" Tlie Eremias riihro punctata which yon collected do not differ from Egyptian and 

 Tripolitau specimens. According to Anderson {Zool. ^-gfJl't), Egyptian examples 

 have 53 to 66 + 12 scales ronnd the body. In fonr of your specimens, in wnich 

 I have counted the scales, I find 58, 60, 61, 65 + 12." 



14. Eremias guttulata iLicht.). 



I,(veriu giilhiliila Lichtenstein, Vers. Douhl. itus. BcrUn. p. 101 (1823— Egypt and Nubia). 

 Found in the sandy ])arts between El-Golea and Fort Miribol. 



15. Scincus oflBcinalis Lanrenti. 



The " Sandfish," as the Skiak is called by the French, is common in the sandy 

 Sahara at Touggourt, from Tonggourt to El-Oued, between Ghardaia and El-Golea, 

 at El-Golea, and north of the latter. 



In Tidikelt we did not receive or see a single specimen of Scincus o//icinalis.

Chalcides .vjioi'ilis varictas Knenig, I.r. p. 414. 



Common at In-Salah and Igostcn. Habits like those of Scinctia ofjicinalis. 

 Koenig obtained specimens at and near Ouargla (El-Hobra) and Tonggourt, where 

 I did not collect reptiles in 1012. 



Boettger named the two sjjecimens from El-Hobra (between Ouargla and 

 Ghardaia) and Ouargla •• Ch. boiileiif/fri," while he says of the Tonggourt specimen : 

 " Mit 26 lieihen, aber mit Kopfpholidose von sepo'irlesl Ich wiirde die Form 

 trotzdem zu tioiiU'iiijcn stellen 1 Uebergangsform 1 " 



Mr. Boulenger kindly sent me the following note about these specimens : 



" The Chalcides sepoidcs from In-Salah differ from the typical form, and agree 

 with Ch. boulengeri, Anderson, from S. Tunisia, in the fifth labial entering the eye 

 instead of the fourth ; in one specimen there are even six anterior labials on one 

 side. Agree with the ty]iical form in the position of the nostril, anterior to the 

 suture between the nostril and the first labial, and in the nnmber of longitudinal 

 series of scales — viz. 24 or 26. 24 is the usual nnmber in the typical form, whilst 

 it is the exception in the In-Salah series (3 cases out of 17). In all the limbs 

 are pentadactyle. 



" The name var. intermedia might be used to designate these specimens (also 

 found at Biskra) connecting the typical Chalcides sepoides of Egypt with Ch. 

 boulengeri.'''' 



IT. Chamaeleon vulgaris Haml. 



The I'liamaok'on ajipears not to inJiabit, as a rule, (he real desert, but it cxleiids 

 into the northern jiortion of it. It occurs near Biskra, and Koenig found a specimen
