90 REPTILES AND BATRACHIANS 



Supra-oculars three, followed by a small shield, which is 

 the first of four small shields bordering the parietals at 

 the outer side. Behind each of the parietals and also behind 

 the interparietal two small scales. One loreal bordered 

 inferiorly by a small shield, being the first of a row of five 

 small infra-orbitals. Seven upper- and six lower-labials. 

 Earopeniug exposed. Temporal scales irregular, rather large. 

 All the shields of the head smooth, without keels, but most 

 of them provided with several small pits. 



Chin-shields very large, the three anterior pairs forming 

 a suture, behind these chin-shields two rows of rather small 

 roundish scales, followed by a double longitudinal row of 

 large gulars; collar-shields five in number, smaller than the 

 gulars. Behind the rather indistinct collar the abdominal 

 shields begin with a row of eight shields, viz. two large 

 ones in the middle, flanked on each side by three smaller 

 ones, which are arranged in a triangle. Fifteen transverse rows 

 of abdominal shields, those of the four inner longitudinal 

 rows very large, longer than broad, strongly rounded and 

 overlapping posteriorly ; the shields of the outer rows of 

 abdominal shields gradually diminishing in size. A trans- 

 verse row of three praeanals. Between these praeanals and 

 the last row of (four) abdominals four small shields two 

 on either side, each provided with a praeanal pore. 



Dorsal shields narrow, hexagonal, lanceolate, imbricate, 

 keeled in twenty-five rows beginning directly behind the 

 parietals down to the sacrum '). Thirty nine rows of shields 

 round the middle of the body, including the ventrals. 

 Forelimbs with large shields, granulate under the arms, 

 hind limbs with large shields anteriorly and inferiorly, 

 hinder thighs granulate; five femoral pores on the right-, 

 four on the left side. 



Tail without groove along the sides, shields narrow forming 

 regular verticillae, the upper and lateral ones keeled, sharply 

 pointed, the lower ones smooth and rounded posteriorly. 



1) Including the row with the white spot, on the sacrum (see figure).
