198 MEMOIRS OF THE CARNEGIE MUSEUM 



snout, much shorter than the parietals, twice as wide as the supra-ocular; supra- 

 ocular much broader behind than in front; loreal oblong, once and a fifth to once 

 and a half as long as deep, entering the orbit; no preocular; one crescentic postocular; 

 temporals 1, 2; seven upper labials, the third and fourth entering the orbit; two 

 pairs of short chin-shields, the anterior a little the longer and as broad as long, the 

 posterior broader than long. 



Scales smooth, in 15 rows; anal entire; gastrosteges 147-157; urosteges in 44 

 to 47 pairs. 



Upper surface reddish brown, with a dorsal series of black spots narrowly 

 margined with white; the anterior three or four spots are several times as large as 

 the others and extend upon the edges of the gastrosteges. Between the first and 

 second, and the second and third spots, the interspaces are almost white (red in 

 life?). The sides of the body and tail bear smaller and more numerous black spots 

 which may reach to the edges of the gastrosteges. The scales of the lighter 

 areas are finely stippled with brown and black. 



A black fleur-de-lys-like marking on the parietals and frontals (on specimen 

 47 a nearly uniform dark rounded spot) ; lips, chin, and lower surface white (pink 

 in life ?) with black dots; most of these on specimen 42 are very small, but on 47 

 they are nearly all large square checks. The urosteges are nearly covered by black 

 checks. 



The type (C. M. No. 42) and the paratype (C. M. No. 47) were both collected 

 in the Province del Sara, Bolivia, at an elevation of 350 meters, by Mr. Jose Stein- 

 bach, the former in November, the latter in December, of the year 1912. Both 

 specimens are males.
