Dum. & Bibr. loc. cit. p. 278 ; Gray, Cat. Liz. p. 38 ; Strauch, loc. 

 cit. p. 38 ; Bouleng. loc. cit. p. 182. 



Three or four palpebral shields. Infraocular not reaching the 

 lip. Front edge of the ear strongly toothed. Dorsal scales very 

 much larger on the hinder part of the back, imbricate, strongly 

 keeled. Ventral plates broader than long, in 10-12 longitudinal 

 rows. Digital denticulations very long.

3. ACANTHODACTYLUS CANTORI. (Plate LXIV. fig. 3). 



Acanthodactylus cantori, Giinth. Kept. Brit. lud. p. 23 ; Stoliczka, 

 Journ. As. Soc. 1872, pt. 2, p. 91 ; Blanf. E. Persia, Zool. p. 381. 



This species resembles very much A. hoslcianus. The shape of 

 the head is different, the snout being here longer and acutely pointed ; 

 the fronto-nasal and prsefrontal shields are consequently more 

 elongate. As a rule, there is a greater number of longitudinal rows 

 of ventral plates, viz. 12-14. The front edge of the ear is never 

 jstrongly toothed.

4. ACANTHODACTYLUS MiCROPHOLis. (Plate LXIII. fig. 3.) 

 Acanthodactylus micropholis, Blanf. loc. cit. p. 283, pi. xxvi. f. 2. 

 Three or four palpebral shields, the front one frequently separated 



from the following by a row of granules. Infraocular generally 

 forming part of the lip. Front edge of the ear slightly toothed. 

 Dorsal scales granular on the neck and between the shoulders, larger, 

 semioval, and sharply keeled on the rest of the back. Ventral 

 shields broader than long, in 10-12 longitudinal rows. Digital 

 denticulations not very long. 

 Hab. Baluchistan. 



5. ACANTHODACTYLUS SYRiACUs. (Plate LXIII. fig. 4.) 



Acanthodactylus hoskiana, var. syriacus, Boettger, Ber. Senck. 

 Ges. 1878-79, p. 69. 



Acanthodactylus savignyi, part., Boettger, Jahresb. Senck. Ges. 

 1879-80, p. 178 (specimens from Syria). 



Four palpebral shields. Infraocular not reaching the lip. Tem- 

 poral scales imbricate, keeled. Front edge of the ear slightly toothed. 

 Dorsal scales slightly keeled on the neck and between the shoulders, 

 larger, semioval and acutely keeled on the rest of the back. Ventral 

 plates broader than long, in 10-12 longitudinal rows. Digital 

 denticulations not very long. 



This species is very closely allied to A. micropholis, from which it 

 may be distinguished by the larger, imbricate, and keeled scales of 

 the temporal region, and the more acute keel of the dorsal scales. 



A. syriacus is known to me from the description of Boettger, and 

 from one specimen collected in Palestine by Dr. Anderson. 



Hah. Syria.
