REPTILIA. 



Heterodon simus Linn. Pekin (H. Garman, '92). The hog-nose 

 snake is common in the Illinois valley sand region, particularly 

 under boards along sandy roads at the Devil's Neck, and 

 under stones and driftwood along the sandy shores. 



Cnemidophorus sexlineatus Linn. H.l, Je. 7. Henry, in a dry 

 sunny field on the banks of the Illinois River, not rare; 

 Ottawa; lives in dry sandy regions (H. Garman, '92). 



Terrapene Carolina Linn. (Cistudo). About ten years ago I saw a 

 number of these box-turtles traveling about the dunes of the 

 Devil's Hole, but only one was seen by us during the field work 

 for this article. The sinuous line at the edge of a moving 

 dune, shown in PI. XII., Fig. 2, was probably made by this 

 box-turtle. Southern Illinois, dry woods (H. Garman, "92).
