also the Palaearctic region. Vandeleuria, Chiropodomys, Batomys, Carpomys are Oriental, the last two being confined to the Philippines.
Another peculiar Philippine genus is Phlaeomys, of large size, and allied to it is Crateromys, originally confounded with it. Batomys granti is also confined to Luzon. Its molars are three, like those of the also restricted and Philippine Carpomys melanurus, which is an arboreal form. There is a second species, C. phaeurus.
Phlaeomys is placed, however, by Mr. Thomas in a distinct sub-family of its own, Phlaeomyinae, and is removed from the Murinae.
Hapalomys, with but one species, is Burmese. Pithecochirus is Javanese and Sumatran. Conilurus (also known as Hapalotis) is a genus containing species which are termed Jerboa Rats, on account of their mode of progression. They are desert and Australian forms. There are sixteen species.

Mastacomys, with one species, is limited to Tasmania. Uromys, with some eight species, is from Queensland, and inhabits also the Aru Islands and the Solomon Islands. The Celebesian Echiothrix, or Craurothrix as it should apparently properly be called, is another genus containing but a single species. Golunda is both Oriental and Ethiopian, one species occurring in each region. The beautiful little striped Barbary Mice, Arviacanthis (or Isomys), are African, north as well as tropical.
The genus Saccostomus resembles the Hamsters in the presence of cheek pouches. Its teeth, however, are Murine. It agrees with Steatomys in the comparatively short tail. The caecum is rather long.
