1892.] AND BATRACHIANS FROM BARBARY. 15 



The specimens from the first-mentioned locality belong to the variety 

 named bedriagce by M. Lataste, whilst the others, which are distin- 

 guished from them by being more slender and somewhat smaller, 

 may be taken as representing the variety deserti {Zootoca deserti, 

 Giinther). However, as Mr. Bouleuger 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. sGutellatus. 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.

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.

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. In specimens 

 presenting these two kinds of variation in the collar and in the
