20 Lacertid.v. 



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

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

 have been obtained on the Eldame Kiver and at Tabora, East Africa. 



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

 of a gular fold, the even-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 nenmanni by Tornier, t. c. p. 376, appears to 

 differ only in having 2 supraoculars instead of 4. The following is 

 an abstract of the original description : 



Snout rather pointed, nasals not swollen. Nostril between three 

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

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

 frontonasal l)roader than long ; prefrontals forming a median suture ; 

 a deep groove along the frontal; interparietal l.j times as long as 

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

 supraoculars, preceded and followed by small scales, and separated 

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

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

 borders the mouth. Two elongate upper temporals. 



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

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



Scales sharply keeled, pointed, sul)imbricate, 46 across the body. 

 Ventral plates in 8 straight longitudinal and 26 transverse series. 

 Two rather large j^reanal plates, one in front of the other. 11 femoral 

 pores on each side. Caudal scales strongly keeled. 



The hind limb reaches the collar. Tail more than twice as long as 

 head and ])ody. 



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 on the body, the upper from behind the 

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

 bordering the tympanum below ; a black ])and between these two 

 streaks, bearing 8 blue spots. 



The type is preserved in the Berlin Museum.

Latastia htirii, Bouleng. Ann. & Mag. N. H. (7) xix. 1007, p. 393. 



Body much depressed. Head much depressed, fiat above, nearly 

 twice as long as broad, its depth e(|ual to the distance between the 

 posterior corner of the eye and the tympanum, its length 4 times in
