This is an imperfect snout in which is preserved the symphysis and the major part of the premaxillaries and maxillaries. In both pre- maxillaries 5 incisors are preserved and here the 5th is only slightly shorter than the anterior 4 incisors. But on the left side there is a stump of what appears to be a small 6th incisor. On the right side a stump of the canine is preserved, as also stumps of the 2nd and 4th postcanines and empty alveoli of the 1st and 3rd. On the left side the canine has dropped out and so has the 1st postcanine, but stumps of the 2nd and 3rd are preserved. The maxilla overlaps the premaxilla right up to the level of the anterior edge of SAtM>32. d. C SAM C. Fig. 1.—a, Scymnosaurus ferox. Tvpe. 632. (x \.)
