Madras Treeshrew ("Anathana ellioti"), also known as the Indian Treeshrew is a species oftreeshrew in themonotypic genus "Anathana" found in the hill forests of central and southernIndia . The genus name is derived from the Tamil name of "Moongil Anathaan" or bamboo squirrel and the species name is after Sir Walter Elliot of the Indian Civil Services inMadras .This treeshrew is 16.0 to 18.5 cm long with a tail of 16.5 to 19.5 cm. Its dental formula is I 2/3 C 1/1 P 3/3 M 3/3. The dentition is suited for an omnivorous diet.

The Madras Treeshrew is found on the Indian subcontinent south of the
Ganges River . Three subspecies have been described — "A. e. ellioti" of theEastern Ghats , Biligirirangan and the Shevaroy Hills and other hills of Southern India, "A. e. pallida" from Central India primarily in Madhya Pradesh and Raipur, and "A. e. wroughtoni" from the Satpura Range and the Dangs near Bombay. Little is known about the status of these populations. The nominate race (Type locality: Eastern Ghats, Madras. British Museum 50.1.21.5) has the tail coloured like the back, the ground colour above being reddish brown while the feed and hind legs are buff or ochraceous. The other two races have the tail coloured differently from the back. The race "pallida" (Type locality: Manbhum, Bengal collected byRobert Charles Beavan British Museum 66.12.28.2) has the colour of body above reddish brown and the feet and hind legs grizzled buffy. Race "wroughtoni" (Type locality: Mandvi, Surat; Collected byR. C. Wroughton British Museum 96.11.7.1) has the colour of body above dull grizzled brownish and the feet and hind legs grizzled greyish. [cite journal|author=Wroughton, R. C.|year=1918|title=Summary of the Indian Mammal Survey. Part 2|journal=Journal Bombay Nat. Hist. Soc.|volume=26|pages=28–29] Some later workers lump all the three races.

[cite web | author = Bora, S. | year = 2002 | title = Anathana ellioti | work = [http://animaldiversity.ummz.umich.edu Animal Diversity Web] | url = http://animaldiversity.ummz.umich.edu/site/accounts/information/Anathana_ellioti.html | accessdate = 2006-10-16] It is easily separated from the squirrels in the field by the shape and color of the tail and the upward curve in which it is held when walking about.
They have a behaviour of climbing up low slanting trunks and sliding down headfirst. [Chorazyna, H., G. Kurup. 1975. Observations on the Ecology and Behaviour of "Anathana ellioti" in the Wild. Contemporary Primatology: 5th International Congress of Primatology: 342-344.] This may be associated with scent marking as many of the Scandentia have scent glands on their throat.
