The occurrence in Southern Ehodesia of Eremias nitida, Grthr., a species 
inhabiting Nigeria and Togoland, has been reported by Hewitt and Power 
('Trans. E. Soc. S. Afr.' iii, 1913, p. 156), and seemed so highly improbable 
to me that I applied to Mr. Power for the loan of the specimen on which 
the identification was based, and this favour was most obligingly granted 
by Miss Wilman. The result of my examination is that the lizard is no 
Eremias, but a Latastia, a genus established' by Bedriaga for species 
formerly confounded with Lacerfa, but which differ in having keeled sub- 
digital scales — a character in which they agree with Eremias. The only 
character separating the latter from Latastia is the position of the nostril, 
widely separated from the first upper labial shield, which is not the case in 
the lizard from Eldorado, here described as a new species, with which the 
name of its discoverer, Mr. O; A. Kidwell, is associated. The discovery is 
a very important one, as it extends the range of the genus, previously 
unknown from South Africa. 
Latastia kidwelli, sp. n. 
Body scarcely depressed. Head moderately depressed, 1^ times as long 
as broad, its depth equal to the distance between the centre of the eye and 
the tympanum, its length 4^ times in length to vent ; snout obtusely 
pointed, as long as postocular part of head, with sharp canthus and vertical 
loreal region. Pileus If times as long as broad. Neck as broad as the 
head. Hind limb reaching the shoulder ; foot 1^ times as long as the head ; 
toes slender, compressed. 
Nostril pierced between 4 shields ; nasals forming a suture behind the 
rostral, the suture f the length of the frontonasal, which is much broader 
than long and broader than the internarial space ; prefrontals forming a 
median suture ; frontal slightly longer than its distance from the end of the 
snout. If times as long as broad, rounded in front, much narrower behind, 
grooved along the anterior | ; parietals IJ times as long as broad, with 
straight outer border ; interparietal 2-^ times as long as broad, separated 
from the small occipital by a very small shield. Four supraoculars, first
