first two upper labials; three loreals in a row between nasal and pre- 

 ocular, first in contact with the supranasal and frontonasal; second 

 with frontonasal, prefrontal, first supraocular, and first superciliary; 

 third with first superciliary ; a large subocular lying above and partly 

 between the fifth and sixth supralabials ; eight supralabials, the last 

 ones diminishing slowly in size; three temporals forming a semicircle 

 behind the eye, which continues on top of the head separating the 

 supraoculars from parietal and interparietal; mental very small, not 

 differentiated except by position from the neighboring infralabials, 

 followed by a large unpaired postmental; four pairs of chin shields, 

 the first three of which are in contact with the infralabials and with 

 their fellows; ear opening round, very small, not wider than one-sixth 

 the diameter of the eye opening on the left side of the head and smaller 

 still on the right side ; body exceedingly elongate, the adpressed limbs 

 failing to meet by more than twice their combined lengths; 35 scales

around the middle of the body; 110 dorsal scales in a straight line be- 

 tween the occipital and a point directly above the vent; 85 ventrals 

 from the anal plate to the center of the breast level with the axillae; 

 dorsal scales each with seven or eight striae, not forming keels, 

 however; laterals and ventrals with much weaker striae; preanal 

 scales not enlarged; limbs very weakly developed; the foreleg equaling 

 two-thirds the distance between end of snout and posterior border of 

 ear; four very short fingers, the third having five subdigital lamellae, 

 the third and fourth subequal in length; toes longer, the third much 

 the longest and having 10 subdigital lamellae each with a median 

 ridge; the lamellae of the other toes not ridged; scales on sole of foot 

 not spinose but rounded; tail (reproduced) nearly cylindric, ending in 

 a point, covered with scales like those of the body, about two-thirds 

 as long as the head and body; the two median scale rows underneath 

 the tail very slightly larger than the others.
