Lizards of the Familij LacertiJfe. 270 



below tlie eye, through the ear, to above tlie axil; white, 

 black-edged ocellar spots on the posterior part of the back, 

 on the hind limbs, and on the tail ; lower parts white. 



From snout to vent 38 ram. 



This species, which I regard as the most primitive of the 

 genus, as it is also the northernmost in its habitat, is based 

 on a single male specimen, probably half-grown, from the 

 East Coast of Lake Tanganyika, presented to the British 

 Museum by Mr. W. H. Nutt in 1896. 



Eremias adramitana. 



Head and body strongly depressed, limbs very slender ; 

 liead 1^ times as long as broad ; snout pointed, with the 

 nasal sliields rather strongly swollen, as long as broad, as 

 long as the postocular part o£ the head ; hind limb reaching 

 between the collar and the ear in males, the shoulder or 

 the collar in females ; foot Ig- to 1^ times as long as the 

 head ; toes slender, feebly compressed ; tail 1| to 2^ times 

 as long as head and body. Lower eyelid with a semi- 

 transparent disk divided into 5 to 8 scales. Lepidosis as in 

 E. guttulala, but occipital minute or absent, the parietals 

 meeting in the middle, and ventral plates in 10 regular 

 longitudinal series, mostly as long as broad or a little 

 broader than long, the outer longer than broad. 31 to 40 

 scales across the middle of the body. 11 to 15 femoral 

 pores on each side. Subdigital lamellee tricarlnate, 20 to 23 

 under the fourth toe. Fawn-coloured or pale grey above, 

 with or without small brown spots, whicli may be irregular 

 or disposed in two longitudinal series on the back, with or 

 without small whitish spots ; a dark brown lateral band, 

 often bearing white spots, from behind the eye to the tail, 

 bordered below by a white or yellowish lateral streak passing 

 tln'ough the tympanum ; upper surface of limbs marbled 

 with brown, or with white spots ; lower parts white. 



From snout to vent 44 mm. 



This species has been confounded with E. brevi'rostrift, 

 Blanf., of which the Syrian J^. hernoulli, iSchenkel, is a 

 synonym, by Anderson, ' Herpetology of Arabi;i,' p. 43 

 (189G). It diiiers in the more depressed head, longer in 

 proportion to its width, the more slender limbs, and the ventral 

 ])lates constantly in ten longitudinal series. It is oidy known 

 from the Hadramut, South Arabia, whilst E. hrevirostris is 

 on record from Kalabagh in the Punjab, Bushire in Persia, 

 Tumb Island in the Persian Gulf, and Syria.
