lvi INTRODUCTION. 
Strauch 1 , in his account of the Reptilian fauna of Algeria, recorded Seps chalcides, 
Bonap. = Chalcides tridactylus, Laur., as an Egyptian lizard, but the evidence as to the 
existence of this species in Egypt is as yet inconclusive. 
In 1863, Jan 2 indicated a snake as Coronella austriaca, Laur., var. cegyptiaca, thus 
implying that it came from Egypt. This is, however, so extremely improbable that 
it must be attributed to an error of locality. 
In the same year, Peters 3 recorded the presence of Tropidonotus tessellatus (Laur.) 
in Egypt. 
Dr. Steindachner, in 1807 4 , mentioned the occurrence of a frog in Kordofan, which 
he named Pyocephalus cordofanus=Rana cordofana (Steindacb.). 
The late Professor Cope described, in 1868 5 , a new chameleon from Nubia, which he 
named C. basiliscus. An example of this species from Egypt had been presented to 
the British Museum by James Burton between 1824-30, but Dr. Gray had regarded it 
as C. vulgaris. 
Peters, in 1869 6 , recognized that the Agamoid lizard from Dongola, which he had 
at first identified Avith Agama savignyi, D. & B., was a new species, and named it 
A. hartmanni. In the same year, he described a small gecko from Sennaar, under 
the name Gymnodactylus steudneri, Peters, = Tropiocolotes steudneri (Peters). 
The viper V. lebetina was stated by Strauch in 1869 7 to be represented in the Berlin 
Museum by an Egyptian specimen ; but by the courtesy of Dr. Tornier I am enabled 
to state that no such example is present at Berlin, where there is, however, a specimen 
labelled from North Africa. 
Gray 8 , in his short account of the few reptiles collected on Petherick's journey, 
described a chameleon, which he named C. Icevigatus, Gray, = 6'. senegalensis, Daud., 
from 805 kilom. to the south of Khartum. 
Strauch 9 , in his monograph of the snakes of Russia, mentions Coronella austriaca, 
Laur., as an Egyptian snake on the erroneous statement made by Jan ; and also Coluber 
quadrilineatus, Pallas=C. situla, Linn., on the authority of the ' List of Animals living 
in the Zoological Gardens, London ' 10 . His retention of Vipera ammodytes (Linn.) as 
a member of the fauna of Egypt rests solely on a statement by Pliny quoted by Solinus, 
who lived about a.d. 238.
