Description of holotype-—Head not flattened, nearly as thick as 
broad; an elongate, narrow interparietal in contact with frontal; on 
each side a parietal, no larger than scale following; 2 frontoparietals 
on each side, a little smaller than parietals, the anterior broadly in 
contact with frontal; a pair of large prefrontals, and 2 pairs of inter- 
nasals; 5 large inner supraoculars, the anterior separated from pos- 
terior internasals by contact of loreal and prefrontal; 3 small outer 
supraoculars, the posterior bordering orbit immediately in front of 
posterior supraocular of inner series, the other 2 not reaching orbit; 
posterior superciliaries missing, the series represented by 3 scales sepa- 
rating the anterior 2 outer supraoculars from orbit, and separating 
preocular from anterior inner supraccular; a very elongate supra- 
nasal; a single postnasal; a small lower loreal, bordered above by an- 
other loreal more than twice as large; a large preocular; two sub- 
oculars, the posterior elongate ; 3 postoculars: ; supralabials 10-10, the 
last elongate, none posterior to eye higher chan those anterior to eye; 
3 anterior temporals. 
Ten infralabials to a point even with posterior supralabial; about 
five pairs of chinshields, the scales of the anterior two pairs in contact 
medially, the remainder widely separated; a row of large labiomentals, 
larger than the infralabials they border, separating all of chinshields, 
except the anterior and a narrow portion of the second, from infrala- 
bials. 
Lateral fold deep, both on neck and on body; fold on neck enclos- 
ing a small, nearly scaleless pocket medially; 16 longitudinal rows of 
dorsals; 12 rows of ventrals; 42 dorsals from interparietal to posterior 
margin of thighs; 6 median rows of dorsals obtusely keeled, others 
smooth. 
Snout to vent, 116 mm.; tail regenerated; snout to posterior border 
of ear 29 mm.; width of head 20 mm.; depth of head 17 mm.; hind 
leg 32 mm.; foreleg 26 mm. 
No dark markings above or below; head reddish yellow ; body brown- 
ish yellow; venter cream. No light flecks present. 
Variation —All specimens have 16 rows of dorsal scales, and all but 
1 (with 14) have 12 rows of ventral scales; dorsals from occiput to 
base of tail 40 to 50, average 42.7 (40, 1; 41, 3; 42, 5; 48, 3; 46, 1; 
50,1). The number of keeled rows of dorsals varies from 6 to 8, and 
usually is 6. Two have 2-2 loreals, one has 1-2, one has 2—?, and the 
remainder have 1-1; in those specimens with nels loreals, the scale 
is narrowed and otherwise so shaped that it evidently is femmed by the 
fusion of two scales. The loreal is in contact with the prefrontal in 
all. Supralabials 9-10 in 1, 10-10 in 7, 10-11 in 2, 11-11 in 3. The 
anterior superciliary is present in all, and in all but 1 this scale com- 
pletely separates the preocular from the anterior supraocular. In
