size and accompanied by two natural size drawings of each a tooth of V. giganteus GRAY and V. punctatus GRAY.

28 With respect to the tooth described and figured by DE VIS I must yet observe that Mr. R. ETHERIDGE Jr. expresses, when recording it, some doubts with regard to the correctness of its identification in the above sense. He writes as follows: „I very much doubt if the tooth figured by Mr. de Vis as Notiosaurus dentatus™ is in any way related to OWEN'S fossil of the same name."

31 I must confess to be fully unaware of the causes of Mr. ETHERIDGE'S doubts, who does not give any explanation in view of supporting, somehow, his quoted personal impression. Mr. ETHERIDGE'S paper just mentioned

32 does not contain new data about the teeth of Megalania, and its author merely refers to a part of OWEN'S .,Odontography" (pt. II, p. 265) applicable to the one tooth base preserved in the Clifton Station maxillary described and figured by him. Now, as regards the maxillary, the consideration of the two photographs given by Mr. R. ETHERIDGE Jr. (op. cit. Pl. VIII, Figs. 1—2) afford the following details. Habit of Varanian type: very massive in structure, strongly widened in dorsoventral sense, most resembling, by this feature, the maxillary of V. niloticus L. It „is fractured in front at about the premaxillary suture, and as preserved measures six and a-half inches in length."

FEJÉRV., nunc —- ala superior oss. max., FEJÉRV., 1918) — i. e. the dorsal-crest-like part meeting the intranasal (= turbinai) — preserved only in its very basal portion. Margo lacrimalis oss. max.

(mihi) preserved in greatest part of its course apperently but trifling portions wanting of it at the ends of both its dorsal and ventral rami. Excavatio nasalis ossis maxillaris (FEJÉRV., 1918) — so far as discernible on figure — moderately impressed, rather shallow, and not presenting any acute delimitation ridge. Crista dentalis oss. max. intact, serrated, the spaces between the serrations presenting a broadly rounded, quasi lobi28 Figuring under the name of „Odatria punctata'*. 30 DE VIS, Proe. Roy. Soc.
