CROCODILIANS, LIZARDS, AND SNAKES. 891 OSCEOLA DOLIATA SYSPILA Cope. OphiboJus dolidtiis syspilus Cope, Proc. U. S. \at. Mus., XI, 1888, p. 384. Head small, flattened above, with the snout rounded; neck slightly contracted; body elongated,rather slender; scarlet above, and jnarked with black rings, in pairs; between each pair is a white ring. The vertical plate is pentagonal, with an acute angle behind; the superior orbitals are oblong-quadrilateral, broadest behind, and not projecting over the eye; the occipitals are polygonal, and very large; the frontals are broad and pentagonal, narrowest externally, where they descend to join an elongate quadrilateral, loreal i)late. The anterior frontals are also quadrilateral, smaller than the jiosterior, and broadest externally. The rostral plate is large, heptagonal, and concave below. There are two nasal plates, the jDosterior square, the anterior lunated behind for the nostril, which does not enter the posterior, but comes out at its anterior border. There is a single anterior orbital plate, oblong, slightly concave behind, and two small, subround, posterior orbitals. The inferior wall of the orbit is made up of the third and fourth superior labial plates, of which there are Fig. 216. Osceola doliata syspila Cope. X The nostrils are lateral and near the snout. The eyes are small, the iris bright reddish gray. The neck is but slightly contracted, and is covered with small, smooth, subhexagonal scales. The body is long, tolerably stout, and covered above with scales similar to those of the neck, but larger. The tail is rather short, thick at its root, but soon becomes smaller, and terminates in a tip. The anterior top of the head is crossed with a black band at the extremities of the occipitals, and the dark color may extend as far as the prefrontal plates,
