Sometimes there is a special row of large scales along the top of the back of the snake, i.e., the uppermost row, called the vertebral scales. The enlarged scales on the belly of the snake are usually called ventral scales, although several names are used in the (older) literature, including ventralia, gastrosteges (plural gastrostegi ...
