some pages after the place just quoted, in the same publication, when J dealt with the Cuddie Springs mandible.

24 Chapter 3: -f Megalania OWEN, 1860. a) Skull: The data regarding this subject contained in my Monograph (p. 449—455) may be completed, at present, only as far as the shape of teeth and the knowledge of the maxillary be concerned. In op. cit. the teeth of Megalania were dealt with on the base of Sir R. OWEN'S note regarding the type of Notiosaurus, consisting in a small fragment of the mandible's os dentale. In this specimen only the basal part of two teeth is preserved, so that the exact shape and structure of them could not be established. I supposed the teeth to be „pointed" and „curved backwards", though adding to these hypothetical data of mine an interrogation mark.

25 Mr. DE VIS' paper (1885) cited above — unkown to me when I was writing my Monograph — proves that the supposition just quoted fully covers the facts. Mr. DE VIS

26 describes the tooth he obtained from Clifton, Darling Downs, and determined by him as Notiosaurian, as follows: „The teeth in Monitor, compared with those in Hydrosaurus, are broad and thick; the tooth of the latter" — i. e. of IVCH tiosaurus — „is distinctly serrated on both edges, while in the Monitor tooth the fore-edge only is serrated, and that faintly. The outline of the tooth of the extinct lizard resembles that of Hydrosaurus, but it is proportionately thicker; its fore-edge is smooth and also like the Monitor tooth, it has the basal fluting extended higher on the inner side towards the crown than in Hydrosaurus. On the other hand, its shape and the almost entire want of the ridge descending upon the outer side of the tooth sufficiently differentiate it from a Monitor proper. We have, therefore, here additional evidence that the extinct lizard had greater affinity with the smaller than with the larger of those two living genera."

27 I do not find anything I could add to this description, offering plenty of evidence with respect to the morphology of Megalanian teeth, being, besides, completed by a drawing representing the Clifton tooth in natural 24 Op. cit. p. 454—455. 25 Op. cit. p. 449. 26 DE VIS, op. cit. p. 51—32. 27 Under „Hydrosaurus" Varanus giganteus GRAY is meant, whilsi under „Monitor" V. Gouldi GRAY is to be intended.
