Griffin: South American Lizards. 317 



shields under the tail. Twenty-nine scales around the middle of the 

 body. Four posterior pre-anal scales, much longer than wide, pre- 

 ceded by two large anterior pre-anals. Limbs covered by large scales, 

 except on the posterior surfaces of the thighs and shanks, which are 

 covered with granular scales. No femoral pores are visible on the 

 type, which is a female. 



The color of the dorsal surface and sides of the head, body, and tail 

 is dark brown; the scales are finely spotted and often tipped with 

 brown. A row of small black spots on each side of the back, from the 

 occiput to the tail. Just back of the ear is an oblique white bar, mar- 

 gined with black; back of this a row of white, black-edged ocelli extends 

 to the base of the hind limb; there is an ocellus on the front of the 

 shoulder, one above and in front of, and another close behind the hip- 

 joint; a row of small, white, black-margined spots on the upper surface, 

 and a row of similar but larger spots on the posterior surface of the 

 thigh. The scales of the anterior and upper surfaces of the limbs are 

 finely dotted and margined with brown. The middle of the dorsal 

 surface of the tail and a narrow line along the center of each side are 

 slightly darker than the remainder of these surfaces; it is quite probable 

 that these lines may be more strongly marked in other individuals of 

 the species. The upper and lower labials are white, except where 

 crossed by four vertical, black bars, one on the rostral and mental, 

 one half-way between the tip of the snout and the eye, one under the 

 eye, the last just back of the eye. The cheeks are black, with a white 

 spot between the eye and the ear; the anterior margin of the ear-open- 

 ing is white. 



Type, CM. No. 981, 9 , secured in the Provincia del Sara, Bolivia, 

 at an elevation of 400 meters, in September, 191 1, by Jose Steinbach. 



The species is named in honor of Professor Carl H. Eigenmann.
