sand)', witli small brown spots ; a brown streak on the side of the head and neck, 

 [)assing through the eye; lower parts white. 



From snout to vent 6G millitn., tail 38. 



The type specimens are from Wadi M'bellem, Tripoli. The same Lizard has since 

 been found in Tunisia ; one specimen at Taferma by M. Letourneux, one between 

 Cabes and Gafsa by M. Sedillot, one at Oum-ali, near Gafsa, and another at Bou 

 Hedma by M. Valery-Mayet. 



Described in detail and figured by Peters, Mon. Berl. Ac. 1880, p. 306, pi. — . fig. 1. 



3. Saurodactylus, Fitzinger, 1843. 



Digits not dilated, clawed, not denticulated laterally, inferiorly with a series of 

 smooth lamellffi. Dorsal scales small, subimbricate. Pupil vertical. No femoral or 

 prseanal pores. 



This genus is very closely allied to Tropiocolotes, differing mainly in the smooth 

 subdigital lamella, the absence of a distinct lateral digital denticulation, and the smaller 

 dorsal scales. A single species is known, which was formerly referred to the genus 

 Gymnodactjjlus. 



1. Saurodactylus mauritanicus, Dum. & Bibr., 1836. (Plate XIII. fig. 1.) 



Habit lacertiform. Snout subacuminate ; ear-opening small, roundish-subtriangular. 

 Nostril pierced between the rostral, the first labial, and three nasals ; five or six upper 

 and four or five lower labials ; mental followed by a pair of chin-shields. Scales on the 

 head small and granular, the granules largest on the snout ; dorsal scales small, smooth, 

 flat, roundi.sh, subimbricate, increasing in size towards the belly, where they are large, 

 roundish-he.xagonal, and imbricate ; about 70 scales round the middle of the body. 

 Tail a little longer than head and body, tapering to a fine point ; caudal scales cycloid- 

 imbricate, with the median inferior series transversely enlarged. Grey-brown above, 

 with small white dark-edged ocelli ; a dark brown streak on the side of the head, 

 passing through the eye; lower parts white; tail yellowish with brown spots, or 

 brownish with round yellow spots. 



From snout to vent 30 millim. 



This species is now represented in the British Museum by seven specimens collected 

 at Mogador by Lieut. Quedenfeldt. Boettger has recorded it from Djebel Iladid, near 

 Mogador, from between Mogador and Morocco, and from the Plateau of Chiodma. 

 Dumeril and Bibron's statement that the type specimen came from Algiers requires 

 confirmation. Two specimens were obtained at Nemours (Prov. Oran) by M. Gazagnaire 

 in 1888, and are now in M. Lataste's collection. Strauch saw specimens from the 

 Algerian Sahara in the Loche collection, and F. Miiller records the species from the 

 Plateau of Sersou, in the Province of Algiers.
