MEXICAN HERPETOLOGICAL MISCELLANY—SMITH 373 
Color.—Head gray-brown, with a few darker brown flecks, and 
some of the scales edged with dark brown; sides of body and neck 
darker brown, with numerous, somewhat irregular, vertical light bars 
a little over a scale wide, and separated from each other by the width 
of from two to three scales; dorsal surface gray-brown as head, with 
small dark flecks scattered on many of the median scales; scales just 
above the dark sides with very few flecks; tail a little lighter than 
body, with longitudinal flecks of brown on the centers of the scales, 
particularly prominent on the two median scale rows. Ventral sur- 
faces of body and tail bluish, except for the preanal region, a narrow 
area across chest, posteroventral surfaces of limbs, and midventral 
surface of tail, which are white. 
Variation—The adult paratype (U.S.N.M. No. 62992) is marked 
like the holotype. The juvenile from Piedras Negras, however, which 
measures 44 mm. snout to vent, is somewhat different. The sides of 
the body are dark and with vertical light bars as in the adults; the 
light bars are not quite so broad and a little more broken into spots; 
they extend somewhat into the dorsal region. A very broad, black 
band extends from the snout along the middle of the back onto the 
base of the tail; it covers three and two half-scale rows on the middle 
of the back, and on the head involves nearly all of the prefrontal 
and parietals. This band is separated from the lateral band by a 
broad light line extending from snout through the lateral supraocular 
region to the tail; these cover two and two half-scale rows at the 
middle of the body, and are greenish in the temporal region, cream 
on snout, and of a golden tint over most of the body. The lateral 
light streaks are very pale blue. Ventral surface of body rather bright 
blue, hghter on chin and on limbs. 
There is but little variation in scutellation. In 1 the anterior super- 
ciliary is narrowly in contact with prefrontal on one side; the occipital 
and interparietal are half the size of the parietals in 1; median loreal 
fused with scale above it on one side in 1, but the distance between the 
anterior and posterior loreals still greater than the length of either; 
7-8 superciliaries in 1; 7-8 supralabials to below middle of eye in J, 
8-9 in other (8-9, 9-10, respectively, to posterior border of subocular) ; 
scale rows 31 in 1 (No. 113527), 33 in other; lamellae under fourth 
toe 23-23, 26—% 
FRemarks—The holotype was discovered during the day by my 
wife, for whom it is named. It was rapidly running up the trunk of 
a small tree near an open spot in a wooded area. 
The species differs from enneagrammus chiefly in the elongate, 
flattened snout and different pattern. The lengthening of the snout 
is expressed in the larger size of the medial loreal, the elongation of 
the nasal, and the enlargement of the rostral.
