The definition of Apomys, a native rat of the Philippine Islands. American Museum novitates ; no. 2746

43 p. : ill. ; 26 cm.Includes bibliographical references (p. 41-43)."Apomys Mearns (1905) contains eight species native to the backbone of the islands in the Philippine archipelago. The genus was recognized for more than 40 years after it was described, then merged with Rattus, and later reinstated as distinct from Rattus. Throughout this period, the morphological boundaries of the group remained vague, the diagnosis nonexistent, and the contents nebulous. Apomys is defined here, the species in it are discussed, and the contrasts between it and Rattus are outlined"--P. [1]
