|Diagnosis||DIAGNOSIS: A form ofAmphisbaena with the mental and postmental fused; with the nasals the largest segments on the head [and the frontals scarcely distinguished; with the oculars split to form triangular infraoculars equal in size to the oculars]; and three supralabials and two infralabials. The form has 247  body annuli; nine caudal annuli up to the autotomy constriction (at which the tail is autotomized); 17 to 18  dorsal and 16  ventral segments to a midbody annulus; and six precloacal pores. The color of preserved specimens is yelowish,with an irregular dorsal scatering of individual dark segments [the frequency of dark segments is suficiently high on the midbody dorsal surface to yield the impression of a scatering of light segments on a dark background], thinning out anteriorly toward an immaculate head.The anterior half of some [most] infracaudal segments is strongly pigmented, while the infracaudal segments of the ninth postcloacal annulus are entirely pigmented (Gans 1963: 5)|
