This species is very constant in the scale formula, preserving fif- 

 teen rows in twenty-seven specimens in which I have counted them. 

 The labials are always seven, the only exception being a specimen which 

 had met with an injury on the top of the head (Cat. No. 1495). The 

 fourth labial on the right side and the first and fifth on the left are 

 abnormally divided obb'quely. The relation of the loreal to the nasal 

 is changed in four specimens on both sides, and in one, on one side, by 

 the fusion of the two plates. In two specimens there are two preocu- 

 lars on both sides, and in one on one side only. In another (Oat. No. 434) 

 the oculars are 2-3. 



The Liopeltis vernalis has a wide range, embracing the entire Eastern, 

 Austroriparian, and Central regions. It is found in the hilly parts of 

 New Mexico, but is rare in Texas. Florida specimens are higlily col- 

 ored. It is in the North that the species especially abound, being- 

 much more common in my experience in Massachusetts than in Penn- 

 sylvania. Professor Yerrill gives it as commonly found at Norway, 

 Maine. It is absolutely harmless.
