Rhinotyphlops schinzi, commonly known as Schinz's beaked blind snake, is a species of snake in the Typhlopidae family. It is endemic to southern Africa.[2][3]

Etymology

The specific name, schinzi, is in honor of "Herr Dr. Hans Schinz", who collected the first specimens in 1884 & 1885 in the Kalahari Desert. He should not be confused with Swiss naturalist Heinrich Rudolf Schinz (1777-1861).

Geographic range

It is found from Namibia and neighboring Botswana south to Calvinia and Kenhardt in Northern Cape, South Africa.[4]

Adults may attain a total length of 28 cm (11 inches).

Scales arranged in 22-26 rows. More than 400 dorsal scales in the vertebral series.[5]

Snout strongly hooked, with nostrils below the sharp cutting edge. Rostral large, but not extending as far as the eyes. Four upper labials. Nasal semidivided, the cleft proceeding from the first upper labial. Preocular present, narrower than the nasal or the ocular, in contact with the third upper labial. Eyes distinct. Upper head scales large than the body scales. Diameter of body 45 times in the total length. Tail as long as broad, ending in a spine.[6]
