AMPHIBIANS AND REPTILES OF SINALOA, MEXICO 143
in contact; superciliaries 7-8; supralabials ?-7; infralabials 7-7; 28
scale rows at midbody; snout-vent 49; adpressed limbs overlap
lengths of digits. The dorsolateral light stripes, visible only on the
head and neck, are less than one scale wide and are separated by
four complete scale rows on the neck.
A single specimen was obtained beneath banana leaves at La Cruz
on July 4, The leaves were piled beneath the trees and were in
an advanced state of decay. Four skulks were uncovered but only
one was collected. Two lizards had bright blue tails in life. Two
clutches of eggs (six eggs in each) were found in separate depressions
in moist soil beneath the leaves. In both instances the lizards were
coiled around the eggs and only when attempts were made at capture
did the lizards leave. Two other specimens, both juveniles,
were collected in dry palm leaves near Teacapan. Zweifel (1962:64)
reported a specimen found during bulldozing operations near
Mazatlan in January.
Distribution in Sinaloa.—Throughout the lowlands below about
600 meters. See Fig. 54.
Specimens examined.—16 km. NNE Choix, 520 m. (" KU 73745); La Cruz
(LACM 6768); Teacapan (LACM 6769-70).
Literature records.—5 mi. N Mazatlan (Zweifel, 1962:64); Presidio (Boulenger,
1883:342; Taylor, 1936c:363).
Eumeces colimensis Taylor
Eumeces colimensis Taylor, Field Mus. Nat. Hist., Zool. Ser., 20:77, May 15,
1935 (type locality, Colima, Colima).
Remarks.—Taylor (1935a: 77-80) described Eumeces colimensis
from one specimen having no primary temporal and the frontal
and interparietal in contact, Taylor (p. 80) remarked that only
additional collecting would determine if the temporal and frontalinterparietal
conditions are normal. Since Taylor's description three
additional specimens have become available. Two specimens from
Michoacan were reported by Peters (1954:16-17); one specimen
from Sinaloa was reported by Webb (1959:42).
Data from all known specimens reveal that the type is unique
in the characters of the frontal-interparietal contact, absence of
the primary temporal, and in that the adpressed limbs overlap the
length of the foot. The prefrontals are in contact in two specimens
and separated in two (KU 44733 and holotype). The type has 6
superciliaries (Taylor, 1933a:78), but as pointed out by Peters
(1954:16-17) the illustration of the type (fig. 7) shows seven.
Taylor (1936c: 71, fig. 4, A, D) defined the superciliaries of the
