LIOLAEMUS NITIDUS. 337 



under the sub- and anteorbitals. The inferior rim of the orbit is almost 

 exclusively formed by an elongated, curved, and ridged plate, with a 

 small one anteriorly, the anteorbital, and a thin diminutive one pos- 

 teriorly, the postorbital. The rest of the posterior rim is formed by 

 very small plates, passing gradually to the moderate, keeled, poste- 

 riorly obtuse scales which cover the temporal region. 



The rostral plate is quite narrow, and transversely elongated. It is 

 followed, on either side, by five upper, narrow, and elongated labials, 

 increasing in size to the fourth, which is the largest : the fifth being 

 the smallest, subtriangular, and somewhat overlapped by the fourth. 

 There is but one series of supralabials, composed of six narrow and 

 elongated plates, somewhat smaller than the labials, increasing in size 

 to the fifth, which is the largest : the sixth being nearly equal to the 

 first, though shorter and broader. The symphyseal is hemidiscoid, 

 and larger than the rostral. The lower labials, five on either side, 

 are elongated and narrow, largest anteriorly (larger also than the 

 upper labials), and gradually diminishing to the fifth, which is exigu- 

 ous. Four pairs of mental shields may be observed : the shields of 

 the anterior pair, contiguous upon their inner edge, and adjoining 

 the symphyseal and first lower labial, whilst the remaining pairs are 

 diverging posteriorly. An irregular double series of elongated infra- 

 labial scales exists between the mental shields and the lower labials. 

 The scales on the chin and throat are well developed, posteriorly 

 rounded, subequal, and nearly as large as the abdominal ones. 



The auricular aperture is large, vertically subovate, provided ante- 

 riorly with projecting scales, giving to that edge a denticulated appear- 

 ance. The scales on the sides of the neck are well developed, sub- 

 acuminated and keeled, and nearly equal to those of the upper surface 

 of the same region. The scales adjoining the occipital plates are 

 somewhat smaller than the following ones. Those of the upper region 

 of the body are subequal, conspicuously keeled, and acuminated, con- 

 stituting longitudinal series : the lateral ones converging upwards 

 towards the pelvic region and base of the tail, where they are still 

 more acute posteriorly. Upon the inferior region, they are smooth, 

 subequal, rounded posteriorly, being likewise smooth and subequal 

 under the hind limbs, keeled and subacuminated above, and nearly 

 as large as on the back. The posterior aspect of the thigh is wholly 

 granular, somewhat more coarsely inferiorly. The axilla is minutely 

 granular, whilst small and obtuse scales exist under the arm, some-
