Ptyas carinatus

The black-netted snake is disc-shaped, with a diameter of about 16cm. The surface is dark brown or green-black, densely covered with diamond-shaped scales. The dorsal scales are in pairs, and the 2-4 rows of scales in the middle of the back are strongly ridged, forming two black nets running vertically across the body. The head is in the middle, flat and round, and most of the eyes are large and not sunken but shiny; there is one cheek scale, one smaller scale under the eyes, and two scales behind the eyes. The spine is high and looks like a roof ridge. When the abdomen is cut open, the edges curl inward, the spine muscles are thick, yellow-white and light brown, and neatly arranged ribs can be seen. The tail gradually becomes thinner and longer. When skinned, only the skin of the head and tail is left, and the middle section is smoother. It has a fishy smell and a light taste.

Mainly distributed in Myanmar, Thailand, Malay Peninsula, Indonesia (Sumatra, Java, Borneo), China.
In China, it is only distributed in Yunnan.
