Ameiva sexscutata, Giinth. Proc. Zool. Soc. 1860, p. 234 (nee Giinth.

Holeosus bridgesit, Cope, Proc. ‘Ae, Ehilad, 1868, p. 306. 
Nostril between the two nasals; upper head-shields numerous, 
strongly keeled, arranged somewhat as in some Anoles; three or 
four longitudinal rows of small shields on the interorbital region : 
occipitals numerous, very small, irregular; supraoculars two, bor- 
dered by granules, except the anterior internally ; five supraciliaries, 
second very long; a second smal] loreal, or frenoorbital; seven or 
elght upper labials ; five lower labials, third longest; chin-shields, 
one anterior and four or five pairs; no strongly enlarged gular 
scales, the granules of that region slightly keeled ; mesoptychium 
with numerous slightly enlarged scales, which are a little larger 
than the median gulars. Dorsa] granules minute, distinctly kecled. 
Ventral plates in six longitudinal series; twenty-five transverse 
series, counting from the granules of the collar. Three large, 
rounded aual plates, anterior largest, arranged in a triangle. Bra- 
chial plates small, irregular ; a row of large antebrachials : one or 
two rows of postbrachials. Three rows of large femoral plates, 
those of the median row smallest ; two rows of large tibial plates. 
Femoral pores twenty-three or twenty-four. Digits strongly ser- 
rated, Caudal scales keeled, very strongly above and on the sides, 
Greenish-olive ; a black band along each side, beginning at the end 
of the snout and passing through the eye, bordered above and below 
by a more or less marked light streak ; sometimes a light vertebral 
streak.
