116 ME. G. A. BOULEKGEE ON THE EEPTILES 



measuring up to lOo niillim. from snout to vent, a somewhat longer and more pointed 

 head, finer granulations between the tubercles and on the throat, and the very pale, 

 yellowish-white coloration, without or with very indistinct pale brown spots. 



This Gecko, common all round the Mediterranean, is found all over Barbary, north 

 and south of the Atlas; it frequents houses, old walls, and cliffs. 



The typical form is figured in Bonaparte's ' Fauna Italica,' and the var. deserti on 

 Plate XIII. fig. 3 of this Memoir. 



'2. Tarentola neglecta, Strauch, 1887. 

 T. migusticeps , Strauch, 1887. 



This species, which in its physiognomy reminds somewhat of Hemidactylus turcicus, 

 was recognized as distinct by Lataste, whose description was, however, anticipated by 

 that of Strauch. 



The head is smaller than in T. mauritanica, the temples usually less swollen, and the 

 scales on its upper surface larger, smooth or feebly keeled ; 10 to 12 scales in a trans- 

 verse line between the eyes ; tubercles on the temple small and feebly prominent. x\ll 

 the tubercles on the back, the sides of the neck and body, and on the limbs much less 

 prominent, never conical ; and the dorsals are entirely isolated, not surrounded by 

 smaller ones ; the granules between the tubercles larger. Lateral ventral fold absent 

 or very indistinct. Digits less dilated, with subparallel lateral borders. Caudal 

 tubercles less developed. Pale brownish or yellowish white above, without or with 

 small brown spots or interrupted longitudinal lines ; head usually with four to six 

 brown longitudinal lines, most distinct on the snout ; tail with more or less distinct 

 darker cross-bands ; lower parts white. 



This is a small species, the largest of many examples examined by M. Lataste measuring 

 -JO millim. from snout to vent; tlie usual length is 45 millim. from snout to vent, 

 tail 50. 



T. neglecta was found in abundance by Lataste in the sandy Sahara in Algeria 

 between El Mala and Arifji, and at Wargla, on old palm-trees, never about houses 

 or walls like its larger congener. I have also received a specimen from Kef el Dhor, 

 between Biskra and Tuggurt. It would appear, however, that the species occurs also 

 on the Plateaux, for Dr. Strauch's specimens were purchased as from Batna.
