While largely herbivorous, Five belt transects of 500 x 6 m were laid at Kalakhedi it occasionally feeds on insects during the summer (Dutta where lizard distribution was recorded and active burrows and Jhala 2007). It is solitary; adult lizards excavate burrows were counted by two observers during June 2013. Since, the generally 6–8 cm wide and 2 m long.

PHOTOGRAPHIC RECORD AND FIELD OBSERVATIONS OF A BROWN-SPOTTED PIT VIPER BHATTACHARJEE , K.1 140/1 Tangra Road, Block-D, Flat 4, Kolkata 700 015, West Bengal, India. Email: [email protected] doi: 10.17087/jbnhs/2014/v111i2/72242 On November 05, 2013, during a field survey of vertebrates of Namdapha National Park (27° 29′ 27.8′′ N; 96° 22′ 32.2′′ E; 516 m above msl), Changlang district, Arunachal Pradesh, India, a team of biologists came across what appeared to be a Brown-spotted Pit Viper approaching a small rodent on the forest floor. They observed the snake for nearly 60 minutes. During this time, the snake initially hid itself beneath foliage and left the prey for a while. It approached the prey, which was already dead presumably due to an initial bite, finally after 7–10 minutes and began swallowing the prey. Observations were made and photographic records Fig. 1: The viper approaching its prey obtained (Figs 1–3). An imaginary line of the body from head to tail (depending on the position of the snake) was measured using a string, which was later measured using a scale to obtain the average length of the snake (Fitch 1987; Jesus et al. 2008). The taxonomic identification of the pit viper is unconfirmed as no scalation data was recorded. Visually, the species appeared similar to Protobothrops mucrosquamatus. The type locality of P. mucrosquamatus is Naga Hills, which has similar topography to the present recorded location of this viper (Boulenger 1890, 1896; Günther 1864; Levinton et al. 2003).
