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 Lizarps FROM SoutTH-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. 
Hab. Tette (Peters; Dr. Kirk). 
Dr. Peters gives the word Caazia 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 slight 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 (Dr. Kirk). 
LYGOPACTYLUS, 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 
cylindrical, 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
