In the same part of the Pyrenees, but at a much lower altitude, I captured in June 

 1S78, on a wall in the town of Bagneres de Bigorre, a rather remarkable specimen, 

 preserved in the Brussels Museum, which my colleague M. Dollo has had the kindness 

 to send me for re-examination. It is a female of large size (72 millim. from snout to 

 vent), which attracted my attention by the presence of a large black ocellus with blue 

 centre, above the axil, well displayed as the lizard sunned itself on the old wall. 



Head once and two-fifths as long as broad, much depressed 1 , its depth equal to the 

 distance between the posterior border of the eye and the tympanum. Hind limb reaching 

 the elbow of the adpressed fore limb ; foot once and one-fourth as long as the head. 

 Frontal shield nearly as long as its distance from the end of the snout ; series of 

 supraciliary granules complete ; occipital much smaller than the interparietal ; masseteric 

 disk rather small. 21 gular scales and granules on the median line ; collar with 

 entire edge, formed of 10 plates. Dorsal scales granular, flat, smooth, faintly keeled 

 towards the tail, a little larger on the back than on the sides, where 3 correspond to a 

 ventral plate ; 55 scales across the middle of the body ; 28 transverse series correspond 

 to the length of the head. 29 transverse series of ventral plates. Scales on upper 

 surface of tibia distinctly keeled, smaller than dorsals. Femoral pores 17 on each side. 

 2G lamellar scales under the fourth toe. Caudal scales obtusely keeled, very obtusely 

 pointed behind ; the fourth whorl behind the postanal granules contains 36 scales. 

 Colour grey-brown above, with a dark brown lateral band bordered above and below 

 by a white streak ; a few blackish dots irregularly scattered on the back ; above the axil, 

 the lateral band is interrupted by the large ocellar spot mentioned above ; belly 

 without spots. 



A side view of the bead and anterior part of the body of this specimen (enlarged 

 2£ times) is given on PI. XXV. fig. 7.
