paler below. It is probably nocturnal and terrestrial and likely lives in primary forest. The species is known only from specimens collected by Max Bartels Jr. between 1932 and 1935, little forest remains in its type locality, and the IUCN lists it as threatened.
