Anal plate entire in five specimens. 



Color uniform green, pale on the lips and throat. In a young specimen (.340 

 m.) there are slightly black edged scales in small patches on each side of a pale 

 vertebral band. 



As compared with the H. fuscus, this species has a smaller eye at all ages, and 

 a stouter form, including shorter tail. It bears the same relation to the form 

 called Dendrophis viridis, by Dumeril and Bibron.

Scales elongate, biporous, smooth, in seventeen longitudinal rows. Form 

 slender, head narrow ; the frontal shield with concave sides, much narrower 

 behind than before, and one-fourth longer than the muzzle anterior to it. Parie- 

 tals long. Postnasal higher and shorter than prenasal. Loreal long and low, 

 lowest behind. One preocular not reaching frontal, two postoculars ; temporals 

 2-2, long and narrow. Superior labials nine, fourth, fifth, and sixth, entering 

 orbit ; inferior labials ten, six in contact with geneials. Pregenials only half as 

 long as postgenials. Gastrosteges 188; anal divided; urosteges 116. Muzzle 

 shorter than interorbital, width by nearly the diameter of the eye. 



General color olivaceous-ashen ; a broad, brown, dorsal band, which is darker 



edged, extends to the tail, involving five rows of scales. A brown band on each 



side involves the first, second, and third rows of scales, which are blackish tipped. 



Lips and below lighter, unspotted ; a dark band from nostril through eye to last
