The exterior surfaceof the hone is smooth and polished, but impressed by very fine, lon-gitudinal linear markings, and perforated by nervous or vascularforamina along the alveolar wall: it is traversed near the lower mar-gin by a line answering to the suture dividing the dentary from theangular piece in the jaw of the Varanus. The ramus is compressed(fig. 3), scarcely 2 lines across at its thickest part, but it has beenslightly crushed. The enamelled crowns of the teeth are moderately long, slender,compressed, pointed, slightly recurved, and with a well-marked serratedmargin both before and behind (fig. 4, m
