LACERTA MURALIS IN WESTERN EUROPE AND NORTH AFRICA. 365 
Var. VAUCHERI. 
A single male specimen of a lizard agreeing in most respects with the Tangier 
variety described further on as var. vaucheri was collected at Salir, Algarve, by 
Dr. Gadow, who has presented it to the British Museum. The dorsal scales are feebly 
keeled and not larger than those on the upper surface of the tibia; they number 76 
across the middle of the body, 3 and 4 transverse series correspond to the length of one 
ventral plate, and 57 to the length of the head. The ventral plates form 27 transverse 
series, in most of which the outer plate is divided, so that the longitudinal rows may be 
described as 8 in number. 10 plates in the collar, and 31 gular scales and granules in 
a line in the middle. Femoral pores 18-17; 28 lamellar scales under the fourth toe. 
30 scales in the fourth whorl behind the postanal granules. The specimen is 
anomalous in having only three anterior labials on the right side ; the masseteric shield 
is small and divided into two or three pieces. 
The back is greyish brown with a black network, the sides are black with round 
light spots; small black spots are present on the ventral shields.

Compared with the Tangier specimens on which this variety is primarily founded ', the 
lizard here described differs in its still finer lepidosis and in the division of the outer 
ventral plates—characters which probably could not be maintained as distinctive should 
a series of specimens be available. 
Var. MONTICOLA. 
A single female specimen collected by Dr. Gadow in the Serra Estrella, Portugal, at 
an altitude of about 6000 feet (Pl. XXIV. fig. 11), first struck me by its general 
resemblance, in form and markings, to the Caucasian vars. chalybdea and saxicola. It 
has also much in common with the newly described LZ. horvathi from $.W. Hungary.
