Identification. This medium-sized snake was iden- tified as a kukri snake by its stocky robust body and

characteristic “kukri snake” facemask with dark brown V-shaped markings. It was assigned to O. cyclurus due to 19 midbody scale rows, one preocular, two postoculars, yellowish-brown body with darker brown markings in rows which combine to form two dorsal stripes, and pink venter with white on the outer margins of the ventrals ( Das 2010; David et al. 2011). Our two examined specimens had seven supralabials ( III and IV contacting orbit), 177/184 ventrals, and 43/61 subcaudals, which places them at the limits of published descriptions (eight or sometimes seven supralabials with IV and V contacting the orbit, 161–185 ventrals, and 36–58 subcaudals) ( Das 2010; David et al. 2011).

Taxonomic notes. The presence of this species in LNP was published as the first record from Sylhet Division (Rahman 2012c).

Habitat. We found O. cyclurus only in degraded forest in LNP.
