Head (PI. XXVIII. fig. 6) about once and a half to once and two-thirds as long 

 as broad, moderately depressed, its depth in the tympanic region equalling the distance 

 between the anterior border or the centre of the eye and the anterior border of the 

 tympanum ; snout pointed. Neck as broad as the head. Body moderately depressed. 

 Hind limb reaching the collar or between the collar and the ear in males, the 

 shoulder or the collar in females ; foot once and one-fourth to once and a half as 

 long as the head; toes rather long and slender, more compressed than in the typical 

 form. Tail once and three-fourths to twice and one-fifth as long as head and body. 



Rostral shield narrowly separated from the nostril or, frequently, entering it ; nasals 

 forming a suture behind the rostral l ; frontal as long as its distance from the end of 

 the snout ; a series of granules between the supraciliaries and the two principal supra- 

 oculars, this series either complete or beginning behind the first supraciliary 2 ; parietals 

 once and one-fourth to once and a half as long as broad, often 3 not touching the 

 upper postocular; occipital often as long as and broader than the interparietal; a 

 single postnasal 4 ; temporal scales small and granular; tympanic and masseteric plates 

 always present, the latter separated from the parietal by one to three series of scales ; 

 upper temporal shield small, often broken up into scales ; normally four labials anterior 

 to the subocular 5 . 



Collar even-edged, with 9 to 13 plates ; gular fold distinct ; 27 to 40 scales on a line 

 between the symphysis of the chin-shields and the median collar-plate. 



Dorsal scales small, round or oval, very convex, smooth or feebly keeled, 56 to 75 

 across the middle of the body, 3 and 4, 4, or 4 and 5 transverse series corresponding to 

 one ventral plate, 40 to 57 to the length of the head. Ventral plates in 6 longitudinal 

 series 6 . Anal plate rather small, usually bordered by two semicircles of small plates. 



1 I have noted two exceptions, in specimens from Orezza and Ajaccio, in 'which, the rostral forms a narrow 

 suture with the frontonasal, and Mehely mentions another in a specimen from Bonifatto, Corsica. 



2 The series is complete in 20 specimens out of 45 from Corsica, and in 4 out of 13 from Sardinia. 



3 In 11 specimens from Ajaccio, and in one from Corte, Corsica. 



4 F. Miiller (Verh. nat. Ges. Basel, vii. 1882, p. 156) has mentioned two postnasals in two specimens from 

 Ajaccio, but this appearance is simply due to the intercalation of a small shield between the nasal and the 

 loreal, well above the nostril. 



5 Five on both sides in two specimens from Ajaccio, five on one side only in three specimens, and three in 

 two specimens. 



6 In one specimen from Corte, Corsica, a few of the plates of the outer row are divided iuto two.
