Both specimens were in the pet trade and are from unknown localities. Diagnostic characters are obvious. A. <i>Tupinambis teguixin</i> lacks granular scales separating the supraoculars from the ciliaries, it has a single loreal scale, and the head is slightly compressed (dorsoventrally). B. <i>Salvator merianae</i> has granular scales between the supraocualars and the cillaries, a divided loreal, and a deep head. Also note the tall and horizontally divided lower labials.
