The standard work of licrpetology concerning the fimna of Barbary, upon 

 which all farther knowledge on the subject must necessarily be based.

This magnificent work, with its beautiful plates, is not only valuable to a 

 herpetologist, but especially for an amateur in herpetology, on account of its 

 instructive plates, explicit letterpress and biological notes.

Neither of the common Algerian Chelonia, Testudo ihera and Cleinmys leprosa, 

 extend into the real Sahara. The former Mr. Rothschild and I saw as far south 

 as Lambese, near Batna, where it is common, while the latter is also numerous near 

 Batna, and occurs in some of the ditches of the oasis of Biskra. 



1. Ptyodactylus lobatus oudrii Lat. 



Cf. Boulenger, "Kept, and Batr. Barbary," in Trans. Zool. Soc. London xiii. part v. pp. Ill, 112 

 (1891). 



Common in the Bordjs north of El-Golea and in houses at El-Golea itself. 

 Not very difficult to catch, though the tails are broken off very easily. Common 

 also near Biskra. 



It appears from Mr. Boulenger's notes that " var. oudrii " is the western sub- 

 species of P. lobatus lobatus, though connected with the latter by a complete 

 intergradation, but generally smaller.
