as long as broad or longer, as long as, or longer than, the prefrontals; frontal once 

 and a quarter to once and a half as long as broad, shorter than its distance from the 

 rostral (this is true of the mature specimens, the frontal of small specimens is longer 

 than its distance from the end of the snout); frontal as long as, or shorter than, 

 the parietals; loreal deeper than long; one pre- and two postoculars; temporals 1,2; 

 eight upper labials, the fourth and fifth bordering the orbit; five lower labials in 

 contact with the anterior chin-shields which are as long as, or longer than, the 

 posterior. 



Scales in 19 rows: gastrosteges 160-167, obtusely angulate laterally; anal 

 divided; urosteges in 49-54 pairs. 



Uniform dark green above, this color extending to the outer ends of the gas- 

 trosteges. During life the color is undoubted^ of an olive tone, due to the color 

 of the horny scales, most of which are rubbed off in our specimens. There are no 

 spots, nor light or dark edges to scales; neither have the young a dark nuchal band. 

 The lower surface is a uniform yellowish white. The ui)per lip is light green, 

 lighter than the upper part of the head, but not white. (Type, C. M. Cat. Rept., 

 No. 32.) 



The Museum has fourteen specimens of this species, all of which were collected 

 by Mr. Jose Steinbach in the Provincia del Sara, Bolivia, and most of them bear 

 the label Santa Cruz de la Sierra. They bear in the Catalog of Reptiles of the 

 Museum the numbers 32 (type), 44, 59, and 91-102 inclusive. All after No. 32 

 are regarded as paratypes. The type has a label giving the date of capture as 

 February, 1913. No. 59 is labelled as having been taken in October, 1911. No 

 dates are given on any of the other labels.
