 as well, markings entirely absent in the present species. In 

 fiaviventer- the ventral surface of the tail is distinctly darker

 uniformly colored above and below. 



There are no measurements with the single adult example of 

 ochracea, but the skin indicates an animal smaller than flavi- 

 venter. The young individual (about half grown) is practically

 including the whole back, as well as the sides of the neck.
