380 Zoological Society : — C. ridibundus, but cannot be confounded with that or any other species, the broad black mark in the centre of its first two primaries, together with its larger size, serving at once to distinguish it. It was brought from Tibet by Major W. E. Hay, F.Z.S. Notes on some New Lizards from South-Eastern Africa, WITH the Descriptions of several New Species. By Dr. J. E. Gray, F.R.S., etc. Dr. John Kirk has most kindly sent to the British Museum a series of Lizards, Snakes, Insects, and other animals collected during the Zambesi expedition, under H. M. Consul the Rev. Dr. Living-stone. As the series of Lizards contains some species which do not appear to have been previously inserted in the ' Systematic Cata-logue,' I forward an account of them to the Society. Gerrhosaurus robustus, Peters, Monatsb. 1854, p. 618. nab. Tette {Peters; Br. Kirk). Dr. Peters gives the word Caaiia as the name of this Lizard ; but. Dr. Kirk informs me, that word simply means " I do not know," which was probably what the native said when he asked him what they called it. Common near Tette. The native told Dr Kirk that it entered fowl-houses and killed the fowls, and that it bit very hard. This species agrees in general appearance with the Lizard figured in Dr. Andrew Smith's ' Illustrations of the Zoology of South Africa,' under the name of Gerrhosaurus Bibronii ; but the head of the Tette specimen is dark brown like the body, and is spotted with white ; while in Dr. Smith's species the head is figured as uniform red-brown. Teira ornata, n. s. Blackish brown above (in spirits), with three narrow continuous streaks from the occiput to the base of the tail ; head with small symmetrically curved white lines ; sides of the head and body with numerous erect, more or less sinuous, white cross bands ; chin and beneath white ; tail pale reddish brown ; ventral shields six-rowed ; the throat with a shght fold of a single series of rather larger flat scales ; under the ears, scales small, granular, smooth ; of the tail elongate, keeled. Hab. South-Eastern Africa {Br. Kirk). Lygodactylus, n. g. Toes free, all clawed, slender, and subcylindrical, with a series of small scales beneath at the base rather dilated ovate, and with two series of regular transverse plates, separated by a central groove be-neath, at the end ; the thumb (of the hind foot, at least) large. Head, body, and tail covered with uniform granular scales. Tail cyhndrical, tapering ; front of the vent granular. Labial shields large, similar in form, smaller behind, with a large shield in front of the chin. This genus agrees with Thecadactylus in the form of the plate
