description
Descriptive notes. Head-body 160 - 208 mm, tail 146 - 180 mm, hindfoot 39 - 42 mm. No specific data are available for body weight. The Tawitawi Forest Rat is medium-sized, with soft, short, thin, and sleek pelage; translucent, soft, and flexible spines; and black guard hairs throughout. Dorsum is rich dark brown, speckled buff and slightly lighter on sides due to suffusion of gray. Hairs are dark brown or black, although some have buff banding around tips that cause speckling. Venteris grayish, tinged with silver and buff, and hairs have gray bases and translucent or buff tips. Rusty patch occurs on chest, chest to chin, or chest and throat. Feet are dark brown dorsally and ventrally on hindfeet and light brown ventrally on forefoot. Ears are small and similar in color to dorsum. Tail ¢. 87 % of head-body length and unicolored dark brown. Skull has generally large, wide, deep, and chunky cranium. There are four pairs of mammae: one post-axillary, one abdominal, and two inguinally.
