REPORT OF NATIONAL MUSEUM, WJH. 



margin of tbe jaw. Postocular and parietal similar, transversally elon- 

 gated, the parietal somewhat larger. Four shield-shaped scales in a 

 longitudinal series between the i)arietals, postoculars, eye shield, nasals 

 on eacli side, and the rostral in front, occupy the i)lace of the vertical. 



On the crown, and just above the eye 

 shield, is a small semilunar plate, sepa 

 rating it from the series just described, 

 thehomologueof the supraorbital. The 

 margin of the upper jaw is formed in 

 front by the rostral ; on the sides next 

 to the rostral by the nasal, behind which 

 is a subquadrangular, obliquely ele- 

 vated labial, limited above by the fronto- 

 nasal, and posteriorly by the eye shiekl, 

 which enters likewise in the upper labial 

 series. Posterior to the eye shield is a 

 subtriangular labial at the angle of the 

 jaw, approximating above the postocu- 

 lar, and limited behind by the parietal 

 and the beginning of the scales. Inferior labials five, similar to the 

 scales under the throat. 



The scales present a great uniformity throughout the whole length 

 of the body; a little smaller beneath than above. 



This species ranges from central Texas to the Red River on the east 

 and southward along the Rio Grande in Texas as far as San Antonio.
