in the distinctness of the species. The specimens collected agree 

 in scales and proportions, but vary in markings and coloration 

 with the age. They agree in practically all details with Peters's 

 description. The following is a description of a large adult 

 male: 



Description. — Rostral high; the supranasals constantly form 

 a suture; prefrontal large, as wide as long, making a narrow 

 suture with the frontal ; prefrontals narrowly separated ; frontal 

 bordered by the first 2 supraoculars; first superciliary large, 

 easily mistaken for a supraocular; frontoparietals and inter- 

 parietal distinct, the latter separating the parietals; a pair of 

 nuchals; nasal rectangular, as long as first labial, followed by 

 2 loreals, second much the larger; 2 enlarged scales under the 

 fore part of the eye; 4 supraoculars, second largest; 7 super- 

 ciliaries, first very large; 7 supralabials, fifth largest, entering 

 the eye ; 3 temporals the size of the seventh labial ; mental large, 

 followed by an unpaired chin shield and 2 large paired shields; 

 7 lower labials; ear opening small, nearer the foreleg than the 

 snout; 30 rows of scales around the body; preanals somewhat 

 enlarged; the adpressed hind leg reaches beyond the wrist of 

 adpressed foreleg. Dorsal scales, at least those on the posterior 

 half of back, tricarinate, occasionally quinquicarinate. 



Color in life. — Owing to the extreme variation I append de- 

 scriptions of specimens of various ages. Young (extreme tip 

 of tail regenerated): Length, 132 millimeters. Body above 

 glossy coal black with a series of brilliant orange-yellow bars 

 from the tip of the snout to the end of the tail ; 3 bars in front 

 of eye, first on the rostral; 2 in front of eye; 2 between the 

 eyes, having only a single representative below the eye; the 

 sixth lies across the occipital region passing through the corners 

 of the mouth ; 2 or 3 bars across the neck ; 6 on the body in front 

 of the hind leg, with 13 much wider bars on the tail; the latter 

 bars are more orange than yellow; legs and digits barred with 

 canary yellow*; regenerated tail brick red ; below, the bars widen 

 and loose themselves in the immaculate canary yellow of the 

 abdomen, giving the appearance ventrally of a series of black 

 belts, the ends of which are pointed and fail to meet. In a 

 specimen 180 millimeters long (snout to vent, 76 millimeters), 

 these markings are still very distinct; however, in a specimen 

 measuring from snout to vent 92 millimeters (tail broken and re- 

 generated) , the characteristic markings of the young are scarcely 

 distinguishable save a series of lateral bars of ocellated black 

 and cream, scarcely traceable dorsally. These are the remains
