The head is flat-tened, and has the shape of an acute triangle, the summit of whichwould be rounded. The snout, therefore, is rather elongated, withthe end conical. The plates which cover its upper surface aresmooth, and faithfully represented in fig. 3. The scales of theback constitute twelve or thirteen rows, each of which is providedwith a medial carina, or ridge, extending over the tail.
