Any small gray or reddishbrown snake virtually without markings may be this one. There may be an indication of a faint light stripe down the back,  and many scales may have faint light lines upon them that look like keels but aren't. Often a dark "shadow" from eye to nostril. Belly plain white or yellowish. Upper labials 6 in number; a horizontal loreal scale. Scales smooth or weekley keeled and in 15 or 17 rows. Anal plate divided.
