Art. VI.] Herrick-Terry-Herrick, New Mexico Lizards. 143 
Boulenger says this species extends as far east as Texas and 
also describes G. kingii from Doming in southern New Mexico. 
The latter is regarded by Dr. Gunther as a variety of G. cceru- 
leus. The following description is taken from Van Denburgh 
in part. 
Gerrhonotus Scincicaudata, Skilton. 
Description: Body long and rather slender, with short limbs 
and very long tail; head pointed, with flattened top and nearly 
vertical side, temporal region often swollen in old specimens; 
rostral plate rounded in upper outline, preceded by a pair of 
small internasals, a pair of small frontonasals, very large azy- 
gous prefrontal, a pair of large prefrontals, a long frontal, a 
pair of frontoparietals, two parietals separated by an interpari- 
etal, a pair of occipitals, and (usually) a single interoccipital; 
two series (of 5 and 3) supraocculars and a series of small super- 
ciliaries. Upper labials much rarge than lower, below the latter 
two series of large sublabial plates, lower larger; gular scales 
smooth and imbricate; scales on the upper surfaces large rhom- 
boidal, strongly keeled, arranged in longitudinal and transverse 
series; about 14 longitudinal series of dorsals and number of 
transverse series to back of thighs from forty-one to fifty-two. 
A band of granules under the lateral folds; ventral plates about 
the size ot dorsals, imbricate, smooth, the grayish or brownish 
color of the back crossed by from nine to sixteen continuous 
irregular dark bands; lower parts white or yellowish with brown- 
ish or grayish suffusions. 
G. knightii is said to differ in having only six or eight of 
the dorsal series of scales keeled. It will require further study 
to determine the value of this distinction. 
(Family. Anniellidae.) 
The student should be alert for the discovery of subterra- 
nean species of this family which, so far as now known, is con- 
fined to Calitornia. The body is cylindrical and snake-like and 
the external limbs are absent.
