AND BATfiACHIANS OF BAEBAEY. 101 



Enumerates only 12 species, all of which were already on record. Uromastix spinipes, 

 Daud., stands for U. acanthinurus, Bell, and Zootoca deserti, sp. n., for Acanthodactylus 

 pardalis, Licht. 



The list of " Reptiles of the Sahara " (53 species), which forms Appendix VI. to 



11. Tristram, H. B. The Great Sahara: Wanderings South of the Atlas Mountains. 



London : 1860, 8vo, 

 is carelessly compiled, and includes the names of many species " not found by the 

 author, but given on the authority of trustworthy local naturalists." And it is to be 

 noticed that the author restricts the term "Sahara" to the High Plateaux and the 

 northernmost part of the desert, using the term " Desert " for the greater portion of 

 what is commonly called the Sahara. This explains how examples of several species 

 which are known not to extend south of the High Plateaux are labelled in the British 

 Museum as from Mr. Tristram's Collection made in the Algerian Sahara. This list 

 contains Naia hate 1, which has since been found round Biskra by M. Lataste, and, very 

 curiously, a Salamandra — ? from Tuggurt. However, no information is given as to 

 the source of these entries. 



Such was the state of our knowledge of the Herpetological Fauna of Algeria, when 

 Dr. Strauch published an excellent and most conscientious descriptive Catalogue, 

 entitled : — 



12. Strauch, A. Essai d'une Erpetologie de I'Algerie. Mem. Ac. St. Petersb. (7) iv. 



no. 7, 1862, 86 pp. 



This work is based upon the previous literature, the collections of the ' Exposition 

 permanente ' in Algiers, and the author's own collections made during several months' 

 stay in Algeria. A great many of the species enumerated on the authority of others 

 have to be erased, as based on errors of determination or of localities, so that of the 76 

 species included in the list only 56 (including two marine Turtles) deserve to stand. 



The additions are : — 



1. Euprepes vittatus, Oliv. (Mabuia). — Mzab. 



2. Eryx jacuhis, L. — Oran. 



3. Coronella austriaca, Laur. (=1 C. amalice, Boettg.). 



4. Zamenis cUffordii, Schleg. { = diadema, Schl.). — Sahara. 



5. Vipera avicennce. Alp. { = Cerastes vipera, L.). — Western Sahara. 



6. Vipera aspis, L. {^latastii, Bosca). — Algiers. 



13. Lallemant, C. Erpetologie de I'Algerie. Paris: 1867, 8vo. 41pp. 



This opuscule is principally an abridgment of Strauch's ' Essai," with notes on the 

 author's own collections.
