Notes

This snake was unusual in that it didn't fit the textbook definition of either T. gracilis or T. atriceps. After examination of its scalation and hemipenis, I concluded it must be atriceps, but I was uncertain of its correct identification. The identification of Tantilla atriceps was confirmed by Dr. Jim Dixon.
Specimen is in the Texas Cooperative Wildlife Collection.
