similar to the dorsals, but smaller ; lower sui-face with 3 or 4 series 

 of subequal shields or with one series of large and two of small sliields. 

 12 to 19* femoral pores on each side, the two series widely separated 

 in the middle. Two series of strongly keeled subdigital lamellae, 21 to 

 26 under the fourth toe.

 smooth ; 40 to 46 scales in the foui'th or fifth whorl behind the post- 

 anal granules. 



Yellowish grey, reddish brown, or orange above, with lilackish 

 markings whicli vary greatly according to individuals. Tlie three 

 principal forms liave been described and figured under diii'ereut 

 names by Strauch : 



A. "With a dark network : E. hrachyJactyla. 



B. With rather large, irregular black spots : E. Jcesslert. 



c. The black spots confluent into irregular cross-bars ; head with 

 large black spots : E. przewahkii. 



These three patterns of markings are connected by a number of inter- 

 mediate types. 



Bedriaga further describes specimens with 7 longitudinal series of 

 black and white, more or less ocellar spots, not unlike E. argus or 

 E. arguta ; these specimens may have light longitudinal streaks on 

 the naj)e and on the temple and the side of the neck, and one on the 

 side of the belly. The young specimens examined by the same author 

 are not streaked, but barred or reticulate.
