Habitat. — The type iu the Berlin Museum is from Porto Novo, 

 Slave Coast, Guinea ; other specimens i-eferred to the same species 

 have been obtained on the Eldauie Eiver and at Tabora, East Africa. 



Appears to be well distinguished from L. johnstoidi by the presence 

 of a gular fold, the eveu-edged collar, the shape of the frontonasal 

 shield, and the arrangement of the light streaks. 



The lizard from the Brussa Valley, north of Lake Stephanie, 

 described as Eremias nemnanni by Toi-uier, t. e. p. 376, appears to 

 differ only iu having 2 supraoculars instead of 4. The followiug is 

 an abstract of the original description : 



Snout rather pointed, nasals not s"wollen. Nostril between three 

 shields, a nasal and two postnasals, the lower of which does not reach 

 the rostral ; nasals iu contact with each other behind the rostral ; 

 frontonasal broader thau loug ; prefrontals forming a median suture ; 

 a deep groove along the frontal; interparietal l.V times as loug as 

 broad, separated from the occipital by a small shield. Two large 

 supraoculars, preceded and followed liy small scales, and separated 

 from the superciliaries by a series of granules. 5 or 6 upper laliials 

 anterior to the subocular, which is but little narrower beneath and 

 l)orders the mouth. Two elongate upper temporals. 



5 pairs of chin-shields, the two anterior in contact iu the middle. 

 A distinct gular fold. Collar free, formed of 10 plates. 



Scales sharply keeled, pointed, subimbricate, 46 across the body. 

 Ventral plates in 8 straight longitudinal and 26 transverse series. 

 Two rather large preanal plates, one in front of the other. 11 femoral 

 pores on each side. Caudal scales strongly keeled. 



The hind limli reaches the collar. Tail more thau twice as long as 

 head and liody. 



Back greyish brown with black spots ; a white dorsolateral streak, 

 uniting with its fellow on the base of the tail ; two white lateral 

 streaks, broken up into spots ou the body, the upper froiu behind the 

 eye, bordering the tympanum above, the lower from the upper lip,
