Bedriaga has briefly alluded to this small form, which he observed 

 alive at Valencia, on the road to the Dehesa de la Albufera, and which 

 struck him as remarkable for the extremely small dorsal scales and 

 smooth caudal scales, the middle dorsals of which are more or less 

 enlarged. The colour is described as a pale yellowish brown above, 

 with a brown, white-edged lateral band, greyish or yellowish beneath. 

 Length from snout to vent 49 millim. 



Among numerous specimens from Valencia which are preserved in 

 the British Museum and in the Lataste Collection, some agree with 

 Bedriaga's description in having the upper caudal scales very faintly 

 keeled, almost smooth, and the granular dorsal scales are very minute, 

 scarcely larger than those on the upper surface of the tibia. Some 

 specimens, however, have the dorsal scales larger, and the caudal scales 

 distinctly, though rather feebly, keeled, and yet evidently belong to the 

 same form. 



Although I have bestowed a name on it, I do not think it possible to 

 sharply define this form, which may be sa.id to connect the typical 

 L. muralis with the var. hispanica. 



Proportions and shape of head as in the typical form, snout pointed ; 

 the depth of the head equals the distance between the anterior corner 

 or the centre of the eye and the tympanum ; hind limb reaching the 

 axil, the shoulder, or the collar in males, the elbow or the axil in 

 females ; foot a little longer than the head ; tail If to 2 times as long 

 as head and body. 



Rostral not touching the nostril* ; frontonasal rarely in contact with 

 the frontalt ; frontal as long as or shorter than its distance from the 



* In contact with the frontonasal in two specimens from Valencia, and in one 

 from Foyos.
