Also several observed around this locality (loose sand substrate) in 2013 and 2015, and the Kyzylkum desert within Bukhara Province generally (but most not identified to species, i.e. some in more earthy consolidated substrates at higher elevation perhaps attributable to E. tataricus?).

Eryx johnii is a nonvenomous boa species endemic to Iran, Pakistan, and India. The type locality given is "Tranquebar" (Tanjore, Trichy district, southeastern Madras, India). The common name is red or brown sand boa. The head is wedge-shaped with very small eyes and narrow nostrils. The body is cylindrical in shape with small polished dorsal scales. The tail, which is blunt, rounded, and not distinct from the body, appears truncated. Coloration varies from reddish-brown to dull yellow-tan. These snakes are rather timid and shy, and bites have never been reported. (Near Vaigai Mens Hostel, Bharathidasan University)
