Color brown above, obscurely marked with black, this 

 color being mostly confined to the bases of the scales and indi- 

 cating vertical lateral bands and dorsal spots as in T. sipedon. 

 Brownish beneath posteriorly, paler anteriorly; in an Illinois 

 example yellowish below, with a small black spot on each side 

 of most of the abdominal scutes, and with a few similar irreg- 

 ularly placed spots on the under side of the tail.

Southern Illinois. Bluff Lake, Union county. 



The only example of this species in the Laboratory collec- 

 tion from Illinois differs in some respects from the typical forms 

 "of the species as described. On one side there are two subor- 

 bitals, on the other but one; on neither side is the anteorbital 

 in contact with the suborbitals; the latter crowd the labials 

 away from the eye, leaving an unoccupied space above the 

 fourth labial. The dorsal scales are in twenty-nine rows. The 

 ventrals number one hundred and forty; the subcaudals, sixty.
