the rest of the band is less evident or absent. The black 

 scales often have white or whitish tips. The markings on 

 the tail are similar to those on the body. The limbs may 

 be unicolor or marked with dark brown or black. The upper 

 surface and sides of the head are grayish or olive brown 

 with few or many blackish brown spots. There are from 

 three to five white spots along the upper jaw. The lower 

 surfaces are yellowish white, more or less clouded with gray 

 on the belly, and usually with numerous small black spots. 

 These black spots or dots may be present only on the lateral 

 ventral scales and the lower surface of the tail, or may be 

 distributed over the entire lower surface. Their arrange- 

 ment is rather irregular. They often have a tendency to 

 form lines of dots, but these may be either near the cen- 

 ters of the rows of scales or near their edges. The lateral 

 ventral scales often show transverse black bars with white 

 spots, similar to those on the lateral dorsal scales.
