those of the upper and inferior surflices. Along the upper surface of 

 the neck they are larger than on the back and tail, whilst they are a 

 good deal smaller on the sides and inferior surftice of the same region 

 than on the sides of the body and on the abdomen. The scales are 

 quite small upon the pectoral fold. 



The black and yellow are the only two colors observed. Upon 

 the upper surface and sides of the head the black predominates as 

 ground color, over which are six interrupted and transverse yellow 

 bars : two across the fronto-nasal region, two upon the interocular 

 space, and two on the occiput. Upon the neck and shoulders the 

 yellow appears as ground color, and the black constitutes narrow, 

 black, and lunate bands, convex backwards, stretching obliquely for- 

 wards and downwards on the sides. The intervening space between 

 these black bands is spotted with black, and along the middle region 

 of the neck the black spots occupy as much ground as the yellow itself. 

 The upper surface of the body and limbs is black, with semi-annular 

 bands of yellow spots and dots. Beneath, the predominating hue is the 

 yellow. Six or seven jet black transverse bands may be observed from 

 the extremity of the lower jaw to the pectoral fold, and two narrower, 

 though longer ones, across the chest. Along the abdomen they are 

 proportionally more numerous and less regular, though nearly equal 

 to the yellow intervals, and under the legs they are undulated or 

 waving, and narrower compared to the yellow intervals. The yellow 

 intervals under the abdomen are spotted with black, and the black 

 bands spotted with yellow. The tail is similarly annulated and 

 spotted.

Tam. LACERTIDAE. 



According to recent writers on herpetology, the Saurian family here 

 referred to may be characterized by a quite elongated and rounded, 

 neither depressed nor compressed, body; the tail being especially elon- 

 gated, reaching, in some species, a length four times that of the body 

 itself. Four strongly developed limbs, provided with four or five fingers 

 and five toes, rounded, or slightly compressed, slender, conical, unequal,
