Scales of collar large, in few rows, the largest at the border, larger than the 

 median gular scales. Scales of body minute, .083 mm. in diameter. Large gular 

 scales with abrupt posterior border extending entirely across throat. Four supra- 

 orbitals. Frontoparietals large as parietals, truncate in front. Interparietals nar- 

 rower than parietal, parallelogrammic. Labial scales five to below orbit; infralabials 

 five or six, the anterior pair in contact throughout. Brachial scales in six to eight 

 rows ; antibrachials in three ; femorals in from six to eight. Femoral pores 15-17. 

 Anal plates three large ones ; two posterior, one anterior. Longest toe of extended 

 hind leg reaching to meatus auditorius. 



The young have six longitudinal light stripes on a dai'k ground, which persist in 

 adults; the dark interspaces being never marked by light spaces as in the C. 

 gularis. The limbs are pale spotted on a darker ground and there is a longitudinal 

 light stripe on the posterior face of the femur. 



This is one of the smallest species, and it retains the young coloration every- 

 where. It is also distinguished by its short and high muzzle, and the absence of 

 postantebrachial scales. It covers the Austroriparian region of the Nearctic realm 

 and the eastern as far as the range of the Carolinian district, extending to Maryland 

 and Delaware, but not ^NTew Jersey. In the Central region it reaches north to the 

 Sand Hills of the Loup Fork river of Nebraska. Its southwest limit is in Texas. 



Two specimens from Florida (one of them from Key West, I^o. 15,836) display 

 the anomaly of a fusion of the three large anal plates into one. All other Florida 

 specimens are normal.
