Sceloporus grammicus, Wiegm. Isis, 1828, p. 370; and Herpet. Mex. p- 51; Bocourt, Miss. Se. 
Mex., Rept. p. 192, t. 18 bis. figg. 12, 12 a, 5; Cope, Proc. Am. Phil. Soc, 1885, p. 397 ; 
Boul. Cat. Liz. ii. p. 231. 
Sceloporus heterurus, Cope, Proc. Ac. N. Se. Phil. xviii. p- 822. 
Hab. Mexico, Oaxaca (Bocourt), Mirador ( Sartorius), Tehuantepec (Sumichrast) ; 
GUATEMALA (Godman). 
Thirty-seven or thirty-eight scales in a series along the back; scales on the back in 
oblique series, which converge towards the median line, keeled. All the supraoculars 
of rather small size. Hind limb nearly as long as the distance of the vent from the 
collar; fourth toe rather longer than the head. Femoral pores fourteen. Brownish, 
with transverse black spots; a narrow black band across the nape, interrupted in the 
middle. Male blue on the sides of the abdomen, the blue patch being bordered 
with black interiorly. 
Of this race I have seen two young specimens only from Guatemala. 
This race is very imperfectly known, and there is great risk of confounding it with 
others. From Bocourt’s statement as to differences in the size of the scales in the 
two typical specimens, it would appear to be not improbable that the specific term gram- 
micus should be applied to one of them only. Sceloporus dugestt (Bocourt, J. c. p. 188, 
t. 18. fig. 7; Cope, 2. ¢. p. 396; Boul. Cat. Liz. ii. p. 224) = Sceloporus intermedius 
(Duges, La Naturaleza, iv. 1876, p. 29, t. 1. figs. 21-32), from Colima (Bocourt) and 
Guanajuato (Dugés), comes evidently very close to S. grammicus, but is described as 
having larger dorsal scales, viz. only nine in the length of the shielded part of the head, 
whilst in S. grammicus twelve or thirteen would be included in that measurement, 
17. Sceloporus gratiosus. 
Sceloporus graciosus, Baird & Gir. Proc. Ac. N. Sc. Phil. vi. p. 69; and in Stansb. Exped. Gr, Salt 
Lake, p. 346, t. 5. figg. 1-3; Cope, Proc. Am. Phil. Soc. 1885, pp. 379, 397. 
Sceloporus gratiosus, Boul. Cat. Liz. ii. p 230. 
Hab. Noxtu America, Utah, South-western States —Mexico, Matamoros Izucar (Ferrari- 
Perez), Putla (Boucard), Jalapa (Ferrari-Perez). 
Forty-five scales in a series along the middle of the back. Dorsal scales keeled, in 
parallel series. Supraocular series divided, the inner being composed of the larger 
scutes. Length of the hind limb less than the distance between vent and collar; 
fourth toe longer than the head. From sixteen to eighteen femoral pores. Light 
brownish above, with two light longitudinal bands on each side, a row of darker 
spots on each side of the median dorsal line. Male with a blue black-edged patch 
on each side of the abdomen. 
An adult female is 13 inch long without tail.
