. Annual report of the Board of Regents of the Smithsonian Institution. Smithsonian Institution; Smithsonian Institution. Archives; Discoveries in science. Fig. 138. ANNIELLA PULCHRA GRAY. X3. Cat. No. 16022, Body depressed cylindric >tail obtuse, about one-half as long as body, but varying somewhat in length. Scales smooth, everywhere equal, in generally thirty rows, but sometimes in twenty-eight and even twenty- six. Head but little wider than body posteriorly, contracting radially to an obtuse, moderately depressed muzzle, which projects beyond the lower jaw. Preanal scales generally larger than those which precede them, but not much. Rostral plate bounded posteriorly chiefly by the nasals, but also at the apex by the internasoloreal line, which have a short common suture on the middle line. Posterior to these there is a frontonasal, which is wider than long. Posterior to this is a large plate, probably composed of the fused frontal and frontoparietals. This is notched on the pos- terior border for a small interparietal. Posterior to these plates is a series of five smaller ones, of which two laterals on each side may be regarded as parietals, and the median an occipital. Posterior to these a few scales are larger than those of the body generally. There are six superior labials, of which the first is beneath the nasal and part of the rostral, and is very narrow. The second is the largest and is longer than high, and is bounded above by the loreointernasal and the first and second preoculars. The third, fourth, and fifth labials are higher than long, and the third and fourth reach the eye, unless cut off entirely (which it is always in great part) by the inferior preocular. Nasal triangular with the apex posterior, deeper than long. Nostril rela-.
