Aside from the specimens reported by Peters (1954:17), one other
specimen was obtained at El Ticuiz. It has 22 scale rows, 3 supraoculars
in contact with the frontal, 2 postlabials, and a unicolored olive-tan
dorsum. In life the anterior dorsolateral stripes were pale pinkish tan,
the labials cream color, the throat white, and the tail pale blue. All
specimens were found in semi-deciduous broad-leaf forest at elevations
of less than 500 meters on the seaward slopes of the Sierra de
Coalcoman.

Six males and six females from the Tepalcatepec Valley have more femoral
pores than do 16 males and nine females from the coastal lowlands; the
ranges and average number of femoral pores in the former are 40-50
(44.8) for males and 38-40 (38.6) for females; males from the coast have
34-44 (39.2), and females have 32-40 (36.2) femoral pores. In all
specimens the number of lamellae beneath the fourth toe varies from 26
to 33 (29.7). In life juveniles have a pale olive-tan dorsum and a
dorsolateral dark band, superimposed on which is a row of darker brown
spots. The dorsolateral band is bordered below by a narrow cream-colored
stripe. The tail is tan above and grayish white below; the belly is pale
bluish white. Adult males are brilliantly colored in life. A male having
a snout-vent length of 108 mm. had a rusty brown dorsum and bright blue
bars on the flanks separated by dark brown interspaces. The side of the
head was pale green, and the chin and throat were golden yellow. In some
specimens the throat is orange. Juveniles and subadults have dark flecks
on the brown or tan middorsal area, but these are absent in the largest
males.

This species inhabits the heavily wooded areas in the lowlands to
elevations of about 950 meters. In the Tepalcatepec Valley it has been
found only in gallery forests along streams. In both the Tepalcatepec
Valley and the coastal lowlands there is a noticeable a
