11. Acanthodactylus pardalis Licht. 



The distribution of this species in Algeria has been rather imperfectly 

 known. Koenig (t.c. y. 411) says only that it is " weit in die Sahara hineingehend," 

 while Werner (]'erk. zuol.-bot. Ges. Wicn, xliv. p. 82) says " geht nach Siiden etwa 

 bis Chegga." 



I have found the species much farther southwards, i.e. between Ouavgla 

 and El-Golea, and near Guerrara, between the Oued N(,'a and El-Alia, on the way 

 from Ghardaia to Touggourt. It appears, however, to be rarer than ^4. boskianus 

 and scutellatus, but might sometimes have been mistaken for either of them. 



There is evidently an ill-detined Saharau race which might have to be called 

 .4. pardalis dc^erti (Giinther), unless the name dese/ii were preoccupied by the 

 Lacerta deserti of Lepechin. From the excellent notes by Anderson (^Reptiles of 

 Egypt, p. 154) it would appear that the Saharan race was quite recognisable, 

 though intermediates between it and the northern form were found. Koenig's 

 note also supports the view that two forms are separable, but Mr. Boulenger 

 apparently does not believe in their distinctness, as he named my specimens 

 only " Acanthodactylus pardalis." 



12. Acanthodactylus scutellatus Aud. 



Cf. Boulenger, I.e. p. 130 (" Saharian examples are smaller, more slender aud lighter-coloured than 

 the typical form from Egypt"); Oit. Lizanh Brit. Mus. iii. p. db ("a smaller variety, var. 

 exigiia Lat. = iitornata Gray, apparently restricted to the Sahara") ; Werner, Verh. kk. zooh- 

 bot. Ges. Wieii, xliv. 18'J4. p. S2 (" Kommt in zwei stiindigen Varietaten vor, in einer 

 kleineren von Biskra bis Mraier, und einer grosseren von Mraier bis Temacin. Die grossere 

 ist die normale dunkel reticulirte Form, die kleinere entbehrt dieser Zeichnung ") ; Koenig, 

 t.c. p. 410 (speaks also of two varieties, the smaller of which he found among the dunes) ; 

 AndevsoD, Jiejilile.'s of Eiji/pt, p. 163; Doumergue, Bull. Soc. Geogr. et Arch. Oran, xix.-xxi. 

 pp. 153-60! 



This lizard is common enough in the (Central Sahara. We caught specimens 

 at Oaargla, between Ouargla and El-Golea, at El-Golea, Fort Miribel, and as far 

 south as In-Salah ! Also near Guerrara, between the Oued N(;a and El-Alia. 



Mr. Boulenger says (in litt.) : "The specimens from In-Salah represent 

 the typical form. The others belong to the smaller, ill-defined var. inornatiis 

 V. exiguus.'" 



13. Eremias rubropunctata (Licht.). 



Lacerta ruhropunctala Lichtenatein, Vers. Doubt. Berl. Mas. p. 100 (1823— Egypt and Nubia) ; 

 Koenig, liiisen und Forsch. in Algerien, pp. 93, 412) ; Anderson, Zool. Egypt, Reptiles, 

 pp. 183-G. 



I found this species common in the Central Sahara. It was first obtained 

 about r)(j km. north-east of El-Golea, then between El-Golea and Fort Miribel, 

 and it was common on the Oued Saret. We did, however, also catch it near 

 Foggargt-es-Zona, the lujrtlieriniifist ol' the Tiilikelt oases. It inhabits chiefly 

 the Ilammada. 



LTntil Prof. Koenig obtained it near Ouargla, this species was not Unown to 

 occur in th(^ Western Sahara, or anywhere; <!ast of Egypt. Since then it, has jjeen 

 found in Tripoli, liottger not iced some dilferences in the scaling between Koenig's 

 specimen and those in the Seuckeubcrg Museum, but tiieso differences are not 

 peculiar to western examples, and not constant. Mr. Boulenger (in litt.) says ;
