Head rather elongate and pointed ; the distance between the anterior angle of the 
eye to the tip of the snout equals the interval between the posterior angle of the eye 
and the ear; ear vertical, its height equalling the long diameter of the eye, not 
denticulated ; nostril defined by the first labial, a supranasal, and two postnasals ; 
supranasals form a broad suture behind the rostral ; frontonasal broader than long ; 
praefrontal suture almost as long as that of the supranasals ; frontal narrow posteriorly 
and grooved throughout its length ; two large supraocrdars separated from the pre- 
frontals and parietals by groups of small scales and from the superciliaries by a line of
