Cope. ] 94 [July 20, 
Several rows of large scales on the collar, the border row not larger nor 
much smaller; two preoculars and a frenoédcular ; larger gulars median, 
three supraorbitals ; postbrachials small; brachials in 3, femorals in ten 
rows; adult with eight longitudinal bands; femora pale spotted. 
The small size of the postbrachial and femoral scales, relate this species 
to the C. guttatus, but it lacks the small scales of the border of the fold seen 
in that lizard. The interparietal in an adult is narrow. The temporal re- 
gion is covered with minute scales. There are numerous small scuta be- 
hind the parietals. There are two rows of antebrachial scuta well defined 
at the borders. Two rows between the inferior and infralabials. The in- 
ferior lateral brown band extends to the orbit. Throat pale ; breast plum- 
beous.

CNEMIDOPHORUS LINEATTISSIMUS Cope 
This swift lizard is of medium size in the genus, and maintains the lined 
coloration intact. 
Several rows of large scales on the collar, the border row not larger nor 
much smaller ; two preoculars ; no frenodcular ; three supraorbitals ; larger 
gulars extending across throat ; superior preocular not descending to la- 
bials ; postbrachials large, continuous with brachials; femorals in eight 
rows ; black, with ten or eleven pale bands ; sides and femora pale spotted ; 
throat black. 
The muzzle is rather acute but not elongate, and the fronto-nasals have 
considerable mutual contact. The larger and smaller gulars are abruptly 
distinguished from each other, and the former are smaller than the scales 
of the collar. The frenal plates form a circle surrounding a large median 
scute, of which the two posterior plates are the largest. 
There is a space between the two submedian lines, which is often divided 
by a median line. Below the lowest line the sides are black with large 
light spots, open below.

CNEMIDOPHORUS LATIVITTIS Cope. 
Several rows of large scales on the collar, the border row not larger nor 
much smaller ; two preoculars, the superior not descending ; no frenoor- 
bital ; supraorbitals 3; larger gulars extending across the throat; post 
brachials large, continuous; femorals 8 rows; olive, with eight wide 
bands, ground black between second and third 
The nostril is in front of the nasofrenal suture. Parietals and interparie- 
tals of normal proportions, surrounded by a series of moderate scales, in 
a semicircle. One row between the inferior labials and infralabials. Brach- 
ials large, in five continuous rows, distinct, no postbrachials. Two 
rows of antebrachials. Scales of collar equal those of gular region, larger 
than postgulars, and smaller than abdominals. Femoral pores seventeen. 
Color below bluish; pectoral region blackish ; there are small yellow
