the regions on either side of this one, should be entirely wanting

The placental Mammalia are represented by about twenty 

 species, exclusive of the Cheiroptera, mainly of Asiatic types. Six- 

 teen of these are found on the island of Celebes, and comprise sev- 

 eral rodents (mice and squirrels), a wUd-hog, a deer (Cervus hip- 

 pelaphus), very closely related to, if not identical with, a Javan 

 species; a civet- cat, a spectre-lemur (Tarsius spectrum), and three 

 peculiar forms, unlike anything found either on the continent of 

 Asia or the Malayan islands. These are a black and almost tailless 

 baboon-like ape (Cynopithecus nigrescens), an antelopean buffalo 

 (Anoa depressicornis), and the babyroussa (Babirusa alfurus). 

 Several of these, or closely allied forms, are also found in the 

 Moluccas, and in the group of islands and islets which stretch 

 eastward from Lombok to Timor. We have here, in addition, one 

 of the commonest species of Malay monkey, the Macacus cynomol- 

 gus, a Paradoxurus, and a possible second species of deer, Cervus 

 Timoriensis. The implacental mammals of the connecting region 

 comprise only Cuscus and Belideus.
