cal; femoral pores only two or three. Parietals large; interparietal 

 longer than broad. Frontal and frontoparietal broad; former longer, 

 undivided, l^ivided frontonasals and internasals in contact; supra- 

 orbitals in contact with both marginals and superciliary ridge, four on 

 each side. Three pairs infralabials, transverse, the anterior barely in 

 contact. Three bordering scales of car, not larger than those preced- 

 ing. End of nui/zle to ear, 2.3 mm. ; ear to vent, 80 mm. ; length of tail, 

 75 mm.; length of anterior extremity, 17 mm.; posterior, 14.7 mm.; hind 

 foot, 25 mm. Males, above brown, with a yellowish dorsolateral band 

 and seven or eight pairs of yellowish, anteriorly black-edged spots on 

 the back. Top of head red, below whitish, sides faintly blue tinged. 

 Females brown-olive, with a ])aler dorsolateral band. Throat, a broad 

 band to shoulders and sides of abdomen blue. 



This species is especially characterized by the small number of its 

 femoral pores. It differs further from the S. spinosus and agrees Avith 

 the species of the tS. clarldi group in the absence of small scales 

 between the supraoculars and frontoparietals.

Although this species abounds in the tierra caliente of the west 

 coast at Coliiua, it inhabits also the plateau of Jalisco.

 lig. 4. 



Dorsal and lateral scales large, subequal; ventral scales a little 

 smaller. Femoral pores, 13-15. Head scales smooth ; frontal not lon- 

 gitudinally divided; two parietals on each side. 



Scales rounded, not keeled, the border serrate with a moderately 

 prominent, Hat median point. Caudal scales with longer and recurved 

 points. Scales of inferior surfaces notched; those of the limbs above 

 keeled and mucronate, below little notched or entire. Dorsal scales 

 in parallel rows; of sides oblique upward and backward. Two scales 

 on the canthus rostralis. One row of transverse scales above the 

 orbit, which are separated from the frontals forward by one row of 

 small scales, but are in contact with the froutoijarietals and parie- 

 tals. Two parietals; the anterior rhomboidal, the posterior transverse.
