I may here observe that the Lizard which I described as Homo- 
dactylus turneri (Proc. Zool. Soc. 1864, p. 59, t. 9. f. 2) is the 
same as Pachydactylus (Tarentola) bibroni of Sir A. Smith (Illus- 
trations of the Zoology of South Africa, Reptiles, t. 50. f. 1). I 
cannot conceive how I overlooked this plate when describing the 
animal. Sir Andrew Smith observes it is not a typical Tarentola ; 
this explains why I did not look in that genus for the species. It 
must now be called Homodactylus bibronit. 
The Lygodactylus strigatus of the same paper (Proc. Zool. Soc. 
1864, p. 59) is the Hemidactylus capensis of Sir A. Smith, de- 
scribed and figured in the same work. 
Dr. Peters, who pointed out these synonyma from the examina- 
tion of Sir Andrew Smith’s typical specimens, which have been sent 
to the British Museum since the species were described, informs me 
that he has “found the latter animal in ‘a fossil state’ in copal 
received from the coast of Zanzibar, showing that it has a very ex- 
tensive geographical range.” 
The figures of both the Lizards given in Plate XXXVIII. are 
double the natural size.
