DiagnosisDiagnosis: A form of Agamodon with the two azygous head shields forming a faintly concave, keratinized surface, with projecting lateral edges, that occupy most of the anterior aspect when the animal is at rest. The mental and post­ mental segments are slightly raised. The cross section of the trunk is subtriangu- lar, with dorsal surface rounded, the sides sloping outward and the wide ventral surface with a deep smooth midventral groove. The segments of the dorsal and ventral surfaces are rounded or imbricated by the diagonal overlap of the inter­ secting continuations of the lateral sections of the annuli. The tail is slightly compressed and rapidly reduces in size to a pointed tip. Specimens have 124 to 138 body annuli; 10 to 16 caudal annuli; 42 to 55 segments to a midbody annulus, and generally 4 (range 0 to 6) precloacal pores.

Color in life : generally bright yellow dorsally, blotched with brown saddles and dots of varying sizes and shapes, bright pink ventrally. A very few specimens lack the brown; one lacked all dorsal pigmentation. In preservative the color fades to white with brown markings.
 
CommentType species: Agamodon anguliceps is the type species of the genus Agamodon PETERS 1882. 
EtymologyFrom “agama” and odon (Greek) = tooth; the teeth are acrodont like the agamid lizard's teeth; that means they are set on the top of the jaw bone and not on the side, which is known as pleurodont; angulus (Latin) = angle, a corner; ceps, from caput (Latin) = head; a reference to the chisel-shaped head.
