Lataste, whilst the others, which are distinguished from them by being more slender and somewhat smaller, may be taken as representing the variety deserti {Zootoca deserti, Giinther). However, as Mr. Boulenger points out, not only are these varieties ill-defined, but the former approaches A. vulgaris in its structure and coloration, whilst the latter often closely resembles A. scutellatus. This species {A. pardalis) is thus a transitional form. Among the specimens recorded above, the scales round the middle of the body, including the ventrals, vary from 61-74, whereas in Mr. Boulenger's specimens the variation is from 66-82. The femoral pores also are variable, as in my specimens the lowest number is 15 and the highest 22, whilst the numbers recorded by him are 15-25. 14.

In these specimens the subocular enters the labial border, and in five out of the seven it does so more or less broadly. In one of the remaining two the sharp lower angle of the shield is wedged in between the labials as a fine point, while in the seventh specimen it is excluded from the labial border on one side, but preserves the same character as the previous specimen on the opposite side. Unlike Moroccan examples of this lizard, the tendency of this shield is to enter largely into the formation of the lip. In none of the specimens does the number of the scales round the body, including the ventrals (8), exceed 77, nor fall lower than 73. The femoral pores vary from 23 to 26. They are marked with six longitudinal whitish lines, separated from each other by broad dark brown bands ; but in the largest specimen the white lines are more or less broken up into white spots, the intervening dark bands being reticulated with brick-red. The limbs are white spotted, and the end of the tail is pink. Genus EREMIAS, Wiegmann. 15.

These three specimens have the median disk of the eyelid broken up into 4, 5, and 6 scales respectively, with the collar distinct only at the sides. In the variations tabulated by Mr. Boulenger, the form with the collar distinct at the sides has only two scales in the transparent palpebral disk, the highest number, four, recorded by him occurring in specimens with the collar free all round.
