Conejos and Costilla
counties in extreme south-central Colorado south across New
Mexico to Mexican border. Records from neighboring drainage
systems, Casas Grandes in Chihuahua and Artesia and Ocate
River in New Mexico, probably also pertain to _ornata_.

_Description._--A specimen in the University of New Mexico
Natural History Museum (E. D. Flaherty No. 560, obtained
one mile west and one-half mile south of Isleta, Bernalillo
County, New Mexico, on May 31, 1959) was described as
follows while its colors were still but little altered by
preservatives: Top of head olive, supralabials pale gray,
edged with black posteriorly; chin milky white, with dark
edges posteriorly on fifth, sixth and seventh infralabials;
dorsal stripe yellow; including middorsal row of scales and
little more than adjacent half of row on either side of it;
dorsolateral area olive-brown with row of black spots on its
lower half, these spots elliptical, averaging about size
of one scale on anterior part of body, smaller posteriorly;
adjacent spots separated by interspaces of approximately
their own length, irregular black markings on upper half
of dorsolateral area not forming definite spots but fused
longitudinally to form continuous black border to dorsal
stripe; crescent-shaped red markings in areas between scale
rows three to nine, these markings invading edges of scales,
and themselves having ill-defined edges blending into the
darker ground color; lateral stripe pale, yellowish gray,
limited to scale rows two and three for most of its length,
but including rows four and five in neck region; row of
irregular black marks low on each side, with each mark
centering on anterior part of lower half of scale of first
row but overlapping onto corners of adjacent ventrals;
approximately every other scale of first row so marked;
ventral surface pale, suffused with bluish tint; most of
ventrals marked on anterior edges with pair of semicircular
black spots, each situated about two-thirds of distance from
mid-line to lateral edge of ventral; these marks diminishing
in size and finally disappearing on posterior part of body;
ventral surface otherwise immaculate.

Lepidosis normal for genus and species, with preoculars single
on each side, supralabials 7-7, infralabials 8-8, ventrals
159, anal ent
