AMEIVA SEX-LINEATA. JU 



The anterior extremities are well developed, rounded, covered above at the 

 shoulder with a double row of large scales, and with a single row still larger at 

 the fore-arm; their inferior surface is granulated. There are five fingers, distinct, 

 scaled to the root of the nails, which are five in number, short, small, dehcate, 

 and curved. 



The posterior extremities are twice the size of the anterior; the thigh above is 

 covered with granulations, and below with a row of large scales; the leg is covered 

 like the thigh, but there are two rows of still larger scales; the tarsus is granu- 

 lated on its inferior surface, and has two rows of scales on its superior. There 

 are five distinct, delicate toes, the fourth very long, each armed with short, small, 

 curved nails; there is a range of femoral pores under the thigh. 



Colour. The head is dusky brown; the upper jaw bluish-white, the lower 

 nearly of a silver-white colour. Along the back extends, from the occiput to the 

 tail, a purple or brownish band, on each side of which are three yellow or golden 

 longitudinal lines; of these, the superior is the palest and shortest; it begins at 

 the occiput and terminates at the tail; the other lines are much longer and 

 brighter, the upper one beginning above the orbit and extending to the middle of 

 the tail; the lower line begins below the eye, and runs above the tympanum, along 

 the flanks to the anterior part of the thigh; a shorter and more indistinct line 

 extends from the angle of the mouth, below the tympanum, to the shoulder; the 

 spaces between these longitudinal bands are jet black. The throat is silver-white, 

 and the abdomen of a beautiful shining bluish-white colour.

The upper surface of the tail is nearly similar in colour to the back, but 

 appears much rougher from the verticillated scales; its inferior surface is whitish. 

 There are two longitudinal lines on each side of the tail; the superior one is 

 continuous with the central yellow longitudinal fine of the back, and terminates 

 about the middle of the tail; the inferior line is paler, it begins back of the thigh, 

 runs nearly to the extremity of the tail, and seems to divide the upper or darker 

 portion from the inferior or whiter part.
