CommentOriginal description (from COPE 1886): Rhadinaea quinquelineata is nearest the R. taeniata Peters, but has a much shorter tall, and differs in coloration. The scales are in seventeen longitudinal rows, and as in other species of Rhadinaea, are poreless. There is but one preocularplate,which does not approach the frontal. The loreal is longer than high; postoculars 2; temporals 1-2. Superior labials, eight, all higher than long, excepting the last, which is as high as long; the third, fourth and fifth entering the orbit. Parietal plates elongate, exceeding the frontal. Anterior border of frontal angulate, its length about equal to the lateral border. Inferior labials ten, the pregeneials considerably shorter than the postgeneials. Gastrosteges 179; anal 1-1; urosteges 77. Total length M..438; of tail, .115 ; to canthus oris .011.
Color light brown above; below to ends of gastrosteges, and upper lip, yellow. A black band runs along the middle of the fourth row of scales, and a dusky one on the adjacent halves of the seventh and eighth rows. A narrow black line along the median row. The lateral band extends through the eye to the end of the muzzle, crossing the tops of the 8th, 7th, 6th and 5th labials, becoming darker anteriorly. The band of ground-color above it extends to the eye, narrowingin front. The three dorsal bands unite into a wide brown one on the nape, which spreads out, and covers the top of the head. The last two maxillary teeth are much stronger than the others.
