slightly concave posteriorly; frontal once and one-fourth as long as 

 broad, twice as broad as the supraoculars, in contact broadly with the 

 first three; a pair of frontoparietals separated widely from each other 

 by the posterior prolongation of the frontal; parietals large, almost 

 twice the size of the interparietal, separated from the supraoculars by 

 two small scales and the frontoparietals, and from each other by the 

 shield-shaped interparietal and the fan-shaped occipital, which is about 

 two-thirds the size of the interparietal; five supraoculars, the second 

 the largest; a single nasal in contact with the first upper labial, which 

 separates it completely from the rostral; three loreals in a row between 

 nasal and preocular, first in contact above with supranasal and fron- 

 tonasal; second with frontonasal, prefrontal, barely with the first 

 supraocular, broadly with the first superciliary ; third with first super- 

 ciliary ; a long subocular lying above and partly between the fifth and

sixth supralabials ; 10 supralabials, the last one scarcely distinguish- 

 able from surrounding scales; five temporals in the first row, forming 

 a semicircle behind the eye; mental very small, scarcely differentiated 

 except by position from the neighboring infralabials, followed by a 

 somewhat larger, unpaired postmental; four pairs of chin shields, the 

 first two pairs of which are in contact with the infralabials and with 

 each other; no external ear opening, but where it might have been the 

 region is indented to a slight extent and is covered by very small 

 scales; body elongate, the adpressed limbs failing to meet by a distance 

 equal to two-thirds their combined lengths; 40 to 42 scales around the 

 body anteriorly lessening to 35 at midbody; dorsals with about 10 

 heavy striae (almost amounting to fine keels) to a scale; laterals less 

 heavily striated; 110 dorsal scales in a straight line between the occipital 

 and a point directly above the vent; 70 ventral scales from the anal 

 plates to the center of the breast level with the axillae; laterals very 

 faintly striated ; ventrals perfectly smooth ; the body scales sometimes 

 uneven in size and irregular in shape so that rows do not run perfectly 

 parallel; preanal scales very slightly enlarged; limbs short and poorly
