GERRHOSAURUS FLAVIGULARIS. 



manner as the fore legs; feet and toes yellowish brown. Under parts and 

 inner surface of extremities livid cream-yellow, and the sides of the belly are 

 marked with an irregular row of pale purplish brown spots ; upper and 

 under lips yellow, dotted with umber brown ; chin and throat pale yellow. 

 Eyes reddish brown. 



Form, &c. — Figure fusiform and the tail tapered to a fine point. Head 

 small and tapered anteriorly, the nose obtusely pointed. Body somewhat 

 quadrangular, the angles rounded and the back and sides slightly convex. 

 Tail towards base quadrangular, towards point cylindrical. Frontal plate 

 five sided, anteriorly triangular ; vertibral plates four, the two middle ones 

 the largest and all externally edged with a row of oblong narrow plates 

 which form the upper margin of the orbit. Fronto-nasal plate large and 

 diamond-shaped ; the inner and hinder parts of the fronto-parietal and the 

 anterior and inner parts of the parietal plates separated from each other by 

 the intervention of a small diamond-shaped occipital plate. Temporal plates 

 small, many-sided, and generally seven in number, — one in the centre, and 

 six surrounding it. Labial scales six on upper jaw, and four on ower ; the 

 fourth scale of the upper the longest, and situated directly below the 

 eye. Meatus auditorkis extemus narrow, vertical and in front partly con- 

 cealed by a triangular or somewhat semicircular scale, which extends 

 outwards and backwards from the hinder edge of temple. Lateral duplica- 

 ture of skin moderately developed. Scales of body and tail quadrangular 

 and arranged in transverse rows, each scale with a central carina. Mental 

 plates four, the two hinder ones the largest ; the throat and breast covered 

 with somewhat six-sided scales, in shape like two triangles joined at their 

 bases. These scales are arranged in longitudinal rows, are slightly imbricate 

 and larger on the breast than the throat. Plates of the belly disposed in 

 transverse rows ten in each, of a quadragular form and perfectly smooth. 

 Preanal plates three in a single row, the middle one of a diamond-shape 

 excepting that anteriorly it is truncate. Scales covering the under surface 

 of tail at base quadrangular and smooth, towards tip triangular with then- 

 apex rounded. The fore legs are coated with smooth subovate and imbri- 

 cated scales ; the hinder ones anteriorly and inferiorly with large somewhat 

 six-sided scales ; posteriorly with small triangular and carinated scales. 

 Femoral pores fifteen or sixteen, and protrude but very little beyond the 

 scales lying anterior to them. Soles of the feet coated with small subgra- 

 nular scales.
