Peringueyi's adder is a snake closely confined to the sand areas of the coastal Namib Desert, where it attains a length of about 1 foot. In certain restricted localities it is by no means uncommon, although it is a snake poorly represented in most museum collections. There can be little doubt that the snake is ordinarily nocturnal, although it may be found abroad on the overcast misty days so characteristic of the coastal Namib at certain times of the year. Normally specimens can most readily be obtained by digging at the bases of small bushes where the snakes lie concealed in the sand of the shaded areas. One specimen was collected as it lay among the branches of a small shrub, showing that these adders are capable of climbing.
