| Diagnosis | Diagnosis. Maxillary teeth modified; third and fourth supralabials entering orbit; preocular present; mental touching anterior chin shields; paraparietal surrounded by 5 shields and scales; eye about 2/3 eye-mouth distance; dorsal scales without network (Inger & Marx 1965). Description. Rostral wider than high, portion visible from above equals half length of prefrontal suture; prefrontal equals length of frontal, touching first 2 supralabials; frontal hexagonal, 2.5 to 3 times width of supraocular, about 3/4 length of parietal; parietal 1.33 to 1.5 times length of prefrontal; paraparietal surrounded by 5 scales and shields; nasal oriented laterally, equal to postocular; preocular present; both oculars as high as eye; eye about 2/3 eye-mouth distance; 5 supralabials, third and fourth entering orbit, fifth the largest, fourth almost as long as fifth along ventral border, dorsal margin of fourth labial half of its ventral margin; first 4 supralabials subequal along labial border; mental triangular, touching anterior chin shields; 5 infralabials, first 3 touching anterior chin shields; both pairs of chin shields meeting in midline; 3 gulars in midline between posterior chin shields and first ventral (Inger & Marx 1965). Body thickness index 0.041-0.052 (2 specimens); tail tapering gradually from base to a point; dorsal scales reduced to 4 rows on tail opposite third to ninth subcaudal anterior to terminal scute (Inger & Marx 1965). Hemipenis in holotype too small for accurate description, sex determined by examination of gonads (Inger & Marx 1965). Teeth: Ten modified maxillary teeth (3 specimens) (Inger & Marx 1965). Scale counts: Ventrals 147-155 in males (holotype 155), 154-161 in females; subcaudals 18-21 in males (holotype 18), 14-16 in females; total length males 317 330 mm. (holotype 317), females 368 370 mm.; ratio of tail length to total length 0.072-0.106 in males (holotype 0.072), 0.073-0.076 in females (Inger & Marx 1965). Coloration: holotype brown above, yellow below, the dark pigment endin g abruptly on center of third scale row; dorsal scales without network; head brown above, the dark pigment ending in an oblique line from upper edge of second supralabial to lower third of fifth; supralabials yellow, the first dark brown dorsally and anteriorly; asmallyellowspotnearlateralmarginofparietal; headimmaculate yellow below; ventrals immaculate yellow; dorsal brown color extending ventrally on tail to cover most of subcaudals, leaving a short yellow stripe along central part of each row of subcaudals (Inger & Marx 1965). |
