An endemic Non venomous snake occurs in all parts of the island up to about 2000 m a.s.l. Rather common in urban and sub urban areas. It is found under flower pots, piles of stones, loose soil, cracks and crevices of walls and parapets in houses, stacked bricks and piles of woods. Flowery Wolf Snake is a nocturnal terrestrial snake and it feeds on geckos, other snakes, rodents, insects, etc. It is very aggressive snake especially at night and savagely bite when handling. When cornered it hides its head underneath the coil of its body and sometimes empty its bowels with a smell similar to rotten dead mice. Hence its Sinhalese name කුණු මී කරවලා. It is an oviparous snake and lays 8 to 10 eggs at one time. Flowery Wolf Snakes often enter human habitations and are killed on sight as many believes it as a venomous snake. Some authors considered Lycodon osmanhilli as a color variety of Lycodon aulicus.

දේවකගේ තැලි කටුස්සා [Devakage Theli Katussaa]/Devaka's Fan-throated Lizard (Sitana devakai)
Fan throated Lizard inhabiting dry coastal areas of the North, Northwestern and Southeastern part of the country was formerly considered as a single species Sitana ponticeriana which is also recorded from the India. However with the recent taxonomic changes now it is considered that Sri Lanka is home to two distinct endemic species, one occurs in the Southeastern coastal areas (Sitana bahiri) and other in the Northern and Northwestern part of the island (Sitana devakai).
Devaka's Fan-throated Lizard is an endemic lizard confine to the dry coastal areas of the north and north western part of the island. However sometime it is recorded even 10-60 km from the nearest beach. It is active during the day time. Territorial behaviors of Sitana devakai are similar to its Southeastern congener Sitana bahiri.

Lowland Hump-nosed Pit Viper/පහතරට මූකලන් තෙලිස්සා[Pahatharata Mukalantelissa] (Hypnale zara)
An endemic snake restricted to the lowland rain forests of the south-western wet zone up to foot hills of the central highlands. It is a nocturnal snake and during the day time stay hidden under decaying logs and leaf litter on the forest floor. Maduwage K. et al. recorded of a rare occasion of observing this snake on a shrub up to about 60cm above the forest floor. Furthermore according to them Lowland Hump-nosed Pit Viper is absent in anthropogenic habitats. Above specimen was photographed on a banana shrub - considerable height above the ground- But habitat can't be considered as a primary forest though entirely not a home garden ( 6°22'24.18"N, 80°27'8.22"E). Location -though sort of anthopogenic habitat- is very close to the Gin river as well as Sinharaja forest.
