 locality, Territory of Chubut, Argentina). 



Four large representatives of this form, U, S. Nat. Mus. Nos. 

 63954-7, taken by Alexander Wetmore on December 9, 1920, at 

 Zalapa, Gobernacion de Neuquen, Argentina, indicate that it may be 

 related to L. multiformis simonsii. The dorsal scales are very small, 

 much smaller than the lateral and ventral scutes, and distinctly, 

 though not strongly, keeled. Stripes are not present on the body 

 and, with the exception of a more or less pronounced cross-barring 

 on the tail, there is little evidence of a longitudinal arrangement in 

 the dorsal markings. The median dorsal area of the back is uni- 

 color, or nearly so, and dark brown in shade, but the lateral region 

 is light brown or gray with white spots. The flanks and under 

 surfaces are tinged with blue green, and are covered with more or 

 less indistinct slate or brownish flecks.
