FAMILY 16. TUPAIID^E. (3 Genera, 10 species.) 



GENERAL DISTRIBUTION. 



The Tupaiidae are squirrel-like shrews, having bushy tails, 

 and often climbing up trees, but also feeding on the ground and 

 among low bushes. The typical Tupaia (7 species), are called 

 ground squirrels by the Malays. They are most abundant in 

 the Malay islands and Indo-Chinese countries, but one species 

 is found in the Khasja Mountains, and one in the Eastern Ghauts 

 near Madras. The small shorter-tailed Hylomys (2 species) is 

 found from Tenasserirn to Java and Borneo ; while the elegant 

 little Ptilocer&s (1 species) with its long pencilled tail, is confined 

 to Borneo ; (Plate VIII. vol. i. p. 337). The family is therefore 

 especially Malayan, with outlying species in northern and con-

Extinct Species. Oxygomphus, found in the Tertiary deposits 

 of Germany, is believed to belong to this family ; as is Omomys, 

 from the Pliocene of the United States.
