Ptyas korros (Schlegel, 1837)

Material examined. BANGLADESH • 1 adult; Sylhet Division, Moulvibazar District, Kamalganj Upazila , Ful- bari tea estate bordering LNP; 24°19.53′N, 091°49.03′E; 15 Jun. 2011; photo voucher ZRC ( IMG) 3.370 .

Identification. Ptyas korros is a large, brownish rat snake with black edging on the scales of the hind body. It is differentiated from P. mucosa by the lack of black lines between the subcaudals, the lack of dark bands on the posterior portion of the body, and a dark ring encircling the pupil ( Whitaker and Captain 2008).

Habitat. This rat snake was seen regularly by us in all habitats in LNP.

Remarks. On 28 June 2015, JH observed a Paguma larvata (Hamilton-Smith, 1827) at a height of ~ 7 m in a tree feeding on a ~ 1.5 m long P. korros . Ptyas korros was never recorded in the roadkill survey. It may be more wary of roads or may cross them quickly, but it is possible that humans or scavengers, such as jackals and civets, remove these large snakes from the road more frequently

than small snakes.
