Head 3* to 3|; depth 3| to 4£; D. hi, 7, i; A. usually iii, 9, i, 

 rarely iii, 8, i or iii, 10, i; scales usually 30 or 33, seldom 32 or 34. 

 rarely 28, 31 or 35 + usually 2, frequently 3; usually 6 scales above 

 1. 1., rarely 7; 4 scales below 1. 1. ; usually 14 predorsal scales, often

 illary 24 to 2|; interorbital 2| to 3£; teeth usually 1, 4-4, 1, rarely 

 1, 5-4, 1; length 2M to 3ts inches. Cotypes of P. pyrrhomelas 95 

 (type No. 2,631, A. N. S. P.). Cope says the teeth are without 

 masticatory surface, which is not in agreement with my examination 

 of his material, as they have well-developed grinding-surfaces. He 

 further disagrees in stating ventrals reach the anal.
