220 REPTILES OF MASSACHUSETTS. 



sky blue, blended with yellow and black lines, which run 

 longitudinally along the back. 



A yellow line commencing over each nostril, passes obliquely 

 backwards, and, approaching each other, they unite at the dis- 

 tance of rather more than a quarter of an inch back of their 

 origin, forming a dorsal line, which, continued the whole 

 length of the body, is lost upon the tail ; on each side of this 

 dorsal line, runs another, which arises at the superior anterior 

 angle of the eye, and terminates like the preceding ; beneath 

 this, is still another, commencing at the snout, and interrupted 

 only by the meatus of the ear, is continued like the others upon 

 the tail. These yellow lines give the back the appearance 

 of being divided into yellow and black longitudinal lines. 

 Head, half an inch long ; one quarter of an inch wide ; with 

 large plates above. Eyes, small. External meatus of the ear, 

 vertical, large. Anterior feet short, with five toes, each armed 

 with a sharp nail. Posterior extremities, large ; second toe 

 very much elongated, and all the toes, like those of the fore 

 feet, nailed. 



Extremities above, of a brown color, having a longitudinal 

 yellowish white line running along their posterior portion to 

 the toes. 



The vent is transverse, situated just back of the interior 

 of the thighs. Tail longer than the body, its posterior portion 

 a deep blue. 



The species feeds upon insects.
