58 DR. J. E. GRAY ON AFRICAN LIZARDS, [Feb. 9, 
I received the specimen above-described from Mr. Gould. There 
is in the British Museum an imperfect skin of the same species, 
which was presented by Capt. Speke as coming from Unyamuezi. 
Capt. Speke’s specimen is not so brightly coloured, and the vertebral 
streak is not so broad and distinct. 
AULACODUS SWINDERNIANUS. 
Hab. The delta of the Zambesi, on the Sand-Islands. 
The flesh is much praised ; said to be very similar to the Cavies of 
South America (Dr. Kirk). ; 
Dr. Kirk has sent to the Museum two fcetal specimens of this 
animal with their membranes.

(Plate IX.) 
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 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, 0. 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
