FROM THE CANARY ISLANDS, 683 
Temporal scutellation granular, often finely, with more or less 
developed masseteric and tympanic shields; a series of small 
supr atemporals. 
Scales covering the lower eyelid extremely small and granular, 
those in the centre scarcely, if at all, differentiated. 
Dorsal scales very small, rhombic- granular, more or less dis- 
tinctly keeled, 90-110 across the middle of the body; 3 or 4 
series corresponding to one ventral plate. 
Upper caudal scales much smaller than the dorsals. 
Gular scales 33-44 on a line between the collar and the third 
pair of chin-shields; gular fold distinct, collar not serrated, 
composed of 7-11 plates. 
Ventrals in 10 or 12 longitudinal and 29-31 Ponsvene series. 
Anal comparatively small. 
Femoral pores 24-31. 
Subdigital lamelle 30-36 under the fourth toe. 
Coloration (from life). Pileus of a dark or light bronze-brown, 
more or less profusely speckled with black. 
Superciliary streak, if distinct, on each side running entirely 
upon the parietal and continued to the base of the tail, or 
beyond; this streak of a bright yellow in life. 
A light streak along the spine, well defined from the bronze 
colour of the dorsal region. 
A short subocular streak, of a duller yellow than the super- 
ciliary, and often interrupted, extends a little way beyond the 
tympanum in the middle of the dark brown temporal band, 
which is edged below by a continuous dull yellow streak, extend- 
ing from below the tympanum to the base of the hind limb, 
reappearing again on the side of the tail. 
The dark bands in some specimens (young males) with small 
light, dark-edged spots without any tendency to form transverse 
series. Larger bright spots on the limbs. 
Lower surface of head blackish grey, or even black in full- 
grown specimens; the dark shade sometimes extending to the 
breast. Belly dirty white, or pale greyish, without any spots ; 
a few roundish, ileal white spots sometimes present on the 
margin. 
Frequently a small sky-blue spot on the dark temporal band 
above the insertion of the fore limb, another of the same colour 
on the upper arm. In a few adult females the whole lower 
surfaces of the thighs of the same bright blue. 
In some fully adult males the markings become very indistinct 
or may nearly entirely vanish, such specimens being blackish 
brown. 
Iris silvery. 
Habitat: Hierro, Canary Islands; a large number of speci- 
mens were collected by Dr. Caesar Boettger at Las Lapas, in 
the “ Golfo” of Hierro, and presented to me in August, 1913. 
The types, which I received alive, are preserved in my private 
collection. é 
This species belongs to the same group as the well known
