446 4. ANGUID^ 



two parietals separated by an interparietal, and a pair of 

 occipitals with one or more interoccipitals between them. 

 Two series (of five and three) supraoculars, and one series 

 of small superciliaries. All temporal scales keeled. Upper 

 labials much larger than lower. Below latter, two series of 

 sublabial plates, interior larger. Gular scales imbricate and 

 smooth. Scales on upper surfaces and sides of neck, body, 

 and tail large, rhomboidal, slightly oblique, strongly keeled, 

 reinforced with bony plates, and arranged in both longi- 

 tudinal and transverse series. Number of longitudinal 

 series on body 1 6. Number of transverse rows between 

 interoccipital plate and backs of thighs varying from 42 to 

 49 in specimens examined. A band of granules along each 

 side from large ear-opening to anus, usually hidden by a 

 strong dermal fold. Ventral plates about size of dorsals, 

 smooth, imbricate, and arranged in twelve (or thirteen) lon- 

 gitudinal series. Number of scales from symphyseal plate 

 to anus 59 to 62. 



The ground color above is olive-brown or bluish or 

 greenish drab, usually a little paler laterally than near the 

 middle of the back. There are no definite cross-bands, the 

 dark pigments appearing in ill-defined marblings or blotches 

 on the back, or in white-tipped black spots on the sides. The 

 head and limbs are usually unicolor, but may be marked 

 with darker brown. The lower surfaces are yellowish or 

 greenish white, sometimes slightly washed with gray. There 

 are no definite longitudinal lines on the belly in the speci- 

 mens which I have seen, but two specimens have indications 

 of them between the rows of scales.
