There are twenty specimens in the collection, all of which are presumed to 

 have come from Colombia, and to have been collected by Mr. and Mrs. H. H. Smith, 

 except one (No. 29) which was taken by Jose Steinbach at Las Juntas, Bolivia. 

 Nos. 176-183 inc., and No. 186 are from Bonda, where they were captured by the 

 Smiths in 1901 at dates ranging from May to September. Nos. 202-203 were 

 taken by the same parties at Valparaiso, Colombia (elev. 4,500 ft.); Nos. 2006, 

 2009, and 2020 at Cacagualito, Colombia (elev., 1,500 ft.) by Mrs. H. H. Smith. 

 Nos. 1866-1868 inclusive, and Nos. 1872-1873 are a part of a collection, which, as 

 stated in the introductory pages of this paper, had no field data attached to it, but 

 are known to have been sent in by Mr. H. H. Smith while laboring in Colombia. 



Both anterior and posterior temporals are frequently divided into two or three 

 scales in longitudinal series. 



Nos. 202 and 203 are young specimens of the variety rappii. The prevailing 

 color of the upper surface is dark brown. Numerous white bars cross the back, 

 alternating with a series of shorter white bars on each side which reach the ventral 

 surface. The labials are black-margined; the chin and throat are checkered with 

 black and white. No. 2006 is uniform olive-green above, shading to brown on the 

 tail; the lower surface is white, with faint cloudy markings on the chin and throat. 

 No. 2020 is brown above, with faintly defined darker stripes along the middle of 

 the back and each side. The vertebral band is outlined by a black line in the 

 posterior part of the body. The lateral stripes become darker and more distinct 

 on the tail.
