Plates of head as iii JFJ. sMltonianus. The dorsal scales of equal 

 width, or the ventral not larger. Dorsal scales 28 to 34, and about 55 

 from head to tail. Tail one and one-fourth or one and one-half tiiuGS 

 the body wlien perfect. Fore leg from elbow longer than head to ear, 

 which is contained about four or four and one-half times in head and 

 body. Hind legs, applied twice forward, reach to or a little beyond 

 the ear; contained two and one-half times or less in from knee, three to 

 three and one half times in head and body. Free portion of long hind 

 toe nearly three fourths the side of head to ear; the fifth toe decidedly 

 longer than the second. 



Coloration. 1. Black above, including the head, with five equidistant 

 narrow whitish stripes, a dorsal and two lateral; the median bifurcat- 

 ing at the occiput, the branches uniting at the rostrum. Each line 

 usually on adjacent edges of the rows of scales (occupying half or 

 third) and separated by one, sometimes two, rows of the ground color 

 ("/«sdatMs"). 



2. The rest of the scales through which the three middle stripes run, 

 black; the intervening scales light olive; the cephalic white line then 

 fainter, and next the dorsal, until the whole space between the upper 

 lateral stripes is olivaceous, with four dusky lines of dots along the 

 middle of scales, head becoming reddish and wider {^^ quinquelineatus^^).
