above the vent is 58 and 60, and the number of dorsal scales in a 

 head-length is 14 and 15. While the medial series of scales on the 

 snout is continuous in the type, it is discontinuous in one of the para- 

 types. The other paratype has an old injury on the snout in this 

 region. 



"In coloration the same essential features are present in all three 

 specimens. One of the paratypes is much more brightly colored than 

 the type, however, and has some brilliant pale green scales edging 

 the darker cross-bars over the neck, and likewise accenting the lower 

 edge of the dark lateral stripe. Below this the sides appear purplish 

 brown, with the occasional bright blue scales mingled there." 



In addition to the original specimens on which the description of 

 the species was based, three others have since come under my obser- 

 vation. These are very similar indeed to the type and paratypes. 

 The supraoculars are six in all cases, and the prefrontals two in number. 

 There are 44 or 45 scales around the body, 15 or 16 in a head length, 

 and 58 to 60 along the back from occiput to base of tail. On two of 

 them a distinct light lateral stripe may be found that originates behind 

 the last supraocular and passes backward above the brown lateral 

 stripe onto the tail. The indications of cross bands in the nuchal 

 region are present in aU the specimens, and down the back there are 

 fairly regular markings that may be the remainder of a fuU set of 

 cross bars, which the young probably possesses. So far none but 

 fully adult specimens have been collected, but it is safe to say that 

 this is one of the species in which the juvenile pattern is far more 

 pronounced and brilliantly contrasted than the subdued and darkened 

 tone of the adults. 



The postanal scales are very poorly differentiated from the scales 

 that surround them, and for this reason it is exceedingly hard to tell 

 the sex from exterior inspection alone.
