Hahitat and habits. — Apparently nothing is known about this 

 subject, 



Affiiiities. — As a species of Cnemldophorus, the Brazilian race 

 runner is evidently most closely related to the geographically ad- 

 jacent hnmiscatus. It is very well differentiated from that form, 

 however, having from 7 to 12 femoral pores instead of from 15 to 29, 

 a smaller size, no preanal spurs, and a different coloration. It is like 

 lemniscatus in the cephalic scutellation, with the exception that the 

 supraocular granules usually extend much farther forward. It also 

 agrees with lemniscatus in the character of the tongue, in the number 

 of ventral plates, in the keeling of the subcaudals, and in the position 

 of the nasal opening.
