A line drawn l)etween the outer angles of the body crosses the median longitudinal line twice the length of the snout from the tip of the snout, or varying to half the diameter of the eye less than this distance. The spiracle from its posterior edge to the posterior edge of the iris is equal to the length of the iris, or to the posterior edge of the eye-ball is contained 2 times in the eye-ball. Holding the outer lobe of the ventral straight back and measuring from the bottom of the notch in the i)osterior edge of the ventral to its tip the distance is equal to the interorbital width, or a little greater. Holding the edge of the anterior ventral lobe so that it is at a right angle with the posterior lobe a deep rounded notch is left in its posterior edge. The anterior half of the rostral ridges are fused to- gether. The nearest point on the edge of the disk from the anterior edge of the eye-ball is equal to the width of the inter-spiracle or a little less. The general outline of the anterior margin of the disk is deeply concave with a slightly convex median area.
